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...
Wooroloo, Western Australia 2021 Bushfire Analysis using ProRaster Scientific In February 2021 a fast-moving bushfire burned from Wooroloo in the foothills to the east of Perth, west for 26 kilometres right to the edge of Greater Perth. The Wooroloo fire destroyed at...
Tjoritja (West MacDonnell Ranges) National Park 2023 Bushfire Analysis using ProRaster Scientific In March 2023 a large uncontrolled bushfire burned through much of the Tjoritja (West MacDonnell Ranges) National Park. The park is located in Central Australia to the...
2019-20 NSW East Coast Bushfire Season Analysis As part of the ProRaster Scientific and ProRaster Bushfire development, I have been studying the 2019-2020 bushfire event on the East Coast of New South Wales, Australia. I have used Landsat 8 and Landsat 9 data. The...
Publishing a C++ Win32 MFC Application to the Microsoft Store Introduction So, you have decided to publish a Win32 App to the Windows Store for fun or profit! Like mine, your App probably draws on large libraries in C++, and you want to develop the whole...
Exploring MERIT Hydro : Global Hydrogeography Rasters in ProRaster MERIT Hydro is a set of six global scale hydrogeography rasters prepared by the Global Hydrology Group at The University of Tokyo. The group is headed by Dai Yamazaki. In this series of three videos, I...
Rasters in MapInfo Pro Rasters (Grids and Images) have always been an integral part of MapInfo Pro. To complement the basic visualisation and interrogation capabilities in MapInfo Pro, users could purchase Vertical Mapper (sold separately) to provide advanced raster...
