A generic scriptable Python client for downloading datasets from the USGS/EPA Water Quality Portal: an alternative to manual use of the website at http://www.waterqualitydata.us.
The project consists of the following components:
- a client script,
pywqp-client.py, which obtains WQP data in native Water Quality XML and (if desired) stashes the result on the file system - a pandas import utility,
pywqp-pandas.py, which converts downloaded datasets into pandas data - a parameter validation module,
pywqp_validator.py, which is the sole source of validation logic for WQP's somewhat pretzelesque API - a convenience wrapper,
pywqp.py, which manages common query-and-convert actions. When it is invoked, the commandline parameters control the URL parameters sent to WQP.
