1 Landsat Program Update Timothy Stryker Chief, Outreach and Collaboration Branch National Land Imaging Program Western States Water Council Spring Meetings March 19-22, 2019 Chandler, Arizona U.S. Geological Survey 1

2 Department of the Interior Lands Manages 20% of U.S. land mass 2

3 USGS National Land Imaging (NLI) Program Delivers a national and global capability to ensure broad public and scientific availability of observations of the Earth s land surface: Create and preserve a long-term record of the Earth s land surface at local, regional, and global scales Expand scientific understanding and application of remotely sensed data to government and private users Support government policy and decision makers Guide National decisions to meet government needs for land science and land observation Coordinate and integrate civil Earth observations with other sources of data, including commercial and National Security space systems Fundamental goal: Ensure public availability of a primary data record about the current state and historical condition of the Earth s land surface 3

4 USGS NLI Program Components Satellite Operations Develop and operate systems to acquire, produce, preserve, and deliver products and services to meet civil Earth observation research and operational requirements Science, Research and Investigations Conduct science, research and technology investigations to improve upon and develop new products and services Manage National Civil Applications activities 4

5 Landsat 8 orbit for global coverage 5

6 Landsat Data Continuity Since 1972 Space & The Landsat Program has amassed the longest and most comprehensive record of the Earth s land surface in existence 6

7 Landsat Users and Applications Landsat is the most widely used remote sensing data source within Federal civil agencies Users: Federal Agencies (e.g., USDA, EPA, DOI, NASA, DoD, NOAA) State Agencies (e.g., Planning, Natural Resources, Transportation) University Researchers International Organizations (e.g., UNEP, WCRP, FAO, EC JRC, CSIRO, GA, DLR) Non Governmental Organizations (e.g., TNC, WRI, WWF, Resources for the Future) Commercial (e.g., Exxon-Mobil, MapBox, Descartes Labs, ESRI, Gallo, Harris Corp, ITT, MDA Federal) Foreign space agencies and U.S. and foreign commercial operators Cloud Service Providers (e.g., Amazon Web Services, Google) General Public Major Operational Programs Using Landsat: USDA National Agricultural Statistics Service Crop Type Mapping USDA Foreign Agricultural Service Commodity Forecasting USDA Risk Management Agency (Crop Insurance) USGS/EPA National Land Cover Dataset (NLCD) DOI/USDA LANDFIRE Program Western States Consumptive Water Use NOAA Coastal Change Analysis Program Global Forest Watch Forest Change Products Applications: Land use, land cover change Agriculture monitoring and forecasting Water resource management, availability, quality, usage Forest health, forest productivity, wildfire mapping and remediation Crop type mapping, yield estimation, efficacy of nutrients and pesticides Vegetation dynamics, ecosystem services, rangeland condition Land resource management Energy exploration and production Geologic mapping and mineral resource assessment Hazards monitoring and mitigation Emergency response, disaster assessment, risk mitigation Reference for instrument calibration Natural resource inventorying and monitoring Recreational planning & site suitability analysis Urban planning and development 7

8 Landsat Operations and Development Status Landsat 7 (1999- ) Landsat 7 (whiskbroom) Landsat 8 (2013- ) Landsat 9 (December 2020 launch) Landsat X (~ launch) Landsat 8 (pushbroom) 8

9 Landsat 9 Status Joint development between NASA and USGS (same as Landsat 8) Landsat 9 is a rebuild of Landsat 8 with targeted upgrades Overall mission making excellent progress Landsat 9 is on track for launch in December 2020, with transition to operations in March

10 Sustainable Land Imaging (SLI) Partnership Agreement for development of a multi-decade, spaceborne land imaging system Space systems: NASA Ground systems: DOI/USGS Future Landsat systems need to ensure Earth Observation continuity; USGS and NASA are open to new technologies, business approaches 10

11 Use Landsat for Commercial Near-real-time Water Management Evapotranspiration in vineyards E&J Gallo Vineyards, Lodi, California Serbina and Miller, Landsat and Water Case Studies of the Uses and Benefits of Landsat Imagery in Water Resources. Timely and continued thermal data is particularly valuable in agriculture as consumptive water use changes seasonally, even monthly. An increase in frequency of imagery promotes efficiency of irrigation schedules. -- Martin Mendez, E & J Gallo Winery,
