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.
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 ...
Geodetic coordinates P(ɸ,λ,h). Geodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid.They include geodetic latitude (north/south) ϕ, longitude (east/west) λ, and ellipsoidal height h (also known as geodetic height [1]).
It was then formally called WGS 84 (G873). WGS 84 (G873) was adopted as the reference frame for broadcast orbits on January 29, 1997. [9] Another update brought it to WGS 84 (G1674). The WGS 84 datum, within two meters of the NAD 83 datum used in North America, is the only world referencing system in place today.
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 ...
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.
