Can I make customized geographic projections using GeoTIFF?
The GeoTIFF spec contains fields for definition of projection variables in 20 different coordinate transformation systems (such as Lambert Conformal Conic, Albers Equal Area, Transverse Mercator, etc). The datums and ellipsoids supported by POSC are all available, as well as limited support for most custom datums and ellipsoids. The GeoTIFF format provides rules, fields, and “cookbooks” for defining customized cartographic spaces if you need them. Since they will be coded as “User Defined” in some fields, not all GeoTIFF readers will be able to understand all possibilities.
