This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 8.9831528411952133e-009. Longitudes are given to the nearest 8.9831528411952133e-009. Latitude and longitude values are specified in Decimal Degrees.
The horizontal datum used is D WGS 1984.
The ellipsoid used is WGS 1984.
The semi-major axis of the ellipsoid used is 6378137.0.
The flattening of the ellipsoid used is 1/298.257223563.

Data sources produced in this process:
Horizontal accuracy has not been estimated and is dependent on the positional accuracy of the lidar data, which is estimated to be within 1 meter.
Vertical accuracy has not been estimated and is dependent on the positional accuracy of the lidar data. Estimated accuracy of lidar surveys are +/- 15 centimeters. However, vertical accuracies may vary based on the type of terrain (for example, inaccuracies may increase as slope increases or with the presence of extremely dense vegetation) and the accuracy of the GPS and aircraft-attitude measurements.
These data include dune morphology data used to generate predictions of hurricane-induced erosion. Elevation data from lidar surveys are not included. Predicted hurricane wave and water level predictions are not included, but can be obtained from the online report.
No additional checks for consistency were performed on this data.
