Web-based GIS applications in planetary landform analysis
The storage, processing, integration and visualization of planetary datasets – mainly large raster files acquired via remote sensing – recently are carried out by geoinformatical software packages, while the results are often published on interactive webmap applications, for scientific teamwork coordination and public dissemination purposes as well.
The optical satellite images, digital elevation models (DEM) and other type of planetary data sources acquired via remote sensing techniques by orbiters’ instruments are searchable and downloadable via public internet databases, even can be combined with the direct field measurements and ground truth information of various landing space probes.
The best examples of this “planetary landform analysis” workflow are related to Mars, because of the great variety of detailed spatial datasets characterizing its surface morphology and topographic diversity. Either proprietary or open source GIS applications can be used for these planetary missions, depending on the specific tasks and software limitations.
