FAQ
ERR to OBJ 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 OBJ files?
OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
