Expanding results to NHD polygons #10

Open ChristopherTracey opened 7 years ago

ChristopherTracey commented 7 years ago

For display of the results for some mapping applications, it would be good to have the results mapped to the NHD waterbody polygons instead of the flowlines.

I think the way to solve this is something along the lines of:

  1. In ArcGIS,generate a perpendicular line of length x at the start and end nodes of each artificial path (see the figure below).
  2. Cut the NHD waterbody layer by this line and assign the relevant COMID value to it.
  3. Join up the results in R within the scripts.

@memoore, do you think you can take a shot at this?
