Waterbody shapefile lacks COMIDs #1

Closed rmfricke closed 5 years ago

rmfricke commented 5 years ago

Need to replace the Waterbody.shp with new raw data source containing COMID field.

We're going to use the national shapefile instead: [http://prd-tnm.s3-website-us-west-2.amazonaws.com/?prefix=StagedProducts/Hydrography/NHD/National/HighResolution/GDB/]

Scratch that, we're building this workflow around NHD v2.1 Waterbody table. NHD v2.1 differs from NHD v2.0 by using "PERMANENT_IDENTIFIER" instead of "COMID". Lakes that existed in v2.0 kept their original (COMID) ID values. This will allow us to join LakeCat data, through LakeCat's COMID field.

NHD 2.1 is available as shapefiles by state or as a national geodatabase. We'll probably loop through the state-level shapefiles, which are at http://prd-tnm.s3-website-us-west-2.amazonaws.com/?prefix=StagedProducts/Hydrography/NHD/State/HighResolution/Shape/
