[gdal-dev] Want to work with MDArrays

[Laurențiu Nicola]

Hi Barry,

I think you want GDAL_OF_MULTIDIM_RASTER. There's an example here: https://gdal.org/tutorials/multidimensional_api_tut.html.

I sometimes write importer libraries to pull data into my data structures for further processing. It is primarily a package for scientists.

It is using gdal.Open(filename) to load data as a Dataset but I think the approach taken is limited to 3-d data. Plus testing has shown that sometimes (like with a tif stack) images come in as many separate planes of data.

That way I could then open one or more MDArrays into my n-dimensional structures from the Group in a more direct fashion than the Dataset way. Can you advise me on how to proceed? Thanks.
