Datum Transformation

This is a drop-down list that matches the list currently shown on the Main Form.

    • To remove an item from the list, select the Remove button. When an item is removed from the list, the grids still reside within the program and can be added back later if needed.
    • To add an item to the list, click the New button. You will then type the name of the added transformation into the transformation Description field.

    Note: To be included in the dropdown list, a Datum Transformation must have a valid pair of “Conversion Grid” files available to the application. These are a matched set of files containing identical prefixes, one with a “.las” extension (latitudes) and the other with a “.los” extension (longitudes).
