Definition

A geometry in Oracle Spatial can be one of the followingFootnote 1:

  • Point

  • Linestring connecting two or more points

  • Polygon specified as a closed linestring and indicating an area bounded by the linestring (with zero or more holes inside the outer bounding linestring)

  • Multipoint collection

  • Multiline collection consisting of unconnected linestrings

  • Multipolygon collection consisting of nonoverlapping polygons, or

  • Heterogeneous collection consisting of a mixture of point, linestring, and/or polygon geometries

Each geometry can be specified in the context of a spatial reference system, also referred to as a coordinate system. Typical coordinate systems are local or geographic. Geographic coordinate systems are geodetic or projected. Whereas local and...
