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.
Pakistan Flood 2022 : Computing the flooded area From June 2022 to October 2022, Pakistan experienced significant flooding in the Indus Valley that killed 1739 people. In this article, I describe how I used ProRaster Scientific to compute the area flooded based on...
NDVI Change Analysis at Coorabulka Station ProRaster Scientific 2022 – 2023 I used ProRaster Scientific to quantify the spatial and temporal changes in vegetation over a year at a large outback cattle station in Australia called Coorabulka. Coorabulka...
