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.
The USGS SRTM data is based on NASA's SIR-C instrument. It is available in at the following versions: Version 1 (2003–2004) is almost the raw data. [7] Version 2.1 (~2005) is an edited version of v1. Artifacts are removed, but voids are not yet filled. There are 1-arcsecond data over the US. [8]
The main component on Landsat 7 was the Enhanced Thematic Mapper Plus (ETM+). Still consisting of the 15m-resolution panchromatic band, but also includes a full aperture calibration. This allows for 5% absolute radiometric calibration. [14] Landsat 8: 11 February 2013: active: 11 years, 10 months and 21 days
Integrated Software for Imagers and Spectrometers (Isis) is a specialized software package developed by the USGS to process images and spectra collected by current and past NASA planetary missions sent to Earth's Moon, Mars, Jupiter, Saturn, and other solar system bodies.
Some of the free software mentioned here does not have detailed maps (or maps at all) or the ability to follow streets or type in street names (no geocoding). However, in many cases, it is also that which makes the program free (and sometimes open source [ 1 ] ), avoid the need of an Internet connection, [ 2 ] [ 3 ] [ 4 ] and make it very ...
[10] Despite the high nominal resolution, however, some reviewers have commented that the true resolution is considerably lower, and not as good as that of SRTM data, and serious artifacts are present. [14] [15] Some of these limitations have been confirmed by METI and NASA, who point out that the version 1 of the GDEM product is "research ...
Demo map showing high-resolution SWBD coastlines. The SRTM Water Body Data (SWBD) is a geographical dataset (2003) encoding high-resolution worldwide coastline outlines in a vector format, published by NASA and designed for use in geographic information systems and mapping applications.
OpenSeaMap is a world nautical chart built as a mashup of OpenStreetMap, crowdsourced water depth tracks, and third-party weather and bathymetric data. OpenTopoMap uses OSM and SRTM data to create topographic maps. [92] Tactile Map Automated Production prints tactile maps that feature embossed streets, paths, and railroads from OSM. [93]
