Hi everyone,
I just created a test terrain with breaklines and I have a couple questions hoping someone has some experience that I'm lacking.
I used only the bare earth returns from our .las files, and building footprint lines (3D with building heights) as hard lines for breaklines.
1. Along the edges of the buildings the terrain slopes drastically from the closest LiDAR point on the ground to the top of the building. This makes sense, but is it possible to create a terrain that will slope from the nearest LiDAR point to the bottom of the building (basically interpolating from the last point to the bottom of the building instead of interpolating from the nearest point to the top of the building).
2. Because of numerous reasons there are areas where some of the bare earth LiDAR points slightly overlap and are on the inside of building footprints (this is not a LiDAR issue, but more of building editing issue where the exact footprint isn't possible to see). When this occurs it really causes issues in the terrain for that building location. Other than breaking up the multipoint features, removing the points that intersect with buildings, then recreating multipoint features, how can I deal with this issue?
