FAQ
GVB to DRW Conversion
What are GVB files?
GVB is a datum grid shift file that follows the NTv2 (National Transformation version 2) model, created by the Geodetic Survey of Natural Resources Canada. Such a file helps convert map coordinates between two geodetic datums, which are different mathematical models of the Earth, so that old and new survey data line up correctly. It covers an area with a net of points and stores, for each of them, how far latitude and longitude have to be moved, usually with an estimate of the accuracy of the shift. A program finds the points nearest to a location and calculates the exact correction between them. Files with this structure are used by national mapping agencies and surveyors, and they are particularly valuable for cadastral and engineering work, where small errors matter.
What are DRW files?
DRW stands for "Drawing" and represents a vector graphics format associated primarily with Corel Draw, but also with other advanced graphics design programs, including Microsoft Picture It!, Paint Shop Pro, Micrografx, Igrafx etc. The DRW format is supported both on Windows and Mac applications (on MacDraw and AppleWorks) and stores images and drawings constructed with lines or paths, instead of dots.
