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.
In 1995 the USGS was in need of a Windows viewer for their data products, so they developed the dlgv32 application for viewing their DLG (Digital Line Graph) vector data products. Between 1995 and 1998 the dlgv32 application was expanded to include support for viewing other USGS data products, including DRG (topographic maps) and DEM (digital ...
The Libre Map Project was started by Jared Benedict and around 100 additional individuals contributing money to purchase (or "liberate") a full set of 1:24K scale USGS topographic maps in Digital raster graphic form. [1] The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone ...
Digital geologic mapping is the process by which geological features are observed, analyzed, and recorded in the field and displayed in real-time on a computer or personal digital assistant (PDA). The primary function of this emerging technology is to produce spatially referenced geologic maps that can be utilized and updated while conducting ...
This article contains a list with gratis (but not necessarily open source) satellite navigation (or "GPS") software for a range of devices (PC, laptop, tablet PC, mobile phone, handheld PC (Pocket PC, Palm)).
The data was entered in spreadsheet format or in ESRI shapefiles and submitted via e-mail to the USGS National Geospatial Technical Operations Center(s) in Denver, Colorado, and Rolla, Missouri. During the registration process, prospective volunteers submitted a list of the 7.5 minute quadrangle maps on which they wished to work.
PROJ (formerly PROJ.4) is a library for performing conversions between cartographic projections.The library is based on the work of Gerald Evenden at the United States Geological Survey (USGS), [2] but since 2019-11-26 is an Open Source Geospatial Foundation (OSGeo) project maintained by the PROJ Project Steering Committee (PSC).
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
