Choose Coordinate System Dialog

This dialog is used to:

• Set the projected coordinate system for the GeoPlan. It is displayed when you click in the Select Coordinate System dialog. See Selecting the Coordinate System for details.

  Note: Although the coordinate system list for a MapXtreme map control includes 'Longitude and Latitude' options, these are geographic not projected coordinate systems and therefore should not be selected for use in InfoWorks ICM.

• Change the coordinate system for a shape file layer. It is displayed when you click in the GIS Layer Control dialog, and lets you change the coordinate system for a shape file. See below for details.
