I am trying to figure out how I can create projected future coastlines by intersecting an elevated polygon (representing future sea level) with the TIN/DEM of my study area.

Does anybody know how I could accomplish this?

Ideally, I'd like to create a polyline feature where the elevated polygon intersects with my surface model.

I am using ArcMap 10.8

  • Generate contours of the future sea levels using your surface model and the contour list tool. desktop.arcgis.com/en/arcmap/latest/tools/…

  • That was an even simpler solution than I thought, thank you that should work perfectly!
