I am working on a project on sea level rise impacts of roads. Basically I need to determine length of roads that fall under low elevation (from 1m to 5m elevation).
I have a DEM file and road shapefile. I first converted DEM to integer and then raster to polygon. Then I tried to intersect my polygon with polyline but got error as output.
If I am going wrong somewhere can you suggest an alternative way of doing such analysis?
