Title: A Primer on Remote Sensing of Water Quality

Presenter: Michael Meyer and Tyler King, USGS

Time: 8:00 am – Noon

Length: 4 hours

Description: The use of remote sensing data for monitoring water quality and aquatic ecosystem integrity has grown rapidly.  Remote sensing empowers researchers to build a historic record of observations and to scale-up point measurements throughout a system, especially in areas that are difficult to access or only experience infrequent sampling. In tandem with growing opportunity to evaluate spatial and temporal trends in water quality, there is a growing catalog of remote sensing data products and toolkits. Yet, the data skills required to work with these tools are uncommon in most aquatic sciences training programs, potentially isolating certain user communities.  We will host two, 1.5-hour workshops to provide concrete, hands-on training in working with remote sensing data for evaluating water quality constituents, with the goal of priming learners with the principles of using remote sensing to assess water quality. The first 1.5-hour workshop will focus on using existing, analytically-friendly, derived datasets (e.g., AquaSat, RiveRS, LimnoSat-US). The second 1.5-hr workshop will focus on using cloud computing infrastructures (e.g., Google Earth Engine, Amazon Web Services) to extract USGS Landsat data for continental-scale analyses. These workshops will assume learners are familiar with at least one object-oriented coding language (e.g., R, python, MATLAB).


Title: Transatlantic Land Imaging Collaboration: Integrating Operational Capabilities to Meet User Needs Worldwide

Presenter: Tim Stryker, USGS

Time: 8:00 – 10:00 am

Length: 2 hours

Description: Learn the latest information about current and future land imaging collaboration among the USGS, NASA, European Commission, and European Space Agency. Officials from these agencies will update workshop participants on current and future U.S. and European coordination of the Landsat and Copernicus/Sentinel 2 satellite programs to better support U.S., European, and global user needs.


Title: Build a pixel with 50 years of Landsat to share an important story or memory

Presenter: Peder Nelson, OregonView + Oregon State University

Time: 10:15 am – 12:15 pm

Length: 2 hours

Description: To celebrate 50 years of Landsat-based Earth Observations, this workshop will dive into the life histories of Landsat pixels. Contribute to generational science and education by archiving some of your knowledge for the present and future.  You will have the opportunity to 1. learn characteristics about the Landsat Time-Series, 2. survey a diversity of stories that have been imaged over this period, 3. explore and characterize a location of personal interest, 4. Record and share a story or memory about these Landsat pixels.


Title: Demystify SAR for Climate Resilience and Sustainable Future Initiatives

Presenter:  Dr. Lorraine Tighe, Esri

Time: 1:30 – 5:30 pm

Length: 4 hours

Description: Climate change impacts us globally. These environmental crises come in many forms, from declining air quality to rising sea levels, diminishing biodiversity, and extreme weather hazards. SAR sensors are vital in understanding our changing climate. Synthetic Aperture Radar (SAR) Earth observations sees through darkness, cloud, haze, and smoke, offering a 24/7 vantage point needed to assess, understand, and respond to a broad range of climate change. However, SAR technologies are complex and often a barrier to climate research. This workshop will remove that barrier. SAR Earth observations combined with GIS (geographic information systems) technology create a new window that increases our knowledge of Earth’s changing landscape. Together, SAR and GIS help build a detailed picture of potential climate hazards by combining Earth observations, demographics, and business activity societal data with climate science-based risk assessments. The purpose of this workshop is to engage the attendees in exploring ideas, approaches, and project results for understanding the changing Earth’s surface using SAR and GIS technologies. The three-hour workshop centered on SAR Earth observations provides additional information to assess and respond to climate change using GIS technologies. The following topics are covered:  1] High-level SAR introduction/basics 2] SAR Platforms and SAR Analysis Ready Data  3] Climate Change: Adaptation, Mitigation, and Resilience GIS workflows Using time series analysis in GIS, AI tools & analysis, InSAR techniques, and DInSAR  4] Upcoming Global Products, SAR Tools and Services.


Title: Climate Change Monitoring and Impacts Assessment using NASA Earth Observations

Presenter: Sean McCartney, NASA / SSAI

Time: 1:30 – 5:30 pm

Length: 4 hours

Description: Addressing our changing climate is a complex and multi-dimensional issue facing the global population. Climate data records provide evidence of climate change through changes in key indicators such as global land and ocean temperature, sea levels, polar and glacial ice extent; frequency and severity of extreme weather such as hurricanes, heatwaves, wildfires, droughts, floods, and precipitation, and cloud and vegetation cover. This information coupled with theoretical models and scenarios of future emissions form a fundamental basis for climate mitigation, adaptation, and risk management planning in all parts of the world and across many elements of society and ecosystems.    This four-hour workshop, hosted by the NASA Applied Remote Sensing Training (ARSET) Program, will provide an overview of NASA resources for monitoring climate change and its impacts on various sectors such as extreme weather, water, food, and health. We will define the terminology and the role of Earth observations in climate change assessment, and then provide an overview of NASA climate models suitable for emissions policy, impacts, risk, and resilience applications. The workshop will provide hands-on examples using open source tools to visualize and access information and data relevant to understanding and planning for climate change. The workshop will also preview NASA’s Earth System Observatory, a new set of Earth-focused missions to provide key information to guide efforts related to climate change, disaster mitigation, wildfires, and improving real-time agricultural processes.

The Technical Program Committee has selected the following technical sessions for the Pecora 22 conference program. 

Title: Addressing Local Decision-Making Needs through the Application of NASA Earth Observations
Organizer: Kenton Ross, NASA

The NASA DEVELOP Program takes a unique approach to cultivating future Earth scientists and enhancing environmental management and public policy decision making around the globe. The program conducts rapid, interdisciplinary feasibility studies that apply NASA’s Earth observations to address real-world community concerns. This advances environmental understanding by improving the ability of the geoscience workforce to recognize, understand, and address environmental issues facing communities. This session highlights projects that apply NASA’s Earth observations, GIS, and remote sensing techniques to a broad range of decision-making processes related to themes such as agriculture & food security, disasters, ecological forecasting, health & air quality, and water resources.

Title: From three to many shades of water color: The legacy of Landsat and its prospects
Organizer: Nima Pahlevan, SSAI / NASA

A half-century of Landsat satellite sensor observations has enabled the development, testing, and validation of novel methodologies for studying aquatic ecosystems across global inland and nearshore coastal waters. These studies typically range from assessing optically relevant water quality indicators (concentrations of sediment, pigments, dissolved organic matter) and color of water, characterizing and mapping benthic compositions (corals, seagrass) in optically shallow waters, and detecting surface algae, and emergent vegetation. Through Landsat’s consistent multi-decadal thermal measurements and the derived high-quality surface temperature products, identifying trends and changes in water surface temperature due to climate variability and extreme weather patterns has also been made possible. This session calls for abstracts that address how the Landsat program has contributed to all the advancements in the aquatic remote sensing domain over the course of a half-century and how it is envisioned to advance our understanding of aquatic environments within the next decades in combination with other remotely sensed datasets, such as those offered through the Copernicus Sentinel missions (i.e., Sentinel-2, Sentinel-3), proof-of-concept hyperspectral satellite sensors (e.g., PRISMA), commercial sector, and low-altitude platforms. Studies focusing on shifts in watercolor and temperature, mapping aquatic vegetation, floating algae, spills, surface scums, and harmful algal blooms (HABs), quantifying water quality proxies (e.g., pigment concentration), benthic composition, and bathymetry, as well as algorithms and processing methods across rivers, lakes, reservoirs, water supplies, and coastal estuaries, are encouraged.

Title: Community Science through Remote Sensing of the Environment
Organizer: Peder Nelson, Oregon State

In this session, we will highlight projects that are using participatory science to increase the quantity of in-situ reference and validation data. In addition to simply collecting data for others to analyze, citizen science has the opportunity to increase scientific literacy, provide pathways for under-represented scientific voices, and create a new type of global monitoring network.

Title: Remote sensing of shallow-water bathymetry: Methods for a new era
Organizers: Monica Palaseanu-Lovejoy, Jeff Danielson, Dean Gesch, USGS

Improved understanding of physical changes in the Earth’s shallow to intermediate water regions is crucial to understanding the impacts of sea-level rise, extreme storm events, submarine environments, sediment transport, and growing human populations pressure on coastal, lacustrine, and polar environments. Recent interest in remote sensing retrieval of shallow-water bathymetry is being driven by the availability of multispectral and stereo satellite imagery, altimetry, and SAR satellite data at global scale with increased spatial and temporal availability. Bathymetric lidar from conventional airborne platforms is readily available and supports higher-resolution bathymetric mapping over smaller areas providing data for calibration and validation of satellite-derived bathymetry. NASA’s ICESat-2 green laser altimeter now acquires bathymetric profiles at a global scale and the near future Surface Water and Ocean Topography (SWOT) satellite with its smaller footprint and additional cross-track slope measurement, could improve the accuracy of predicted bathymetry from shallow to deep ocean. Collectively, these datasets and techniques can be combined to map large regions of the littoral zone to help fill in critical gaps not acquired by traditional mapping systems. We welcome presentations and illustrated posters that highlight new multispectral / stereo / SAR / lidar observations to map shallow water bathymetry, individually or in combination; new or improved algorithms and tools for bathymetric estimation; open-source software for satellite derived bathymetry estimation; optimal fusion of direct and remote observations; and new scientific advances enabled by any of the above.

Title: The Geospatial Cloud
Organizer: Matthew Hanson, Element 84

The last few years has seen advancements in geospatial interoperability in the cloud. Cloud-native data storage formats (e.g., Cloud-Optimized GeoTIFFs, Zarr) combined with new standards for search and discovery (STAC, OGC APIs) and libraries for enabling cross-format parallel computing (Dask, XArray, OpenDataCube, fsspec) have enabled easy scaling for massive amount of Earth Observation data. The talks in this session will give an overview of the advances in open-source Geospatial Cloud technologies including data and metadata formats for enabling processing at scale with distributed approaches.

Title: Monitoring, Assessing, and Projecting Land Change Impacts with LCMAP Science Products
Organizers: Jennifer Rover, Kristi Sayler, and Jesslyn Brown, USGS

The U.S. Geological Survey’s (USGS) Land Change, Monitoring, Assessment, and Projection (LCMAP) initiative produces land surface change science products based on the Landsat archive. LCMAP leverages the USGS Landsat Program’s decades of land imaging, future Landsat acquisitions, time-series modeling, and USGS Earth Resources Observation and Science (EROS) Center scientific expertise. The most recent LCMAP Science Collection includes 10 land cover and land surface change products for the time period 1985–2021 for the conterminous United States and Hawaii. The integrated products are the basis for applications and assessments designed to strengthen our understanding of the drivers of change, identify potential consequences of change on human and natural systems, and offer greater insight into the impacts and feedbacks of climate change. Presentations in this session will demonstrate how (1) a long (35+ year) historical record and (2) high temporal frequency land cover and surface change data enable an improved understanding of land change patterns, trends, causes, and consequences. Investigations that support the management communities’ decision-making processes are encouraged to submit.

Title: Agricultural Monitoring with Landsat data
Organizers: Chris Justice and Alyssa Whitcraft, University of Maryland

The first Landsat mission launched in 1972 was designed with Agricultural monitoring as a key application area. These early Landsat observations were the primary tool for developing the legacy USDA programs for agricultural monitoring including LACIE and Agristars, that lay the foundation for using satellite data for monitoring where and when crops are growing, monitoring crop condition as the growing season progresses, and estimating crop yields and total production from space. Since 2009, USDA has relied on Landsat data to map operationally dozens of crop types grown across the US as part of its Cropland Data Layer Program setting a standard for other countries around the globe for identifying which crops are growing where in their own countries. The 50 year data record afforded by the Landsat program gives us a long- term global perspective, on how agriculture lands are changing, whether that is tracking the rapid the large scale industrial ranching and soybean cultivation in South America or agricultural abandonment following the fall Soviet Union and the subsequent intensification, to tracking the impacts of a warming climate and extreme weather on agricultural productivity. Landsat 9 provides us a critical extension of this data record for monitoring food supplies and when combined with other moderate resolution sensors, will help both the public and private sector inform and address crucial decisions on how we manage, grow and adapt our food production sustainably under a warming climate and with an increasing population. Whether that is informing farmer decisions on management practices that support soil health, supporting transparent and stable agricultural commodity markets, to providing early warning of impending crop shortfalls, or supporting more efficient and effective agricultural insurance schemes.

Title: Developing Capacity to Apply Earth Observations for Global Societal Benefit
Organizer: Nancy Searby, USGS

Fifty years of high-quality, open-access Earth observation (EO) data harbor enormous potential for societal benefit when applied to modern challenges. In addition to EO data, NASA’s Socioeconomic Data and Applications Center (SEDAC) supplies information about human interactions in the environment, which can help decision makers understand the human impacts and vulnerabilities and advance environmental justice (EJ) initiatives. Developing capacity in current or potential data users is a crucial component to ensure these data reach their full potential and help decision makers across sectors and disciplines tackle some of the biggest questions facing society, such as climate change impacts, disaster mitigation and response, and the intersectionality of EJ efforts. In response to this challenge, the EO capacity building community is investing in the growth of individual and institutional knowledge of EO data, services, and applications. This session will provide a forum for networks, organizations, and individuals to share best practices, initiatives, and case studies that support EO capacity development. These presentations will focus on developing capacity to improve our understanding of the human impacts of environmental challenges, such as disasters, climate change, EJ, and more, on scales ranging from individual communities to broad regions.

Title: Landsat-derived Global Rainfed and Irrigated-Cropland Product at 30m (LGRIP30) for World’s Food and Water Security in the twenty-first Century
Organizer: Prasad Thenkabail, USGS

This special session will present and discuss the world’s first Landsat-derived Global Rainfed and Irrigated-Cropland Product at 30m (LGRIP30). The product is developed taking global cropland extent product ( as baseline. Multi-date time-composites of Landsat Operational Land Imager (OLI) data of the entire world were used for the years 2014-2016. Irrigated and rainfed cropland mapping algorithms (CMAs) included several machine learning algorithms (MLAs), decision trees (DTs), and quantitative spectral matching techniques (SMTs) applied on multidate Landsat analysis ready data cubes for distinct agroecological zones (AEZs) of the world utilizing the knowledge base developed from large sets of reference data sourced from field visits, sub-meter to 5-m very high-resolution imagery, and multiple other country and regional products. Irrigated and rainfed cropland areas were computed for every country in the world and compared with the UN FAO National statistics. Accuracies, errors, and uncertainties were performed using independent validation data of over 10,000 samples providing error matrices with overall-producer’s and user’s accuracies for irrigated and rainfed croplands in each AEZ as well as the entire world.

Title: Performance of new and old generation spaceborne hyperspectral data relative to advanced multispectral data in the study of leading agricultural crops of the world
Organizer: Prasad Thenkabail, USGS

This special session will evaluate the performance of new and old generation spaceborne hyperspectral data (DESIS, PRISMA, Hyperion) relative to advanced multispectral data (Landsat, Sentinels). The primary focus will be studies pertaining to world leading agricultural crops such as wheat, rice, barley, corn, soybeans, and cotton which occupy an overwhelming proportion of the world’s 1.873 billion hectares of agricultural croplands.” Hyperspectral sensors include the German Aerospace Center’s (Deutsches Zentrum fur Luft- and Raumfahrt; DLR’s) Earth Sensing Imaging Spectrometer (DESIS) on board the International Space Station’s (ISS), the polar-orbiting Italian Space Agency (Agenzia Spaziale Italiana, ASI’s) PRISMA (PRecursore IperSpettrale della Missione Applicativa), and Earth Observing-1 (EO-1) Hyperion. Advanced multispectral data include Landsat and Sentinels. This session will present and discuss opportunities and challenges in utilizing hyperspectral data relative to advanced multispectral data, performance of various machine learning classification algorithms utilizing optimal hyperspectral narrow bands (HNBs), development of hyperspectral vegetation indices (HVIs), establishing global hyperspectral imaging spectral libraries of agricultural crops (GHISA), and modeling biophysical and biochemical quantities using various HVIs, and cloud computing mechanisms.

Title: Ladies of Landsat: Power of the Pixel Panel
Organizers: Kate Fickas, Morgan Crowley, Crista Straub, USGS, McGill University

Ladies of Landsat is a Twitter-based organization that started officially in 2018. Led by a group of women hoping to make the field of Earth observation (EO) more equitable and inclusive for underrepresented scientists, they now have grown over 8,000 members! The field of EO has been dominated by the voices of those who have historically held positions of power, and so Ladies of Landsat are working from multiple directions to achieve a broader mission to make an impact on the field. First, they work bottom-up to amplify the representation of women and other underrepresented scientists in EO science. Second, they lead top-down calls for action from leaders in power and active allies who have the capacity to change the status quo when it comes to diversity, equity, justice, inclusion, and accessibility (DEJIA) in remote sensing. It’s an exciting time to be in the field of EO as significant advances are being made every day towards increased gender representation. In the past, barriers to mentorship, data accessibility, education, outreach, and collaboration limited women and other underrepresented scientists from using remote sensing and EO. However, these barriers continue to be broken down with the burst of free and open cyberinfrastructure, open science, and accessible communication. With a more diverse, equitable, and inclusive EO community comes more thoughtful, meaningful, and innovative research and applications. Importantly, there is also an increase in representation of who is using the data along with this progress, which is essential for girls and women of all ages to see that folks from all backgrounds, careers, and fields can be part of a broader EO community. In this panel, Ladies of Landsat of different backgrounds, career stages, sectors, and geographic locations will discuss important topics such as: how EO data has helped open opportunities for underrepresented groups around the world, career trajectories, barriers, challenges and opportunities, parenthood, and the future of EO. Representation matters! Folks of all career stages crave the ability to see women and other underrepresented groups in positions of scientific power, discuss their path, and able to make a difference with their work. Showcasing Ladies of Landsat in this panel creates a platform for this to occur on an international scale.

Title: Advancing Geospatial Data Science
Organizer: Peter Doucette, USGS

This special session will discuss strategic directions to advance the utility of geospatial data science to better explain, model and estimate changes to the Earth’s land surface through time in support of decision making for societal benefit. Topics for consideration include the application of high performance and cloud computing environments; machine and deep learning methods; integrated Earth observation data for advancing time-series analysis; and environments to facilitate cross agency collaboration to conduct data science.

Title: Power, Promise, and Challenges in Remote Sensing of Water Quality
Organizer: Michael Meyer, USGS

Remote sensing technology, algorithm development, data pipelines, and suites of satellite constellations have created unprecedented opportunities to evaluate changes in water quality from local-to-global as well as daily-to-decadal scales. With these opportunities, new challenges have also arisen. New data sources and algorithms must be tested and calibrated; increasing data volumes require expansion of data storage and processing IT infrastructure. The fusion of data from both public and private sector satellites necessitates coordination of disparate formats and uncertainty levels. Together, these challenges have widened the scope of and participation in remote sensing of water quality, and increased demand for cross-discipline expertise in both remote sensing and evaluation of water quality parameters. To build a conversation around multifaceted developments in the remote sensing of water quality, this session invites contributors to share technical, modeling, and analytical developments in the remote sensing of water quality as well as synthesis of methods for atmospheric corrections, scaling of cloud and other high-volume computing environments existing data. We especially encourage contributions from agencies and individuals focused on making remotely sensed water quality data accessible and useful to water resource managers and the public. We envision this session will host a range of presentation topics, including but not limited to novel, reduction of uncertainty in satellite-based water quality estimates, building remote sensing data pipelines and data products, and applying remotely sensed data for basic and applied research questions.

Title: Integrated Analysis of Land Imaging Satellite Performance and Benefits

Organizer: Greg Snyder, USGS

Federal agencies and other organizations need tools to make informed decisions when selecting Earth observation (EO) data sources from an array of current and emerging government, commercial, and international satellites.  These satellites are increasingly relevant to environmental monitoring, natural resource management, water quality, natural hazards, wildland fire, climate, and other areas. This session focuses on recently developed U.S. Geological Survey and partner agency methods for assessing how well user applications can be satisfied by current and proposed satellites.  The methods can be applied to inform next generation satellite missions (e.g., Landsat Next), assess global satellite architectures and data gaps, or guide Federal commercial satellite purchase activities. The outcomes of these assessments are complemented by social and economic analysis related to the value of imagery to various societal sectors and purposes. The analysis advances an awareness of the many benefits of EO to society, and therefore plays a key role in the future growth of EO activities in the public interest.

Title: A Half Century of Remote Sensing Success in the ASPRS

Organizer: Raechel Portelli & Dr. Bob Ryerson, FASPRS

The ASPRS and its journal have played a major role in the development of the field of remote sensing. This role has begun to be examined by a team of ASPRS members interested in how the past can contribute to future understanding. The session will provide the historical context as we look to the future.

Title: Progressing National SDG Implementation through Earth Science

Organizer: Argyro Kavvada & Cynthia Schmidt, NASA

In 2015, 193 member states of the United Nations unanimously adopted a global framework to end poverty, protect our planet, and promote peaceful and inclusive societies by 2030. The sustainable development agenda comprises 17 Sustainable Development Goals (SDGs), divided into 169 targets and 231 indicators. Since the adoption of the SDGs, governments and other stakeholders — e.g., civil society organizations, academia, research networks, NGOs, entrepreneurial firms —  have been making progress in leveraging Earth science information to inform development indicators; manage targets; prioritize implementation programs; and evaluate outcomes. From measuring climate risks and urban growth, to monitoring biodiversity hotspots and sustainable forest management, Earth science data and derived insights play a key role in sustainable solutions. This session includes presentations on examples of use and integration of Earth observations in a country’s (or countries’) processes to meet SDG targets or monitor SDG indicators as well as associated challenges and lessons learned.

This session invites presentations on:

  • Practical examples of use and integration of Earth observations or models in a country’s (or countries’) processes to meet an SDG target or monitor an SDG indicator.
  • Examples of integration of Earth observations with socio-economic data into national statistical systems.
  • Examples of integrated solutions across SDGs to respond to complex development challenges.
  • Examples of public – non-public partnerships to accelerate government and stakeholder efforts to address the SDG targets and indicators within the context of climate variability and change.

Title: How Citizen Science Can Fill the Gaps in Landsat Earth Observations

Organizer: Jake Rose, Chronolog


Citizen science has two major benefits for earth observations. First is the ability to scale. By crowd sourcing the work of making observations, the public can document areas from the ground that satellites and professional scientists either aren’t able to reach or lack the capacity to cover. Second is delivering scientific findings back to the public. By involving amateur observers in the data collection and/or data analysis step of the scientific process there are more opportunities for the public to understand the change happening in the environment and the system in place to document it.     In this session we will profile individual citizen science programs. Each separate program has a different method of collecting observations, and different comparative advantages and limitations. We will explore the benefits of combining these datasets to help fill the gaps left behind by Landsat observations. We will highlight GLOBE Observer and Chronolog.    The end result of complementary citizen science programs collaborating is a richer dataset that is easily interpreted by the public because it is created by the public. Access to these resources tailored specifically to a general audience creates a better visual understanding of the changing earth and provides evidence needed for the public to advocate for responsible management.

Title: 50 years of Landsat terrestrial monitoring – past, present and future

Organizer: David Roy, Michigan State University & Curtis Woodcock, Boston University

The Landsat record is unbroken over 50 years, with most land locations acquired at least once per year since 1972.  The successful September 2021 launch of the NASA/USGS Landsat-9 mission secured the continuity of the longest global environmental satellite record. Today, eight Landsat missions provide a global environmental baseline needed to contextualize change at scales of human influence, with ongoing continuity to be provided by the Landsat-Next mission planned for the end of this decade.  Landsat data are used for scientific discovery and for managing and monitoring terrestrial resources across many thematic domains, and in support of local to national programs and reporting linked to multilateral agreements. Today, Earth observation data are recognized as a public good, and free and open data, with advances in internet, cloud computing, and open-source software, are broadening and democratizing science. Analysis-ready and harmonized data sets derived from Landsat, the sister European Sentinel-2 satellites, and commercial systems, are being developed. To help celebrate the success of the 50 years of Landsat, papers that reflect on past, present and future uses of Landsat data for applications and science are encouraged.

Title: Advances in Quantifying Effects and Extent of Land-Use/Land-Cover Change and their Impact on Decision Making Processes affecting Food Security and Environment

Organizer: Christine Evans, SERVIR Science Coordination Office

Land-use and land cover change (LULCC), including agriculture and water, has the potential to drastically affect the hydrologic cycle, forest dynamics, and carbon emissions. The emerging challenges of land system changes from a natural resource and management perspective include (1) deriving timely and accurate LULCC through the use of Earth observations (EO) products, (2) deriving drivers of LULCC to study impacts of climate change and develop climate mitigation strategies, and (3) modeling LULCC to predict future scenarios and inform forecasts of food security and environmental degradation. For over 15 years, SERVIR, a joint initiative between NASA, USAID and leading geospatial organizations in Asia, Africa and Latin America has worked to enhance the capacity of countries to use EO products for decision making and addressing emerging challenges.  This session invites submissions from applied projects like SERVIR, that use emerging geospatial techniques such as remote sensing, modeling, artificial intelligence, assimilation of observed vegetation characteristics, and in situ observations for monitoring LULCC. We welcome studies exploring disturbance from natural versus anthropogenic sources and those dealing with uncertainty in selection of land cover datasets, statistical methods or application-oriented studies, using cloud-based services (e.g., Google Earth Engine), that can improve LULCC decision-making processes at various scales. A capacity building aspect is encouraged, focusing on how the study and methodology is transitioned to end-user organizations for enhanced decision-making and resilience.

Title: Using Earth Observations for Marine and Freshwater Applications Research

Organizer: Maury Estes, NASA Ecological Forecasting Program and UAH

The NASA Ecological Forecasting Program supports the use of Earth Observations to promote conservation and sustainable management of marine and freshwater resources.  The goal of projects funded under this program is to provide a research foundation and the development of products and tools for stakeholders to use for decision-making.  In this session, projects focused on marine and freshwater ecosystems will be discussed including coral reefs, polynyas in Southern Ocean, seascapes, and phytoplankton studies with the common theme of conserving living marine and freshwater resources for the benefit of society.  Presentations will focus on the integral role of Earth Observations and how the tools and products provided to stakeholders benefit management and conservation decisions.

Title: AmericaView Demonstrates the Power of Landsat Imagery

Organizer: Russell G. Congalton, University of New Hampshire/AmericaView

We will present 6 talks from AmericaView members that demonstrate various examples showing the power of Landsat imagery.

Title: High-Latitude Aquatic Remote Sensing Using High-Resolution Sensors

Organizer: Wesley J. Moses, Steven G. Ackleson U.S. Naval Research Laboratory & Cara Wilson, NOAA CoastWatch/PolarWatch

The coastal Arctic Ocean is undergoing rapid physical and ecological changes as a result of a warming climate.  Shorelines are continually changing due to coastal erosion caused by thawing permafrost. Increased sunlight penetration into the water column due to thinning of the ice layer and influx of nutrients into the coastal ocean from riverine transport of materials released from thawing permafrost are affecting primary production and causing disruptions to the food chain in ways that lead to changes in migration patterns of organisms at higher trophic levels.  The high spatial resolution afforded by spaceborne sensors such as the Landsat series, Sentinel-2, and WorldView-2/3 and the emergence of autonomous airborne sensing systems provide an effective means of documenting and monitoring key lacustrine, riverine, estuarine, and coastal properties and processes affecting the coastal Arctic ecosystem, such as sediment and dissolved matter transport, shoreline erosion, sea ice distribution and dynamics, and phytoplankton biomass.  We encourage presentations of studies involving the use of high-spatial-resolution multispectral and hyperspectral imagery to address these and other environmental issues pertaining to the coastal Arctic ecosystem in a rapidly changing climate.  Time-series studies involving historical datasets, investigations that integrate data from multiple in situ and remote sensors, and applications of innovative techniques for retrieving biophysical properties of water are especially welcomed.

Title: Analysis Ready Data: New Providers, New Opportunities

Organizer: Andreia Siqueira, Geoscience Australia

The term “Analysis Ready Data” varies and has different meanings depending on which user group or/and data provider is using/producing it. Back in 2015, the Committee on Earth Observation Satellites (CEOS) Land Surface Imaging Virtual Constellation (LSI-VC) provided one definition for ARD targeting land products (CEOS Analysis Ready Data for Land – CARD4L). CEOS LSI-VC also created a framework and Product Family Specifications (PFS), which provides the means for data providers to assess and meet requirements for CEOS ARD compliant datasets. Since then, CEOS Agencies have been working towards these specifications to ensure datasets comply with CEOS ARD specifications. The private sector came on board and is recognizing the importance of CEOS ARD; particularly with regards to the value of having Government datasets comparable and interoperable with their own datasets. This session is being organized by CEOS LSI-VC in collaboration with Geoscience Australia and USGS. Its objective is to continue the dialogue between CEOS and the private sector on the ARD topic in particular to explore new opportunities and challenges for data providers regarding user needs, discovery and access of CEOS ARD complaint datasets.

Title: Intercomparison and Synergies Between Multispectral and Imaging Spectroscopy Earth Observation Data in Preparation for the Future

Organizer: Christopher Crawford, USGS

Earth-looking visible-to-shortwave infrared (VSWIR) imaging spectroscopy (also referred to as hyperspectral) data from US and international research and demonstration missions are becoming more widespread in availability and geographic coverage, and data volumes can only be expected to grow during this decade. Operational multispectral imaging missions such as US Landsat and Europe Sentinel-2 when coupled together, are providing predictable and frequent revisit coverage (<3 days) at medium resolution ground sample distances (10 to 30 meters) that continue to lengthen the high-quality, continuous Earth observation record that has become commonplace in recent decades. Thus, this session encourages submission of research work that is focused on intercomparison and synergies between imaging spectroscopy and multispectral imaging data that leverages higher spectral resolution with high temporal revisit to advance terrestrial remote sensing capabilities in the thematic science application areas of minerals and geology, aquatics and water quality, snow hydrology and ice dynamics, agriculture, and vegetation ecology. As such, cross mission comparisons will facilitate more intentional remote sensing measurement coordination as future missions undergo development in the 2020s.
