The coordinate systems available for use in IMSMA are managed using the Coordinate System Manager window. The available coordinate systems from installation are the standard ESRI's projections. Copy custom coordinate system projection files to appropriate folder in ''C:\IMSMAng\server\gis\coordinate systems''.
From In the '''Customisation ''' menu, select → '''Coordinate System Manager ''' to display the window.
