Hi, Michael! It's an interesting idea since Kerchunk can't handle HDF4 yet [1]. OPeNDAP DMR++ now can handle HDF4 so I think Kerchunk can do, too. For GDAL, is there C++ binding for Kerchunk? I think that will be the main blocker for GDAL driver development. [1] https://github.com/hyoklee/kerch

Hi, is there any effort or thought into something like Python's kerchunk in GDAL? (my summary of kerchunk is below) https://github.com/fsspec/kerchunk I'll be exploring the python outputs in detail and looking for hooks into where we might bring some of this tighter into GDAL. This would work

Hi, I've got a chance to have a look at your test dataset. In https://github.com/OSGeo/gdal/pull/10477, I've reduced the runtime to 8 minutes (with GeoParquet output, without spatial sorting), by optimizing some implementation details. I believe this could be further reduced as most of the ti

Javier, I've just advertized bilinear. For average_mp vs average_magphase, they are indeed different code paths. My understanding of the code is that: - average_magphase is only available for the complex data types - for the complex data types, average_magphase makes sure that the norm of th
