The Worldwide Reference System (WRS) is a global notation used in cataloging Landsat data. Landsat 8 and Landsat 7 follow the WRS-2, as did Landsat 5 and Landsat 4. Landsat 1, Landsat 2, and Landsat 3 followed WRS-1.Shape files for WRS-1 and -2 (path/row...
The following information can be found on the GeoMAC application: Perimeter data gathered from the incident -- this information is gathered daily if the incident personnel has created and made available the perimeter Fire point data -- this data is...
Landsat has the optimal ground resolution and spectral bands to efficiently track land use and to document land change due to climate change, urbanization, drought, wildfire, biomass changes (carbon assessments), and a host of other natural and human-...
Land use change is perhaps the most observable of all environmental changes. Because land use change is connected to a wide range of societal and environmental processes, a robust body of land use change research helps us understand an extensive variety...
The LDCM Long Term Acquisition Plan (LTAP-8) and the Landsat 7 Long Term Acquisition Plan (LTAP) direct the acquisition of Landsat 8 and Landsat 7 scenes, respectively. Seasonality, land definition, historical cloud cover, gain settings, and sun angle...
Landsat 8's Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) sensors provide improved signal-to-noise (SNR) radiometric performance quantized over a 12-bit dynamic range.This translates into 4096 potential grey levels in an image compared...
The percentage of cloud cover is calculated when raw mission data from Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) are processed to Level-0R during ingest into the archive using the Automatic Cloud Cover Assessment (ACCA)...
The perimeters are updated in GeoMAC when the personnel on the fire create and make available a new perimeter.  Once the perimeter is made available, the perimeter is downloaded, quality checked and loaded into the database. Learn more: Living with Fire...
These pages provide the latest details and product information about each Landsat sensor:Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)Landsat 7 Enhanced Thematic Mapper Plus (ETM+)Landsat 4-5 Thematic Mapper (TM)Landsat 1-5...
Landsat is recognized globally to be a unique data set and the standard for land use trends and land change detection. Its community of users is considered to be broad and wide-ranging, touching nearly every field in land management and the terrestrial...
