This template is designed to convert a set of Swiss coordinates into either the corresponding WGS84 decimal latitude or longitude. It is intended to facilitate the usage of geodata (see {{ coord }} ) in articles about subjects for which only Swiss coordinates are readily available.
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.
EPSG:3857 - Web Mercator projection of WGS 84, used for display by many web-based mapping tools, including Google Maps and OpenStreetMap. EPSG:9989 - International Terrestrial Reference Frame 2020 (ITRF2020) for 3D coordinates (latitude, longitude, ellipsoidal height) with subcentimeter accuracy, used for monitoring continental drift among others.
ISO 6709, Standard representation of geographic point location by coordinates, is the international standard for representation of latitude, longitude and altitude for geographic point locations.
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]
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame, or terrestrial reference frame) is a global datum reference or reference frame for unambiguously representing the position of locations on Earth by means of either geodetic coordinates (and related vertical coordinates) or geocentric coordinates. [1]
On 7 January 2024 move to IGS20 happened, so WGS 84 is now aligned with ITRF2020, including PSD (post-seismic deformation), also called G2296. On the other hand GLONASS is using PZ-90.11, which is close to ITRF2008 at epoch 2011.0 and is using 2010.0 epoch (that means when you use reference transformation to PZ-90.11 you will get January 2010 ...
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.
