The code above shows that there are two sections of information to add. One is to identify the
correct CoreEngine dll and version number

1

, the second is to add elements for EPSG and SRID

code mappings.

An EPSG code mapping consists of an SRSName, SRS ID, and EPSG code(s). The SRSID is
further defined by the parameters and codespace for the coordinate system.

An SRID code mapping is similar to the EPSG code mapping, except it refers to the Oracle Spatial
identification number.

For more information on coordinate systems, see

Appendix H: Elements of a Coordinate System

.

For information on the MapInfo codespace, see

Appendix G: Defining the MapInfo Codespace

.

To determine the correct version number for the MapInfo.CoreEngine assembly, from the Start menu,
choose Run and type Assembly in the Run dialog. Every registered MapXtreme assembly is listed in the
global assembly cache list.
