GRASS is designed as an environment in which tools that perform specific GIS computations are executed. Unlike GUI-based application software , the GRASS user is presented with a Unix shell containing a modified environment that supports execution of GRASS commands, termed modules.
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 ...
A transport network, or transportation network, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. [1] ...
This tool is available in a variety of GIS and graphics software, including Photoshop, QGIS, GRASS GIS or ArcMap's Spatial Analyst extension. While these relatively simple tools have made shaded relief almost ubiquitous in maps, many cartographers [ weasel words ] have been unhappy with the product, [ which? ] and have developed techniques to ...
Capaware rc1 0.1 GRASS GIS 6.4 gvSIG 1.0 IDRISI Taiga 16.05 SAGA-GIS v. 2.0.3. The following open-source desktop GIS projects are reviewed in Steiniger and Bocher (2008/9): [13] GRASS GIS – Geospatial data management, vector and raster manipulation - developed by the U.S. Army Corps of Engineers; gvSIG – Mapping and geoprocessing with a 3D ...
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 code is designed to help scientists and civil protection authorities assess the risk of, and mitigate, hazards due to dry debris flows and avalanches. TITAN2D combines numerical simulations of a flow with digital elevation data of natural terrain supported through a Geographical Information System (GIS) interface such as GRASS.
