North Carolina coast LiDAR

Short title: 
NCLiDAR

This dataset contains a series of x,y,z LiDAR point cloud data in csv format, delimited by comma. Points are projected in the NC State Plane EPSG 3358 coordinate system with units meters.

To get more better representation of structures from LiDAR surveys,
re-interpolate to 0.3-0.5m resolution using the available external point clouds nc_coast_pointseries.zip (34).

Lineage: 

All other data sets are from lidar, but the coverage varies, some data sets cover only beach and foredune area and do not include the main dune. Date of the surveys is in the name of of the file in the form YYYY_MM_DD.

To view the point cloud and photos visit photosynth.

If you use google you will find instructions on how to extract the point cloud. This is a great tool for quick elevation data capture for small features.
