Oracle Spatial is part of the Oracle Database. Through Oracle Spatial, geographic and location data are managed in a native type within an Oracle database providing a platform that supports a wide range of applications—from automated mapping/facilities management and geographic information systems (GIS), to wireless location services and location-enabled e-business.

Oracle Spatial provides a SQL schema and functions that facilitate the storage, retrieval, updatae, and query of collections of spatial features in an Oracle database. Oracle Spatial consists of:

  • A schema that prescribes the storage, syntax, and semantics of supported geometric data types.
  • A spatial indexing system.
  • Operators, functions, and procedures for perfroming area-of-interest queries, spatial join queries, and other spatial analysis operations.
  • Functions and procedures for utility and tuning operations.
  • A topology data model for working with data about nodes, edges, and faces in a topology.
  • A network data model for representing capabilities or objects that are modeled as nodes and links in a network.
  • A GeoRaster feature to store, index, query, analyze, and deliver GeoRaster data, that is raster image and gridded data and its associated metadata.

The spatial component of a spatial feature is the geometric representation of its shape in some coordinate space. This is referred to as its geometry.
