This Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted for a coalition of GIS practitioners,
including the Florida Division of Emergency Management (FDEM), Florida Water Management Districts, Florida Fish and Wildlife
Conservation Commission, Florida Department of Environmental Protection, Army Corps of Engineers Jacksonville District, and
other state and federal agencies. The goal for this project is to use the LiDAR data as new elevation inputs for updated SLOSH
data grids. The ultimate result is the update of the Regional Hurricane Evacuation Studies (RHES) for the state. The State of Florida
Division of Emergency Management LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor.
Data were collected for 707 square miles in Franklin County, Florida from May 4 - August 16 2007. This is a classified lidar data set.
The data are classified: 1 = Unclassified, 2 = Ground (Bare Earth), 7 = Noise and 9 = Water. The FDEM Baseline Specifications
required a maximum post spacing of 4 feet, however, the PDS (Program and Data Solutions) team required a much higher point density of its
subcontractors in order to increase the probability of penetrating dense foliage during the mandated summer acquisition; with nominal
post spacing of 0.7 meters per flight line and 50% sidelap between flight lines, the average point density is 4 points per square meter.

Purpose: |
The LiDAR topographic mapping survey is to support the Florida Division of Emergency Management (FDEM) development and maintenance of Regional Hurricane Evacuations Studies (RHES), which include vulnerability assessments, and to assist disaster response personnel in understanding the threats to Florida's citizens and visitors. Additional intended uses for this survey are growth management, map modernization/floodplain mapping, natural lands stewardship, and homeland security planning. |

Data Quality
Horizontal Positional Accuracy: |
Lidar source compiled to meet 1m horizontal accuracy.; Quantitative Value: 1 meters, Test that produced the value: The PDS team does not perform independent horizontal accuracy testing on the LiDAR. LiDAR vendors perform calibrations on the LiDAR sensor and compare data to adjoining flight lines to ensure LiDAR meets the 1 meter horizontal accuracy standard at the 95% confidence level. |
---|---|
Vertical Positional Accuracy: |
The LiDAR is required to meet 0.183 m (0.60 ft) Fundamental Vertical Accuracy (FVA) and 0.363 m (1.19 ft) Consolidated Vertical Accuracy (CVA). ; Quantitative Value: 0.162 meters, Test that produced the value: Based on the vertical accuracy testing conducted by PDS, using NSSDA and FEMA guidelines, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600. The dataset for Franklin County, Florida satisfies the criteria: Countywide lidar dataset tested 0.162 m (0.53 ft) vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz 0.082 m (0.27 ft) x 1.9600. Countywide lidar dataset tested 0.225 m (0.74 ft) vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz 0.116 m (0.38 ft) x 1.9600. |

Process Steps
Process Step 1
Description: |
The ABGPS, IMU, and raw Optech 3100ea LiDAR data are integrated with Optech Incorporated's DASHMap, version 1.1 software, Terrascan software and Microstation software. The resultant file is in a LAS binary file format. The LAS file version 1.1 format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return #, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and GRS80 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian calendar. |

Process Date/Time: | 2008-01-01 00:00:00 |
Process Step 2
Description: |
The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters are applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. The header file for each dataset is complete as define by the LAS 1.1 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The LAS files do not include overlap. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground (Bare Earth) Class 7 = Noise Class 9 = Water |

Process Step 3
Description: |
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 Digital Coast: 1. The data were converted from State Plane Florida North coordinates to geographic 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. |
