DEM Clipper

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 data. 

• Ground-truthing GPS collected data
• Ground-truthing elevation data collected with traditional surveying methods. 
• 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.
