FAQ
GML to KTX2 Conversion
What are GML files?
GML (Geography Markup Language) is an XML-based language for describing geographic features, developed by the Open Geospatial Consortium (OGC) and adopted as the international standard ISO 19136. A GML file is readable text in which every object on a map, such as a building, a road, a lake, or a boundary, is written down together with its shape and its attributes, for example a name, a type, or a population. The language is a toolbox rather than a fixed list of objects: communities and organizations define their own application schemas on top of it, which is how national mapping data, cadastral records, and the data of 3D city models are exchanged. GML is also the standard way for web map services to return features.
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.
