6 Coordinate Systems (Spatial Reference Systems)

This chapter describes in greater detail the Oracle Spatial and Graph coordinate system support, which was introduced in Coordinate System. You can store and manipulate SDO_GEOMETRY objects in a variety of coordinate systems.

For reference information about coordinate system transformation functions and procedures in the MDSYS.SDO_CS package, see SDO_CS Package (Coordinate System Transformation) .
