Follow this tutorial to learn how to use the Raster Time Sequence, Time Differential, and Change Matrix processing operations in ProRaster Scientific. The tutorial uses the freely available Annual NLCD land cover product for the USA.
The GLO-30 DEM is a Digital Surface Model (DSM) of terrain that represents the surface of the Earth including buildings, infrastructure and vegetation.
It offers global coverage of the Earth at a resolution of one arcsecond (30 metres) and can be acquired for free from the ESA Copernicus Data Service Portal.
I have merged the 26,474 DSM tiles into a single MRR format terrain raster at 1×1 arc second resolution. I have also created classified rasters in MRR format for the Water Body, Filling and Editing masks.
GLO-30 is derived from the WorldDEM terrain raster product and is predominantly data acquired by the TanDEM-X satellite mission between 2011 and 2015. In 2024, GLO-30 is the highest quality and highest resolution, free terrain raster with global coverage that you can acquire.
I compute a correction to the Free Air Gravity for the NSW gravity database that incorporates Bouguer, Terrain, and Isostatic corrections for a spherical Earth model.
