class aws.osml.gdal.gdal_config.GDALConfigEnv(options: Dict | None = None)[source]

Bases: object

This class provides a way to setup a temporary GDAL environment using Python’s “with” statement. GDAL configuration options will be set inside the scope of the with statement and then reverted to previously set values on exit. This will commonly be used to set AWS security credentials (e.g. AWS_SECRET_ACCESS_KEY) for use by other GDAL operations.

See: https://gdal.org/user/configoptions.html#gdal-configuration-file for additional options.
