This website is essential for geospatial professionals, GIS developers, and cartographers, providing an extensive database of spatial reference systems used globally
- Spatial reference system - Wikipedia
A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on, or relative to, the surface of Earth as coordinates
- Spatial references—ArcMap | Documentation - Esri
A spatial reference is the coordinate system used to store each feature class and raster dataset, as well as other coordinate properties such as the coordinate resolution for x,y coordinates and optional z- and measure (m)-coordinates
- Spatial referencing and coordinate systems
In mathematics, there are in general two ways to determine a point position in space – that is, by Cartesian coordinates or by angular coordinates The coordinates of the point are normally related to a right-handed rectangular coordinate system, or other combinations

A spatial reference describes where features are located in the real world You define a spatial reference when creating a geodatabase feature dataset or stand-alone feature class

We use a Reference surface (i e datum system) to approximate the shape of the Earth A horizontal datum (also called geodetic datum) is a model used to measure positions on the Earth A Vertical datum is a model used to measure elevations, which is related to the Geoid

Spatial referencing is a foundational concept in computer science that enables the precise specification, indexing, and querying of spatial locations across diverse applications
- Spatial Reference Definition | GIS Dictionary - Esri Support
A spatial reference is used to provide a framework when measuring and representing geographic features from different sources Each spatial reference is defined either by a WKID—also called a spatial reference ID (SRID)—or by a WKT
