Adapt this OCC NWM notebook to read zarr and NHD web services #7

Open rsignell-usgs opened 6 years ago

I'm here in DC at the NOAA Environmental Management Meeting, where @zflamig gave a nice presentation of the Open Commons Consortium's work on the National Water Model data. He showed this notebook which brings in the vector data necessary to marry with the NWM output to make maps: https://github.com/occ-data/nwm-jupyter/blob/master/NWM.ipynb

I think it would be cool to rewrite the data ingest part of this to read NWM data via Zarr.

@dblodgett-usgs, is there a way to obtain the NHD vector data using services?

dblodgett-usgs commented 6 years ago

There are some services around that could get close, but nothing ready for prime time that includes the attributes and filtering that's done in the notebook. The NLDI gets some of what's needed. https://owi.usgs.gov/blog/nldi-intro/ but it doesn't do the attributes or thinning by drainage area.

It might be interesting to load the shapefiles into Postgres/PostGIS and query them that way? Then you could do the sort of dynamic queries...
