In 1911, these different networks on different datums and with different origins were consolidated into one nationwide network and the Luzon Datum was established with triangulation station Balanacan as its datum origin. The Luzon Datum became the primary geodetic reference of all surveys in the Philippines. [1] [2] [3]
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).
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.
OpenLR is a royalty-free open standard for "procedures and formats for the encoding, transmission, and decoding of local data irrespective of the map" developed by TomTom. ...
As a result, the Swiss Federal Office of Topography decided to launch a new land survey campaign in 1988, with the intention of gathering precise data for the development of a new coordinate system based on WGS84.
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
It was probably carried out by the Abteilung für Luftbildwesen (Department for Aerial Photography). From 1947 onward the US Army employed a very similar system, but with the now-standard 0.9996 scale factor at the central meridian as opposed to the German 1.0. [4] For areas within the contiguous United States the Clarke Ellipsoid of 1866 [5 ...
