Detailed Description

Register digital elevation model (DEM) data into metadata store for a project directory, copying the DEM file into the project directory in the process.

Will create a study area polygon shapefile for the extent of the DEM imported.

Pre conditions

None

Post conditions

1. Will write the following entry(ies) to the manifest section of metadata associated with the project directory: dem [the name of the DEM raster] study_area_shapefile [the name of the study area shapefile generated from the DEM raster extent]

1. Will write the following entry(ies) to the study area section of metadata associated with the project directory: bbox_wgs84 dem_res_x [X resolution of the DEM raster in units of the raster's projection] dem_res_y [Y resolution of the DEM raster in units of the raster's projection] dem_srs [spatial reference system of the DEM, in EPSG:<nnnn> format] dem_columns [number of pixels in the X direction] dem_rows [number of pixels in the Y direction]

Usage:

python ./RegisterDEM.py -p /path/to/project_dir -d /demfile/to/register

Note

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

Todo:

Add targer SRS, if present, call GDAL warp instead of just copying the file

Set date in provenance to file modification date
