Ich habe einige Probleme mit der Konvertierung von HDF zu GeoTiff.
Ich folge den auf dieser Webseite beschriebenen Schritten . Das Problem ist, dass ich den Namen des NDVI-Subdatensatzes (XXXX) nicht finden kann, um den Befehl gdaltranslate auszuführen.
gdal_translate -of GTiff HDF4_EOS:EOS_GRID:"MOD13C2.A2001001.005.2007078152825.hdf"
:MOD_Grid_monthly_CMG_VI:XXXX modis_ndvi01.tif
Dies ist die gdalinfo-Ausgabe für eine der Dateien (MOD13C2.A2001001.005.2007078152825.hdf):
