filenames, applications, monteverdi or custom C++ code might override

* ``OTB_DEM_DIRECTORY``: Default directory were DEM tiles are stored. It should only contain ```.hgt`` or or georeferenced ``.tif`` files. Empty if not set (no directory set)
* ``OTB_GEOID_FILE``: Default path to the geoid file that will be used to retrieve height of DEM above ellipsoid. Empty if not set (no geoid set)
* ``OTB_MAX_RAM_HINT``: Default maximum memory that OTB should use for processing, in MB. If not set, default value is 128 MB.
* ``OTB_LOGGER_LEVEL``: Default level of logging for OTB. Should be one of ``DEBUG``, ``INFO``, ``WARNING``, ``CRITICAL`` or ``FATAL``, by increasing order of priority.
