Not sure what prefix to use, but this is about LIDAR data showing up on my map. My map will have tracks from Ivy City Yard in DC to Broad Run. This will be for the VRE Manassas line. I created the map and added in the basic HGT files for terrain, but for where my tracks are I need the more precise LIDAR data. Everything but applying the LIDAR seems to be working fine. I created the .asc files for the lidar by converting the .tif files that were cut into the small sections. I believe I've checked that the .asc files show up in the right spots, and are linked as the LIDAR source in the Route Building Mode. When I go to the Select Mode and click on each tile to apply the LIDAR, the files for the tiles need to be resaved, but there is no difference that I can see and I've tried it all over the map.
