LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform.
Using a combination of laser range finding, GPS positioning and inertial measurement technologies; LIDAR instruments are
able to make highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures and vegetation.
Using a LH Systems ALS50 Light Detection And Ranging (LiDAR) system, 262 flight lines of high density (submeter ground
sample distance) data were collected over areas in Bay, Calhoun, Jackson and Washington Counties in Florida. This data set
was collected at the same time as the collection for Jefferson County, FL. Collectively, these data sets cover
approximately 1201 square miles. The data acquisition occurred in 17 missions between February 22, 2007 and March
13, 2007. Multiple returns were recorded for each laser pulse along with an intensity value for each return.
This data was collected at sub-meter resolution to provide average point spacing of 0.7 m for collected points. Up to
5 returns were recorded for each pulse in addition to an intensity value.

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
The data was collected to support regulatory, land management and acquisition, planning, engineering, and habitat
restoration projects. It will also support the creation of Federal Emergency Management Agency Flood Insurance Rate Maps
(FEMA FIRM) and an integrated ground surface model for portions of these counties.

Reflective surface data represents the DEM created by laser energy reflected from the first surface
encountered by the laser pulse. Some energy may continue beyond this initial surface to be reflected by a subsequent surface
as represented by the Last Return data. Intensity information is captured from the Reflective Surface pulse and indicates the
relative energy returned to the sensor as compared to the energy transmitted. The Intensity image is not calibrated or
normalized but indicates differences in energy absorption due to the interaction of the surface materials with laser energy
at the wavelength transmitted by the sensor. Points are classified as on ground surface or not on ground surface to support
creation of a bare earth model from the data. Points in the filtered ground class determined to be in open waterways or water
bodies were reclassified as Water.

Completeness Measure
Cloud Cover: Unknown
Completeness Report
LIDAR is self-illuminating and has minimal cloud penetration capability. Water vapor in steam plumes
or particulates in smoke may cause reflection of LIDAR signals and loss of elevation information beneath these plumes.
Glass structures and roofs may appear transparent to the LIDAR signal and therefore may not register on the reflective surface.
Some asphalt formulations have been shown to absorb topographic LIDAR wavelength energy resulting in "pitting" of roof
surfaces using this material.

Data Collection:
Using a LH Systems ALS50 Light Detection And Ranging (LiDAR) system, 262 flight lines of high density (submeter ground
sample distance) data were collected over areas in Bay, Calhoun, Jackson and Washington Counties in
Florida. This data set was collected at the same time as the collection for Jefferson County, FL. Collectively, these data
sets cover approximately 1201 square miles. The data acquisition occurred in 17 missions between February 22, 2007 and
March 13, 2007. Multiple returns were recorded for each laser pulse along with an intensity value for each return.
During the LIDAR campaign, the Sanborn field crew conducted a GPS field survey to establish final coordinates of the ground
base stations for final processing of the base-remote GPS solutions. Four (4) airborne global positioning system (GPS) base
stations were used to support the LiDAR data acquisition. GPS ground control check points were also collected by the LiDAR
team while onsite for product accuracy validation and delivery.

Airborne GPS Processing:
Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best
estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface
for each flight line. The overlap between flight lines was removed to provide a homogeneous coverage, and the coverage was
classified to extract a bare earth digital elevation model (DEM). Airborne GPS is differentially processed using the
GrafNAV V7.50 software by Waypoint Consulting of Calgary, Alberta, Canada. The PDOP and distance separation is as follows:
IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada. The
reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of Atlanta,
Georgia. The classification and quality control (QC) of LiDAR data is carried out using TerraScan software by Terrasolid
Limited of Helsinki, Finland.

IMU data Processing:
IMU data provides information concerning roll, pitch and yaw of collection platform during collection event. IMU
information allows the pulse vector to be properly placed in 3D space allowing the distance from the aircraft reference
point to be properly positioned on the elevation model surface. IMU data is processed using the PosPac V4.2 software by
Applanix Corporation of Richmond Hill, Ontario, Canada.

LIDAR Ground Point Classification:
The classification and quality control (QC) of LiDAR Ground point class is carried out using TerraScan software by
Terrasolid Limited of Helsinki, Finland. In the filtering process points are classified as Ground or one of several
non-Ground classes including Unclassified, Overlap, and Low Points.
2007-10-01T00:00:00
Reclassification of Water Points:
LiDAR returns from open water surfaces are commonly included in the Ground class by the ground filtering algorithms.
Using 2D and 3D visualization methods, 2D vector polygons were digitized for significant waterways and water bodies that
were readily identifiable in the LiDAR data. These polygons were then used to re-classify points in open water from the
filtered Ground class to the Water class.

The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity
and elevation measurements. OCM performed the following processing on the data to make it available within the LiDAR Data
Retrieval Tool (LDART):
1. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03.
2. The LAS header fields were sorted by latitude and updated.
3. The data was filtered to eliminate outliers.

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.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
