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.
Survex is free and open-source cave surveying software, licensed under the GNU GPL. It is designed to be portable and can be run on a variety of platforms, including Microsoft Windows, Mac OS X, and Unix-like. Survex is very powerful cave survey software, and is actively developing into a complete cave visualization package.
These values are used to calculate an E value for the estimate and a standard deviation (SD) as L-estimators, where: E = (a + 4m + b) / 6 SD = (b − a) / 6. E is a weighted average which takes into account both the most optimistic and most pessimistic estimates provided. SD measures the variability or uncertainty in the estimate.
Therion is free and open-source cave surveying software designed to process survey data, generate maps and 3D models of caves, and archive [3] the data describing the cave and the history of exploration. Therion was developed by the Slovak cavers Martin Budaj and Stacho Mudrak [4] but is available in English.
In surveying, free stationing (also known as resection) is a method of determining a location of one unknown point in relation to known points. [1] There is a zero point of reference called a total station. The instrument can be freely positioned so that all survey points are at a suitable sight from the instrument.
Scribe is a markup language and word processing system that pioneered the use of descriptive markup. [ 1 ] [ 2 ] Scribe was revolutionary when it was proposed, because it involved for the first time a clean separation of presentation and content .
CSPro was designed and implemented through a joint effort by the developers of two earlier software packages that were used to capture, edit, and tabulate census and survey data on DOS-based machines: the Integrated Microcomputer Processing System (IMPS), developed by the U.S. Census Bureau, and the Integrated System for Survey Analysis (ISSA ...
For example, in statistical parsing a dynamic programming algorithm can be used to discover the single most likely context-free derivation (parse) of a string, which is commonly called the "Viterbi parse". [4] [5] [6] Another application is in target tracking, where the track is computed that assigns a maximum likelihood to a sequence of ...
