About the dataJointly managed by NASA and the USGS, Landsat is the longest running spaceborne earth imaging and observation program in history. The Landsat program began in 1972, with the launch of Landsat 1. Beginning with Landsat 4, the program began providing mission to mission data continuity.Landsat Collection 2 Level-2 science products, imagery from 1982 to present, are made publicly available by the USGS. The continuity in this scientific record allows for critical and reliable observation and analysis of Earth processes and changes over time.The Landsat Level-2 multispectral imagery is available in ArcGIS Living Atlas of the World as a dynamic time enabled image service, accessible across the ArcGIS system and used to power this app. For more about the service and the data, see Landsat Level-2.About the appLandsat multispectral imagery helps to track and document land use and land change associated with climate change, urbanization, drought, wildfire, deforestation, and other natural processes and human activity.Through an intuitive user experience, this app leverages a variety of ArcGIS capabilities to explore and begin to unlock the wealth of information that Landsat provides. Some of the key capabilities include:Visual exploration of a Dynamic global mosaic of the best available Landsat scenes.On-the-fly multispectral band combinations and indices for visualization and analysis.Interactive Find a Scene by location, sensor, time, and cloud cover.Visual change by time, and comparison of different renderings, with Swipe and Animation modes.Analysis including threshold masking and temporal profiles for vegetation, water, land surface temperature, and more.
