contained in the ortofotos mosaic. However, orthophotos
mosaic supplied terrain and vegetation covering information
that could not be extracted of LIDAR products.
The difficulty of laser beam in penetrating closed
coverings, together with LIDAR sensor difficulty in defining
natural and artificial breaklines influenced excessively in final
quality of DTM generated from LIDAR points cloud.
The product generated by DSM, orthophotos mosaic
and highway geometric project integration made possible a
high quality visualization of highway project. This product can
be used as much visualization element for customer project
presentation as for public hearings.
Filtering and classification algorithms of LIDAR points were
not sufficiently efficient for present acceptable results through
automatic processes. The manual edition with aid of images
(ortophots mosaic and LIDAR intensity image) it went essential
to increase the filtering and classification quality of LIDAR
points cloud.
