MEM to KTX2 Conversion
What are MEM files?
MEM is the file extension of a digital elevation model of Japan produced by the Geographical Survey Institute of Japan, now the Geospatial Information Authority of Japan (GSI), the national mapping agency. A file of this type covers a part of the country with a regular net of points, and each point holds the height of the ground above the Japanese vertical reference, which is based on the mean sea level of Tokyo Bay. The data were derived from the topographic maps of the Institute, and the older series came with grid spacings such as 50 meters. Coordinates are given in latitude and longitude on the Tokyo datum, the national system that was in use before the switch to modern satellite-based systems. Such files are used for terrain analysis, mapping, and visualization of Japan.
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.
