I am post processing Terrestrial LiDAR data using RiScan pro and I need to export the data as LAS for use in Arc 10.1 to create a DEM. When I try to use the LAS to Multipoint the file converts but there is no information in the .shp file that it creates. I know that the LAS has information due to its size (1 scan converted to a LAS is a 520MB file). Can anyone help me with what I might be missing?
