Adding a Best Fit Coordinate system to Geocalc.dat

 
The Best Fit coordinate system will be added to the Geocalc.dat in the same manner that any custom coordinate system is added. First click Coordinate Systems definition in the Options file menu. This will display the Coordinate Systems Definition dialog. If you do not already have a custom coordinate system group, you can create a new one using the New Group button. Use the New System button to add you custom coordinate system. The Datum should be set to the Datum used in the .csr file. If the .csr file was created using the Geographic Calculator, this should be set to WGS84. The Linear Units should be set to the units used in the Local Coordinate system. The Projection should be set to RSF Polynomial. When the Projection is selected, two fields should appear at the bottom of the dialog, CSR File, and Local Units. The Local Units should also be set to the uniots used in the Local Coordinate System. Click on the file open button (...) and browse to the location of your .csr file. Once these fields are filled, click on the Save button to update the Geocalc.dat file.
