FAQ
GSB to JP2 Conversion
What are GSB files?
GSB (Grid Shift Binary) is the file extension of the NTv2 format, short for National Transformation version 2, developed in Canada by Natural Resources Canada for converting map coordinates from one geodetic datum to another. When old maps were based on one model of the Earth and new surveys use another, the same place ends up with slightly different coordinates, and a file of this type records how far each point has to move. It covers an area with a net of points and stores the shift in latitude and longitude at each of them, usually together with an estimate of the accuracy. The format later spread to other countries, including the United Kingdom, Switzerland, and Australia, and it is widely used in surveying, cadastre, and GIS.
What are JP2 files?
JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
