LiDAR and Related Data Products

Small image of Marion Terrain Data Set Lidar data is remotely sensed high-resolution elevation data collected by an airborne collection platform. Using a combination of laser range finding, GPS positioning and inertial measurement technologies, lidar instruments are able to make highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures and vegetation.

Technical Specifications include 1.4 meter nominal point spacing for LAS and Bare-earth, 18.5 cm vertical RMSE to support 2-foot contours, 1.0 meter horizontal RMSE, and accuracy tested at 95 percent confidence level.

Deliverable products include: LAS point cloud data, ESRI File GeoDatabase with Terrain Surface, Intensity Images, 3-D Hydro Breaklines, and quality assurance report. LAS and Intensity image data was divided into 5000' x 5000' tiles and named based on the 1:2,400 index used by the SC Geodetic Survey for County Orthophotos in South Carolina. The Terrain and 3-D Hydro Breaklines are county-wide data sets.

Project Partners

These data products are made possible by the South Carolina LiDAR Consortium comprised of numerous State, Federal, and Local government entities in South Carolina through monetary contributions and in-kind services.

Viewing Data

To view the ESRI File GeoDatabase and tiff data sets you will need computer mapping software. A free viewer from ESRI is available ArcExplorer. The TatukGIS Viewer is a free viewer available from TatukGIS. ArcGIS users will need to install an extension like the free utility LAS Reader for ArcGIS by GeoCue to read the LAS file format or convert the LAS file to a feature using 3D Analyst Tool, LAS to Multipoint.

For other software programs, please consult your particular software's help to determine compatibility with these formats and any required software updates and/or plugins.
