Pre conditions

1. Configuration file must define the following sections and values: 'GRASS', 'GISBASE'
2. The following metadata entry(ies) must be present in the RHESSys section of the metadata associated with the project directory: grass_dbase grass_location grass_mapset rhessys_dir

Post conditions

1. Will write the following entry(ies) to the RHESSys section of metadata associated with the project directory: basestations_text
2. Will write the following entry(ies) to the GRASS section of metadata associated with the project directory: basestations_rast

Usage:

GenerateBaseStationMap.py -p /path/to/project_dir -b /path/to/base/station/file

Note

GRASS v.voronoi routine used to generate Thiessen polygons has difficulties when there are only two points. This may be fixed in GRASS 6.4.3. Until then, do not use two climate stations.

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