TOPOJSON to KTX2 Conversion
What are TOPOJSON files?
TOPOJSON is a compact text format for maps whose areas touch each other, such as countries, states, or districts. It extends GeoJSON with one important idea: instead of writing the outline of every area separately, it writes every shared border only once, and each area then lists the pieces of border it is made of. This removes the duplicate lines between neighbors, so a TopoJSON file is often many times smaller than the same map in GeoJSON, and it also keeps the information about which areas share a border. Because of its small size, the format is popular for maps on web pages, where files have to be downloaded quickly. The files have the .topojson extension, although .json is also used.
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.
