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 gravity model of migration is a model in urban geography derived from Newton's law of gravity, and used to predict the degree of migration interaction between two places. [1] In 1941, astrophysicist John Q. Stewart [ 2 ] applied Newton's law to the social sciences, establishing a theoretical foundation for the field of social physics.
erwin Data Modeler (stylized as erwin but formerly as ERwin) is computer software for data modeling.Originally developed by Logic Works, erwin has since been acquired by a series of companies, before being spun-off by the private equity firm Parallax Capital Partners, which acquired and incorporated it as a separate entity, erwin, Inc., managed by CEO Adam Famularo.
ArcGIS 8.1 also added the ability to access data online, directly from the Geography Network site or other ArcIMS map services. [42] ArcGIS 8.3 was introduced in 2002, adding topology to geodatabases, which was a feature originally available only with ArcInfo coverages.
MakeHuman is free and open-source, with the source code and database released under the GNU Affero GPL. Models exported from an official version are released under an exception to this, CC0, in order to be widely used in free and non-free projects. These projects may or may not be commercialised.
Tinkercad is a free-of-charge, online 3D modeling program that runs in a web browser. [1] Since it became available in 2011 it has become a popular platform for creating models for 3D printing as well as an entry-level introduction to constructive solid geometry in schools.
Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information. [1] [2] [3] The other branches of geography, most commonly limited to human geography and physical geography, can usually apply the concepts and techniques of technical ...
