Описание тега spatial

Spatial data types store an object's position in space, colloquially these types are "geometric" or "geographic", and operating on them will make use of geodesic or Cartesian calculations. The applied field devoted to spatial data is Geographic Information Systems (GIS); the GIS Stack Exchange should be considered for questions with this tag.

Many popular databases engines now include support of spatial data types, including:

• sql-server - see Spatial Data (SQL Server)
• mysql - see MySQL Spatial Data Types
• postgresql
  • see PostGIS (extension)
  • native geometric types
