Coastal data viewer

I want three layers, might not use all of them in the final product.

  1. contours
  2. chevrons
  3. terrain shading

Generating contours

Steepness chevrons

  1. Road indicates area of interest
  2. Slope indicates number of chevrons
  3. Aspect indicates direction

so...

  1. build polygons around road
  2. build slope layer
  3. intersect road poly + slope poly
  4. classify slope of each road poly
  5. classify aspect of each poly
  6. place chevrons on center of road segment in each poly
