I have used LAStools from rapidlasso and found their software extremely useful. However, while I have not attempted this type of processing using rapidlasso programs I have done so using ArcGIS. The results are astounding: [cid:image006.jpg@01CFFCC9.A3082600] In the above image (black = no change between DTM and DSM; and white = a "significant" change between DTM and DSM) we can readily discern individual trees and tree lines as well as buildings and other features. Moreover, I would venture we could also accurately identify softwood vs. hardwood stands and many other entities! We can also overlay a Maine Office of GIS orthophoto on the "canopy height model" and, to me, it appears to give some "depth" to an otherwise flat image. What do you think?

It exceeds my level of competence but some of you may find it useful in determining tree canopy heights. http://rapidlasso.com/2014/11/04/rasterizing-perfect-canopy-height-models-from-lidar/ Joseph Young Executive Director Maine GeoLibrary SHS 145 51 Commerce Drive Augusta, Maine 04333- 145 VP 207-624-2664 FAX 207-287-1131 [MaineGeoLibrary_Web_banner_JY]<http://lists.maine.edu/cgi/wa?A0=geolibrary-l> Subscribe to our List Serve<http://lists.maine.edu/cgi/wa?A0=geolibrary-l> learn more about the GeoLibrary http://lists.maine.edu/cgi/wa?A0=geolibrary-l ----------------------------------------------------------------------- This list Maine GeoNews (GEOLIBRARY-L) is an unmoderated discussion list for all Maine GIS Users.
