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

State Planes in the United States (with their Datums). Unsupported State Planes

will be noted in this section.
