North Carolina coast LiDAR

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 (77).

Available layers: 

  • “JR_NED_*” – 1/3 and 1/9-Arc Second National Elevation Dataset (2 m);
  • “ortho_JR_*” – Time series of ortho photos (1932, 1945, 1955, 1974, 1988, 1998, 2007, 2009);
  • “JR_*.csv” – Time series of point clouds from LiDAR (1974, 1995, 1996, 1997, 1998, 1999, 2001, 2005, 2007, 2008, 2009)

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.
