I have a problem when I use the gdal to open the modis Hdf4 file.
when I get the latitude and the Longitude, I do not know how to read it.
is it use GetMetadata( "SUBDATASETS" )?
but the SUBDATASETS, don't include the geolocation information.
in the hdf4 file, ther is a geolocation fields, data fields and swatch attributes.
when I read the data in the data fields, I use GetMetadata( "SUBDATASETS" ).
but I do not know how to read the data in the geolocation fields.
can anyone help me?
