All; But if I convert the DEM or DSM to geotiff I still wont get back the hit order or the classification values will I? I will just have the data I have as processed in a different format. What I really need is the original LiDAR datasets if I am understanding this correctly. As for DTM, DSM, and DEM, The province my municipality is in has decided that; DTM is a surface model which includes surface features + ground hits + breaklines. A DEM is ground hits, and a DSM as is the surface + features without added breaklines. I have found definitions online to support both view points on the matter; just an FYI my text books agree with you on the matter. I blame AutoCAD/CADD users for the discrepancies because, in my experience according to the EIT's and other CADD users, a DTM is all of the above and a DSM and DEM doesn't exist lol. Thanks for the help on this; Tyler
