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.
Common synonyms for geomorphometry are geomorphological analysis (after geomorphology), terrain morphometry, terrain analysis, and land surface analysis. Geomorphometrics is the discipline based on the computational measures of the geometry , topography and shape of the Earth's horizons, and their temporal change. [ 2 ]
The terrain generated the computer does a generation of multifractals then integrates them until finally rendering them onto the screen. These techniques are typically done “on-the-fly” which typically for a 128 × 128 resolution terrain would mean 1.5 seconds on a CPU from the early 1990s. [2]
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. The terrain is generated from a two-dimensional heightmap. The program contains facilities for importing and exporting ...
VistaPro is 3D scenery generator for the Amiga, Macintosh, MS-DOS, and Microsoft Windows.It was written by John Hinkley as the follow-up to the initial version, Vista. [1] [2] The about box describes it as "a 3-D landscape generator and projector capable of accurately displaying real-world and fractal landscapes."
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 ...
Quantitative geomorphology can involve fluid dynamics and solid mechanics, geomorphometry, laboratory studies, field measurements, theoretical work, and full landscape evolution modeling. These approaches are used to understand weathering and the formation of soils , sediment transport , landscape change, and the interactions between climate ...
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
