FAQ
ERR to KTX2 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 KTX2 files?
KTX2 (Khronos Texture 2.0) is a container file format for GPU-ready texture data, published by the Khronos Group as the successor to the original KTX format. A single file can hold 1D, 2D, 3D, cubemap and array textures together with their full mipmap chains, stored in the memory layout expected by graphics APIs such as Vulkan, OpenGL and OpenGL ES, so the contents can be uploaded to the video card with little or no additional processing. Besides plain block-compressed data, KTX2 supports supercompression: Basis Universal (ETC1S and UASTC) allows one file to be transcoded at load time into the format the target device actually needs, while Zstandard and ZLIB simply reduce file size. The format is the texture payload used by the glTF KHR_texture_basisu extension, which makes it common in 3D assets for the web, game engines and AR applications.
Can reaConverter convert ERR to KTX2?
Yes! reaConverter instantly converts .err to .ktx2 with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.
What is reaConverter used for?
reaConverter is a Windows converter for 800+ formats, GIS data among them. For ERR to KTX2 it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.
Why choose offline conversion with reaConverter?
reaConverter is a software program that is used for offline files conversion. Your proprietary documents never leave your computer – essential for architects, engineers, healthcare and government contractors handling classified projects. Meets GDPR, HIPAA, CCPA, and corporate security policies by ensuring files never cross borders or third-party systems.
