FAQ
GRI to GLTF Conversion
What are GRI files?
GRI is the data file of the native raster format of the raster package for the R programming environment, which is widely used for statistics and spatial analysis. It holds the cell values of a map or a satellite image as a plain sequence of numbers, without compression, and it is always accompanied by a small text file with the same name and the .grd extension. The text file describes what the numbers mean: the size of the grid, the area it covers, the coordinate system, the type of values, and the names of the layers. Neither file can be used alone. The format is simple and flexible, so it is convenient for saving intermediate results, such as terrain models, climate layers, or land cover maps, when working in R.
What are GLTF files?
glTF or GL Transmission Format is a vector extension developed by the non-profit consortium Khronos with the aim of improving interoperability between various types of software specialized in creating and accessing 3D content. The extension is compatible with several application programming interfaces (APIs) that offer 2D and 3D vector graphics rendering, including WebGL, OpenGL ES and OpenGL.
