I'm using ArcGIS 10 and Windows 7.
I have built a terrain from a single LAS file with 34 million points of combined TLS and ALS.
I created a DTM using the Terrain to Raster tool at 0.2m resolution.
I get these strange lines in the DTM (see Snapshot1). I have checked the points and terrain and they look fine.
I tried the Terrain to Raster tool at different resolutions yet the lines still appear at the same locations.
I notice the lines only appear at areas with ALS points.
The artifacts are causing problems to my slope and ArcHydro results.
Has anyone encountered similar problem?
Jon
