File Formats

Geocalc supports a wide range of ASCII text coordinate formats for import and export. Coordinates can be expressed as Latitudes and Longitudes, Easting and Northing or X,Y,Z. The following coordinate file formats are predefined:

  • Geocomp Spatial Data System (.PTS & .STR)
  • Geocomp Field File (.FLD)
  • GeoNav Coast File (.CST)
  • UKOOA P1/90
  • X Y Z

GeoCalc 4.20 is an ideal companion for Geocomp, GeoNav, or any other point-based spatial data system.
