Pre conditions

1. Configuration file must define the following sections and values: 'GRASS', 'GISBASE' 'GRASS', 'MODULE_PATH'
2. The following metadata entry(ies) must be present in the manifest section of the metadata associated with the project directory: dem
3. The following metadata entry(ies) must be present in the study area section of the metadata associated with the project directory: dem_srs

Post conditions

1. Will write the following entry(ies) to the RHESSys section of metadata associated with the project directory: grass_dbase grass_location grass_mapset rhessys_dir model_description
2. GRASS location and mapset will be created in grass_dbase
3. Will write the following entry(ies) to the GRASS section of metadata associated with the project directory: dem_rast

Usage:

CreateGRASSLocationFromDEM.py -p /path/to/project_dir -script GRASSData -l default -m "Grass location for RHESSys model of Dead Run watershed in Baltimore, MD"

Note

EcoHydroWorkflowLib configuration file must be specified by environmental variable 'ECOHYDROWORKFLOW_CFG', or -i option must be specified.
