hi,all 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? best regards.
