LiDAR technology, however, does not inherently collect the breaklines necessary to
produce traditional DTMs. Breaklines have to be developed separately through a
variety of techniques, and either used with the LiDAR points in the generation of the
DTM, or applied as a correction to DTMs generated without breaklines.
Mobile Mapping and Stationary Scans datasets are highly accurate. Breaklines from Mobile Mapping and Stationary Scanning are extracted in post processing. However breaklines from Conventional Survey methods are ready for use.
