MRE transforms are used to transform local datums over continent-sized or smaller regions to global datums, such as WGS 84. [30] The standard NIMA TM 8350.2, Appendix D, [31] lists MRE transforms from several local datums to WGS 84, with accuracies of about 2 meters. [32]
A WKT format is defined to describe the operation methods and parameters used to convert or transform coordinates between two different coordinate reference systems. The WKT 1 and WKT 2 formats are incompatible regarding coordinate operations, because of differences in the modelling. [13]
Use |display=title (or |display=inline,title) once per article, for the subject of the article, where appropriate. Per WP:ORDER , the template is placed at the bottom of the article in the 'end matter', after any navigation templates , but before all categories , including the {{ DEFAULTSORT }} template.
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
The second edition consists of a main part and eight annexes (Annexes A through H). The main part and Annexes A and C give encoding-independent general rules to define items to specify geographic point(s). Annex D suggests a display style for human interface. Annexes F and G suggest styles of XML expression. Annex H suggests string expression ...
Length of one degree (black), minute (blue) and second (red) of latitude and longitude in metric (upper half) and imperial units (lower half) at a given latitude (vertical axis) in WGS84. For example, the green arrows show that Donetsk (green circle) at 48°N has a Δ long of 74.63 km/° (1.244 km/min, 20.73 m/sec etc) and a Δ lat of 111.2 km ...
A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates.It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.
WGS84 angle to distance conversion: Image title: Length of one degree (black), minute (blue) and second (red) of latitude and longitude in metric (upper half) and imperial (lower half) units at a given latitude in WGS84 by CMG Lee. For comparison, dotted lines denote corresponding lengths assuming a spherical Earth.
