FAQ
ERR to PCT Conversion
What are ERR files?
ERR is a file that accompanies Canadian geoid models published by the Canadian Geodetic Survey of Natural Resources Canada (NRCan). While a geoid file stores the height of the geoid above the reference ellipsoid, a file of this type stores the estimated uncertainty of those heights for the same area. It uses the BYN structure, with an 80-byte header and a regular grid of whole numbers, and normally shares its name with the geoid file it describes, for example CGG2013n83.err next to CGG2013n83.byn. Surveyors and geodesists use such grids to judge how reliable a height conversion from GNSS measurements is in a given location. The values are small, because they express the expected error of the model rather than a height.
What are PCT files?
PCT is an image file format associated with Macintosh QuickDraw, a graphics program developed in the 1980s as part of the Apple Macintosh operating system. The initial version of the format, called PICT 1, could store 8 colors, while the later developed PICT 2 supported 24 and 32-bit color images. In recent years, the format has decreased in popularity, being gradually replaced by more versatile formats.
