FAQ
GTX to IFF Conversion
What are GTX files?
GTX is a grid file used by NOAA's VDatum software to convert heights from one vertical reference to another. Heights on maps can be measured from different surfaces, such as the ellipsoid used by satellite positioning, the geoid that approximates mean sea level, or a tidal level like mean lower low water, and the difference between these surfaces changes from place to place. A file of this type covers an area with a regular net of points and stores the height difference at each of them, so that a program can add it to a measured height and obtain the value in the other system. Earlier versions were text files, while current ones are binary. The format is also used for global geoid models and for national height transformations.
What are IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
