DEM Clipper is a program that makes it
easier to work with the NC Floodplain lidar
data. The lidar data for any particular
county consists of hundreds of data files.
Each data file consists of hundreds of
thousands of XYZ points. Finding and
clipping the data for an individual parcel
within a county is awkward at best using the
typical software tools available. DEM
Clipper lets you clip portions of a county's
lidar, creating an ASCII XYZ file suitable
to be imported into most any TIN based
program. DEM Clipper works with either the
bare earth data or the ESRI Grid data.
The principal purpose of DEM Clipper is to
save time and frustration in obtaining the
elevation data for a specific parcel or area
from the vast amount of lidar data
While lidar data may be no substitute for
field collected elevation data it can still
be useful to the surveyor, planner or
engineer in many circumstances. Following
are just a few of the applications for lidar
- Ground-truthing GPS collected data
- Ground-truthing elevation data
collected with traditional surveying
- Supplementing field collected
topographic data with lidar topographic
data in non-critical areas.
- Creating topographic maps for
preliminary planning purposes.
- Confirming the elevation data
collected in the course of collecting
data for FEMA Elevation Certificates.
- Basis for watershed and erosion
control base elevation data.
