Thanks for that, Even, looks good! I have a couple of questions:
- what would be the advantage to GDAL users using this interface, as opposed to reading/writing directly using the HDF or NetCDF4 interfaces? Will it for instance be able to figure out coordinate reference systems, and identify which dimensions are spatial dimensions? - will this interface also give access to e.g. irregular dimensions (for rectlinear grids), bounds of dimensions, or two-dimensional dimension values like longitude values for each grid cell (for curvilinear grids)? - will handling of time values follow the netcdf pattern (e.g. integer values, along with a udunits2 time unit), or be like a double representing seconds since 1970-01-01, or be something more higher level like it is in OGR's OFTDateTime? - will it also be possible to read e.g. spatial raster bands on a lower than native spatial resolution, like RasterIO() does?
