2010 USACE NCMP Topobathy Lidar: Atlantic Coast (NC, SC, GA, FL)

These files contain topographic and bathymetric lidar data collected as part of the National Coastal Mapping Program. Data acquisition occured between May and June 2010. The coverage area includes Florida, Georgia, South Carolina and North Carolina coasts from Cape Canaveral, FL to Cape Lookout, NC. Data coverage generally extends along the coastline from the waterline inland 500 meters.

This data was collected by a Leica ALS 50 Phase II Plus, Digital Aerial Camera System (DACS II) and CASI 1500 Hyperspectral sensor. The data was collected on a single remote sensing platform for use in coastal mapping and charting activities. Native lidar data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software processes the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis.The 3-D position data are used to generate a series of gridded file products, with each covering approximately 5 kilometers of shoreline.

In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

These data were collected as a part of the National Coastal Mapping Program to depict the elevations above water in the Florida, Georgia, South Carolina and North Carolina coastal zone.

The data are not attributed.

N/A

Based upon comparison with surveyed ground control points, the vertical accuracy tested better than +/- 0.15 m

Cloud Cover: Unknown

The project area was verified for complete coverage.

The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.15 meters, and different

flight line data agreed within 0.15 meters.

The USACE collected, processed, and provided the data to the NOAA Office for Coastal Management (OCM). OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https.
