Finally, be aware that although DelphMap can export only certain DDS
projections to GeoTIFF, DelphMap can always export to TIFF. You use the
information from the Projection Information dialog box to specify resolution, X-Y
limits, etc. Additionally, whenever a GeoTIFF or TIFF file is exported from
DelphMap, a world file is created. See “Mapping Geo-Coordinates to Images”.
Supported GeoTIFF Projections
DelphMap supports Universal Transverse Mercator (UTM) projections having
certain Datums, certain Lambert projections (with all Datums), and nearly all
