This Windows application converts geographic coordinates between any pair of nine systems; latitude and longitude as well as different grid and map projection systems. The grid systems supported are Township and Range, British Columbia's NTS-based grid system,the Canada Lands system, the UTM system, and the UTM-based Military system. The projections supported are Mercator, Lambert and Polyconic. Transformations can be done in either the NAD27 or NAD83 datums (NAD27 only for Township and Range), but not between datums. To use the tool the user enters alocation and defines its coordinates system on the input source screen, defines the desired output system on the output destination screen, and selects the find button. The application then calculates the location in the new destination system. The application is a Delphi (Trade Mark) run-timemodule for Windows 95/98.
