No, that's a separate API. There's a bridge between both with the GDALRasterBand::AsMDArray() and GDALMDArray::AsClassicDataset() methods. The gdalmdimtranslate utility can also bridge between the 2 worlds. That is if you export a 4D array as a GeoTIFF, it will use GDALMDArray::AsClassicDataset() and will expose the non-XY dimensions as many bnds as needed. > Arrays of a single type per dimension, but > that's conventional for N-D array implementations like Numpy. Not sure to understand the above. The data type is the same for a given array. Yes, ala NumPy. > Perhaps the > RFC and feature would be better named "hierarchical data"? This is both actually: hierarchial data + multidimensional arrays.
