LIDAR-derived binary (.las) files containing points classified as bare-earth and canopy (first return) were produced for the 2007/2008 Northwest
Florida Water Management District - 5 Counties (Calhoun, Washington, Jackson, Liberty, Holmes), Florida lidar mapping project. ESRI GRIDs of
bare earth points are also provided. The files were provided in a scheme of FDEM-derived 5,000 x 5,000 foot (1500 x 1500 meter) tiles. Horizontal
mapping units are in UTM meters, vertical mapping units are in U.S. survey feet. The total mapping area covers approximately 2102 square miles.

The purpose of the project is to produce accurate, high-resolution data for planning, analysis, and for use with other datasets. Merrick obtained
LiDAR data over approximately 2,102 square miles covering all or portions of 5-Counties in Florida. The LiDAR data has been processed to result in
a data set that is suitable for the future generation of 2-foot contours.
These data will be used to support FEMA's Map Modernization Program through the creation of high-resolution digital elevation models (DEMs). These
DEMs support a variety of applications, including improved floodplain delineation, hydrologic and hydraulic modeling, hazard mapping as well as
other planning activities.

Accuracy
Verification of attribute accuracy of LIDAR data involves the use of filtering techniques. Auto-filtering uses algorithms to reclassify data in the
point cloud. Hand-filtering involves the use of a technician working in a graphic environment to reclassify the erroneous points that may remain in
the LIDAR point cloud after auto filter.
Horizontal Positional Accuracy
Horizontal accuracy is verified in three tests. During boresighting, adjoining flightlines are view in profile and hard edged features are
observed and if necessary the flightlines are adjusted for good relative horizontal and vertical fit. The second test for horizontal accuracy is
by comparing raw contours from each flightline against adjoining flightlines at specific points. The final test is the vertical LIDAR control
report.
Vertical Positional Accuracy
Survey control points were used to validate the accuracy of the LIDAR surface model after automatic and hand filtering. This surface exceeds the
NSSDA consolidated vertical accuracy specifications of 36.3 cm (1.19 ft) at the 95% confidence level.
; Quantitative Value: 0.15 meters, Test that produced the value:
RMSEz (m) based upon comparison of 176 survey checkpoint z-values with those of a bare-earth generated surface model at same geographic location.
Completeness Report
This dataset contains classified returns of the LIDAR sensor. The sensor data was verified in MARS software to ensure complete coverage.
Conceptual Consistency
Calibrations of the LIDAR flightline data are performed; this process is known as boresighting. The flightlines are compared to evaluate both their
relative and absolute accuracies.
LIDAR data was collected using Merrick's ALS50 Phase 2 sensor. The raw data was verified in MARS software for complete coverage of the project
area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then
processed through automated filtering that separates the data into different classification groups: error points, ground points,
and canopy/building points. The data was next taken into a graphic environment to reclassify the erroneous points that may remain in the LIDAR
point cloud after auto filter.

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 for data storage purposes and Digital Coast provisioning:
1. The data were converted from projected UTM (NAD83, Zone 16) coordinates to geographic (NAD83) coordinates
2. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03
3. The LAS header fields were sorted by latitude and updated
