I am using the LDOPE mask_sds tool to mask a MODIS image based on the quality flags for MOD13A3 NDVI. The full command that I am using is:
mask_sds -of=mask.hdf -fill=-3000 -sds='1km monthly NDVI' -mask="MOD13A3.A2000336.h25v02.005.2007112105435.hdf,'1km monthly VI Quality',0-1==00,AND,*,*,11-13==001" -meta MOD13A3.A2000336.h25v02.005.2007112105435.hdf
I am getting the following error:
Cannot find the SDS '1km monthly VI Quality' Ignoring input masking option MOD13A3.A2000336.h25v02.005.2007112105435.hdf,'1km monthly VI Quality',0-1==00,AND Cannot open the input HDF file * Cannot open the HDF file * Ignoring input masking option *,*,11-13==001 usage: mask_sds -help [filename] mask_sds -of=<output filename> -sds=<SDSname1>[,<SDSname2>[,...]]> [-fill=<mask fill value>] -mask=<mask1>[,AND|OR,<mask2>[,...]] [-meta] filename where maskn=< filename>,<SDSname>,<bit_numbers operator bit_values>
It looks like it can not find the SDS (science data set) for the quality flag. I have tried several variations of '1km monthly VI Quality', including without quotes. This website lists SDS's for each MODIS product (I am using MOD13A3).
I would appreciate any suggestions.
Thank you, Kevin
