Hi, Antonio!
You can do that with the gdalinfo command prior to running a python script:
gdalinfo MODIS_FILE.hdf | grep EV_1KM_RefSB | wc -l
returns a number if subdataset EV_1KM_RefSB exist
return 0 if not.
triton:gdaltest>gdalinfo MYD02QKM.A2010217.1335.005.2010218190207.hdf |
grep EV_1KM_RefSB | wc -l
0
triton:gdaltest>gdalinfo MOD021KM.A2010105.2120.005.2010106075131.hdf |
grep EV_1KM_RefSB | wc -l
7

Greetings
I have a Python Script where I call gdalwarp binary (in Windows) to warp
an image. But, before I run the gdalwarp I need to check if the file
exists (DONE) and if a defined HDF layer exists. How can I check, using
gdal, in a Script if a certain layer exists?
THanks
Antonio
