Pre conditions

1. Configuration file must define the following sections and values: 'GDAL/OGR', 'PATH_OF_GDAL_RASTERIZE'
2. The following metadata entry(ies) must be present in the manifest section of the metadata associated with the project directory: soil_features [the name of the vector file containing the soil features]
3. The following metadata entry(ies) must be present in the study area section of the metadata associated with the project directory: dem_res_x dem_res_y

Post conditions

1. Will write the following entry(ies) to the manifest section of metadata associated with the project directory: soil_raster_<attr> [the name of the raster file for each soil property raster]

Usage:

GenerateSoilPropertyRastersFromSSURGO.py -p /path/to/project_dir

Note

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