FAQ
GTX to HPG 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 HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
