ALT Southern California Earthquake Center Community Geodetic Model v2.0.0: deformation measurements from InSAR and GNSS. There are three maps. Lower left: GNSS velocities from both continuous (red) and survey (blue) measurements. Upper right: Sentinel-1 descending InSAR velocities from two tracks. Lower right: Sentinel-1 ascending InSAR velocities from two tracks. InSAR data span the interval 2014-2019; red colors indicate relative motion towards the satellite in the radar line-of-sight (LOS).

ALT Map of the United States with tile overlay indicating the number of additional tiles that are now available in Landsat Collection 2 U.S. Analysis Ready Data (ARD) compared to tiles that are available in Collection 1 between 1982 and 2021. The Application for Exploring and Extracting Analysis Ready Samples (AρρEEARS) logo in upper-right corner indicates that Landsat ARD C2 is now available in the AρρEEARS application. Background is Earth from space.
