I'm new to python and how it can be applied to gis. I have a large amount of MODIS files to go through and I've already extracted, reprojected and converted to GTiff the bands that I need from each HDF file using convertModisGDAL from pymodis.

Now I need to mosaic pairs of this file list. More specifically, I have this kind of files and I need to merge the h24's with the h25's:

MOD11A2.A2000065.h24v04.005.2007176173328_LST_Day_1km.tiff MOD11A2.A2000065.h25v04.005.2007176173328_LST_Day_1km.tiff

MOD11A2.A2000065.h24v04.005.2007176173328_QC_Day.tiff MOD11A2.A2000065.h25v04.005.2007176173328_QC_Day.tiff

Do you have any suggestions on how can I accomplish this with gdal_merge?

I was trying to do so something with this but I have not been very successful:

for root, dirs, files in os.walk(inputFolder):

    for hdf24 in fnmatch.filter(files,pattern_24):
        p1 = os.path.realpath(os.path.join(root,hdf24))

    for hdf25 in fnmatch.filter(files,pattern_25):
        p2 = os.path.realpath(os.path.join(root,hdf25))

    sys.argv = ['-o','outputTif12','-of','GTiff','-ot','Float64','-n','0','-a_nodata', '-9999', p1, p2]
    gdal_merge.main()
  • Please explain what about your code makes it "not been very successful". – bugmenot123 Apr 15 '17 at 13:11
