Laser mapping uses a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation and topography. The laser emits laser beams at high frequency and is directed downward at the earth's surface through a port opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The aircraft travels over the beach at approximately 60 meters per second while surveying from the low water line to the landward base of the sand dunes.

The instrument, originally designed for mapping ice sheets in Greenland, is called the Airborne Topographic Mapper or ATM. The ATM II (the latest version), operates with a Spectra Physics laser transmitter, which provides a 7 nanoseconds long, 250 microjoules pulse at a frequency-doubled wavelength of 523 nanometers in the blue-green spectral region. The laser transmitter can function at pulse rates from 2 to 10 kilohertz (kHz). The laser system with a separate cooling unit weighs approximately 45 kilograms (kg) and requires approximately 15 amperes of power at 115 volts. The transmitted laser pulse is reflected to the surface of the earth with the aid of a small folding mirror mounted on the back of a secondary mirror of a rotating scan mirror assembly mounted directly in front of the telescope. The scan mirror, which is rotated at 20 hertz, is comprised of a section of round aluminum stock, machined to a specific off-nadir angle. A scan mirror with the off-nadir angle of 15 degrees was utilized, producing an elliptical scan pattern with a swath width equal to 50 percent of the approximately 700-meter aircraft altitude. The reflected laser pulse is transmitted to a photo-multiplier assembly that consists of a lens, a narrow bandpass filter, and a single photomultiplier tube. Note: The Spatial Reference section of this document may lack fully FGDC-compliant information regarding projection parameters (i.e., Central meridian, false Northing, etc.). The State Plane or UTM Zone will be supplied, and the corresponding parameters can be found in Appendix C of: Snyder, John, 1987, Map Projections, a Working Manual (U.S. Geological Survey Professional Paper 1395): Washington, U.S. Government Printing Office.

Data quality info: Data quality: Scope: Scope: Hierarchy level: Scope code: dataset Report: Quantitative attribute accuracy: Name of measure: Accuracy Evaluation method description: Raw elevation measurements have been determined to be vertically accurate to within 15 cm. Processing steps (datum conversion, projection, grid interpolation, etc.) introduce additional error factors which have not been tested at the time of this publication. Result: missing Report: Absolute external positional accuracy: Name of measure: Horizontal Positional Accuracy Evaluation method description: The ATM LIDAR elevation points are known to be horizontally accurate to +/- 0.8 meters at an aircraft altitude of 700 meters. Result: missing Report: Absolute external positional accuracy: Name of measure: Vertical Positional Accuracy Evaluation method description: The ATM LIDAR elevation measurements have been found to be within +/- 15 centimeters of each other in successive and overlapping passes of the same area. In comparisons of LIDAR data for a small geographic region with various ground surveys the differences are between +/- 15 to 20 centimeters. The accuracy of the majority of the data is estimated to be consistent with the above stated results. At this time, there has been no large scale verification of the data. Result: missing Report: Completeness commission: Name of measure: Completeness Report Evaluation method description: All elevation data points that appeared to be within a reasonable vertical range were retained, and other points were thrown away. This filtering process was performed 'by eye'. Result: missing Report: Conceptual consistency: Name of measure: Conceptual Consistency Evaluation method description: Not applicable Result: missing Lineage: Lineage: Statement: missing Process step: Process step: Description: The vertical values in this data set have been filtered through visual inspection to find abnormally high and abnormally low values. In addition, this data was processed using a spatial filtering program that identifies and discards outlier elevation measurements. This program reads each elevation measurement within a file and identifies "spatially close" points (i.e. those neighboring points within a fixed radius of the point). The mean and standard deviation is calculated using the elevations of these points. If the elevation difference from the mean of the point under consideration is more than 2 standard deviations and greater than a defined distance the point is discarded.
