Spatial reference system
Lua error in package.lua at line 80: module 'strict' not found. A spatial reference system (SRS) or coordinate reference system (CRS) is a coordinate-based local, regional or global system used to locate geographical entities. A spatial reference system defines a specific map projection, as well as transformations between different spatial reference systems. Spatial reference systems are defined by the OGC's Simple feature access using well-known text, and support has been implemented by several standards-based geographic information systems. Spatial reference systems can be referred to using a SRID integer, including EPSG codes defined by the International Association of Oil and Gas Producers.
Some systems are:
- Universal Transverse Mercator coordinate system
- British national grid reference system
- Hellenic Geodetic Reference System 1987
- Irish grid reference system
- Irish Transverse Mercator
- Israeli Transverse Mercator
- Israeli Cassini Soldner
- Jordan Transverse Mercator
- Lambert conformal conic projection
- International mapcode system
- Military grid reference system
- United States National Grid
It is specified in ISO 19111:2007 Geographic information—Spatial referencing by coordinates, also published as OGC Abstract Specification, Topic 2: Spatial referencing by coordinate.[1]
