Introduction of processing logic

I build a huc12 navigation table which is saved in the geodatabase.I also have a tool that builds HUC8 to HUC8 navigation based on the HUC12 table.

My overall tool used for the NWIS project uses a loop to aggregate all HUC12s in the current HUC8, then I bring in any upstream HUC8s and dissolve. This is much faster for large basins, of course!


WBD Tools

Output table

  • I don't want to share a table as the WBD is kind of in process, though it's available from me on request.
