FAQ
SG-GRD-Z to KTX2 Conversion
What are SG-GRD-Z files?
SG-GRD-Z is a compressed grid file of SAGA GIS, a free, open-source geographic information system used for terrain analysis, hydrology, soil science, and climate studies. A grid is a map made of equal cells with one value in each, such as an elevation model. The older SAGA format keeps such a grid in several separate files: one with the values, one with the description, and often one with the projection. A file with this extension packs all of them into a single archive, which is more convenient to store, copy, and send, and which takes less space because the data are compressed. The archive can be opened in SAGA GIS like an ordinary grid, without unpacking it by hand.
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.
