Utilities used to extract metadata that links National Water Model (NWM) feature identifiers to United States Geological Survey (USGS) site codes.
Running make in this directory will build the required Python environment, retrieve raw NetCDF Routelink files from NCEP and convert them to CSV. This creates two new directories: netcdf which will contain the raw NetCDF files and csv which will contain a CSV equivalent to each file in netcdf. You can view a list of the file URLs retrieved in files.txt. Actual Python code is in scripts. The default make target will generate a RouteLinks.tar.gz which contains all the csv files and a RouteLink.h5 that contains all the data in a pandas.DataFrame.
Running make clean will remove the intermediate files. Running make all-clean will remove the final files and the intermediate files.
If you found this resource on HydroShare, you just need to download one of the final files (RouteLinks.tar.gz or RouteLink.h5).
