This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
Stereopair from DTM - Stereo pair from DTM operation creates a stereo pair from a single raster map and a Digital Terrain Model (DTM). These stereo pairs have the same usability as the Epipolar Stereo Pair. Patch 3.12a August 2003 ID Grid map - creates a polygon map given a coordinate system and an attribute table. The polygon map consists of ...
A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs. While a DSM may be useful for landscape modeling , city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies , [ 1 ] geological applications, and ...
The NASA Ames Stereo Pipeline (ASP) is an open-source software package for photogrammetry.It can create digital elevation models and ortho images from stereo planetary data acquired with NASA spacecraft, including for the Moon, Mars, and all other bodies with a solid surface, and also from commercial Earth-orbiting satellites, such as Digital Globe and any vendors who support the RPC camera ...
It can also use DEM (digital elevation model) files, and other graphic surface maps for rendering. A commercial version of the software is also available and is capable of creating larger terrains, renders with higher image resolution , larger terrain files, and better post-render anti-aliasing than the freeware version.
DTED supports many applications, including line-of-sight analyses, terrain profiling, 3-D terrain visualization, mission planning/rehearsal, and modeling and simulation. DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications ...
Version 8.0 (June 2019) is the successor of both Mountains 7.4 and SPIP 6.7 software packages ("SPIP" standing for "Scanning Probe Image Processor") after the acquisition by Digital Surf of the Danish company Image Metrology A/S, the editor of SPIP. [25] Version 8.0 also introduces the analysis of free form surfaces, called "Shells" in the ...
RoadEng is the original software program developed by Softree Technologies, with early adopters including government agencies like the USDA Forest Service. [3] Early versions of the software had three modules: road notes (where a surveyor enters their field notes), grade design, and plan view. [4]
