Blue Marble's first software product, the Geographic Calculator, [2] was developed in 1992 and released in 1993. The Geographic Calculator is a coordinate conversion library with a database of coordinate mathematical objects including projections, coordinate systems, datums, ellipsoids, linear and angular units. The tool is primarily used to ...
QGIS is a geographic information system (GIS) software that is free and open-source. [2] QGIS supports Windows, macOS, and Linux. [3] It supports viewing, editing, printing, and analysis of geospatial data in a range of data formats. Its name comes from an abbreviation of its previous name, Quantum GIS.

IntelliCAD is a CAD editor and development platform with an API published by the IntelliCAD Technology Consortium (ITC) through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of file types (i.e., .dwg, BIM, TIFF, etc.).
Where geographic coordinates are used as the argument of a trigonometric function, the values may be expressed in any angular units compatible with the method used to determine the value of the trigonometric function. Many electronic calculators allow calculations of trigonometric functions in either degrees or radians. The calculator mode must ...
In Japan, National Geographic’s pick for 2025 is Kanazawa, as an alternative to the much-loved but highly touristed city of Kyoto. The country’s center of gold leaf production, “we think ...
The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
Later the standard was transferred to ISO/TC211, Geographic information/Geomatics in 2001. The committee completely revised the second edition (ISO 6709:2008). There was a short technical corrigendum (ISO 6709:2008/Cor 1:2009) released in 2009. [1] The third edition ISO 6709:2022 was published in 2022. [2]
