FAQ
GTX to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
