Breaklines and Features
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.
