Spatial functions: categories and uses

This information introduces all of the spatial functions that IBM® Spatial Support for Db2 for z/OS® provides, organizing them by category.

IBM Spatial Support for Db2 for z/OS provides functions that:
  • Convert geometries to and from various data exchange formats. These functions are called constructor functions.
  • Compare geometries for boundaries, intersections, and other information. These functions are called comparison functions.
  • Return information about properties of geometries, such as coordinates and measures within geometries, relationships between geometries, and boundary and other information.
  • Generate new geometries from existing geometries.
  • Measure the shortest distance between points in geometries.
  • Provide information about index parameters.
  • Provide projections and conversions between different coordinate systems.
