Hi: Maptitude stores the locations of map features in degrees of longitude and latitude. However, Maptitude can import and export the locations of map features in many other coordinate systems, including State Plane Coordinates, Universal Transverse Mercator (UTM), and others.
If your Shapefile does not have a *.prj file associated with it, then you must determine the projection from any supplied metadata for the Shapefile, or from the organization supplying the Shapefile.
