Elevation measurements were collected over the area using the NASA Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the earth's surface through an 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 plane travels over the target area at approximately 50 meters per second at an elevation of approximately 300 meters. The EAARL, developed by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 15 centimeters. A sampling rate of 3 kHz or higher results in an extremely dense spatial elevation data set. Over 100 kilometers of coastline can be easily surveyed within a 3 to 4 hour mission time period. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

Converting dense Lidar elevation data into a readily usable format without loss of essential information requires specialized processing. The U. S. Geological Survey's Coastal and Marine Geology (CMG) Program has developed custom software to convert raw lidar data into a GIS compatible map product to be provided to GIS specialists, managers, and scientists. The primary tool used in the conversion process is Advanced Lidar Processing System (ALPS), a multi-tiered processing system developed by a USGS/NASA collaborative project. Specialized processing algorithms are used to convert raw waveform Lidar data acquired by the EAARL to georeferenced spot (x,y,z) returns for "first surface" and "bare earth" topography. These data are then converted to the North American Datum of 1983 and the North American Vertical Datum of 1988 (using the Geoid 03 model). The files are in the Quarter Quad tiling format and the exact tile location is contained in the filename at n88_########_mf_be where ####### is the Quarter Quad tile ID. The development of custom software for creating these data products has been supported by the USGS CMG Program's 'Decision Support for Coastal Parks, Sanctuaries, and Preserves' project. Processed data products are used by the USGS CMG Program's 'National Assessments of Coastal Change Hazards Project' to quantify the vulnerability of shorelines to coastal change hazards such as severe storms, sea-level rise, and shoreline erosion and retreat.

The NASA Experimental Advanced Airborne Research Lidar (EAARL) laser scanner collects the data using a green (532nm) raster scanning laser, while a digital camera acquires a visual record of the flight. The data are stored on hard drives and archived at the U. S. Geological Survey, FISC St. Petersburg office and the NASA office at Wallops Flight Facility. The navigational data are processed at Wallops Flight Facility. The navigational and raw data are then downloaded into the Advanced Lidar Processing System (ALPS). Data are converted from units of time to x,y,z points for elevation.

The files contained Lidar elevation and intensity measurements. The data were projected in UTM coordinates (NAD83; Zone 16N) and referenced to the North American Vertical Datum of 1988 (NAVD88) using the Geoid03 model. The following processes were performed to make the data available within the Digital Coast: 1. The data were converted from UTM (NAD83; Zone 17N) to geographic coordinates (NAD83). 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoidal) heights using the Geoid03 model. 3. The data were reclassified to reflect the ASPRS LAS classifications (1 - unclassified, 2 - bare earth). 4. The LAS data were sorted by latitude and the headers were updated. dateTime: DateTime: 2012-01-25T00:00:00 source: (LI_Source) description: Source Contribution: none | Source Geospatial Form: LAS | Type of Source Media: Point elevation measurements collected by the EAARL sensor. sourceCitation: (CI_Citation) title: EAARL Coastal Topography- Northern Gulf of Mexico, Post-Hurricane Ivan date: (CI_Date) date: 2008-01-01 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2004-09-19 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
