J'ai des problèmes avec la conversion de HDF en GeoTiff.
Je suis les étapes décrites dans cette page Web . Le problème est que je ne trouve pas le nom du sous-jeu de données NDVI (XXXX) pour exécuter la commande gdaltranslate.
gdal_translate -of GTiff HDF4_EOS:EOS_GRID:"MOD13C2.A2001001.005.2007078152825.hdf"
:MOD_Grid_monthly_CMG_VI:XXXX modis_ndvi01.tif
Il s'agit de la sortie gdalinfo pour l'un des fichiers (MOD13C2.A2001001.005.2007078152825.hdf):

Réponses:
Je pense que vous l'avez presque. Assurez-vous d'ajouter des guillemets simples autour du nom d'entrée complet avec des guillemets doubles autour du nom du fichier hdf.
J'espère que ça t'as aidé
