Selecting or creating coordinate systems

One of the first steps in planning a project is to determine what coordinate system to use.

Before you begin

Before you create a coordinate system, your user ID must have either SYSADM or DBADM authority on the database that contains the spatial catalog tables.

About this task

After you enable the Db2 subsystem for spatial operations, you are ready to plan projects that use spatial data. You can use a coordinate system that is included with IBM® Spatial Support for Db2 for z/OS® or one that was created elsewhere. Many coordinate systems are included with IBM Spatial Support for Db2 for z/OS.

To find out about these coordinate systems, and to determine what other coordinate systems are included with IBM Spatial Support for Db2 for z/OS, and what (if any) coordinate systems have been created by other users, consult the DB2GSE.ST_COORDINATE_SYSTEMS catalog view.

Procedure

To create a coordinate system:

Run an application that invokes the ST_create_coordsys stored procedure.
For more information about this stored procedure, see ST_create_coordsys.
