Catalog views

The catalog views in IBM® Spatial Support for Db2 for z/OS® give useful information.

Catalog views contain information about:
  • Coordinate systems that you can use
  • Spatial columns that you can populate or update
  • Allowable maximum lengths of values that you can assign to variables
  • Spatial reference systems that you can use
  • The units of measure (meters, miles, feet, and so on) in which distances generated by spatial functions can be expressed
