GRASS has been under continuous development since 1982 [3] and has involved a large number of federal US agencies, universities, and private companies. The core components of GRASS and the management of integration of efforts into its releases was originally directed by the U.S. Army - Construction Engineering Research Laboratory (USA-CERL), a branch of the U.S. Army Corps of Engineers, in ...
GRASS GIS: A Useful Tool for the Mountain Cartographer includes a grass script which allows one to generate a shaded relief of a lat-long DEM while taking into account the horizontal (E-W) stretching which normally makes lat-long reliefs unusable. What this does is allow the relief image for this tutorial to be produced in a single step rather ...

QGIS integrates with other open-source GIS packages, including PostGIS, GRASS GIS, SAGA GIS, and MapServer. [6] Plugins written in Python or C++ extend QGIS's capabilities. Plugins can geocode using the Google Geocoding API, perform geoprocessing functions similar to those of the standard tools found in ArcGIS , and interface with PostgreSQL ...

Using QGis will be mainly helpful in generating topographic backgrounds (png, svg), shaded reliefs (png), and administrative regions or borders (png, svg), and applying various styles to them. While GRASS GIS still seems to be the most common GIS software, it has a primarily command-line interface and can be
Cost distance tools are available in most raster GIS software: GRASS GIS (often bundled into QGIS), with separate accumulation and drain functions; ArcGIS Desktop and ArcGIS Pro, with separate accumulation (Cost Distance) and drain geoprocessing tools, as well as Corridor generation. Recently, starting with ArcGIS Pro version 2.5, a new set of ...
The use of the Web has dramatically increased the effectiveness of both accessing and distributing spatial data, two of the most significant challenges of desktop GIS. [ 1 ] [ 12 ] [ 13 ] Many functions, such as interactivity, and dynamic scaling, are made widely available to end users by web services. [ 14 ]
