2007 Florida Division of Emergency Management (FDEM) Lidar Project: Gulf County
Dataset Identification:
Resource Abstract:
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.
This data was collected for Gulf County, Florida during 9 - 22 July 2007 and covers approximately 650 square miles. This is
a classified lidar data set; unclassified data (class 1), bare-earth points (class 2), and water returns (class 9). The LiDAR
data was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. A footprint
of this data set may be viewed in Google Earth at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/534/supplemental/FDEM_Lidar_Gulf_County.kmz

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.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
measure Description
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.
Quantitative Result
result value 1

AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
The LiDAR is required to meet 0.60 feet Fundamental Vertical Accuracy (FVA) and 1.19 feet Consolidated Vertical Accuracy (CVA).
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy
measure Description
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 Gulf and western Franklin Counties, Florida
satisfies the criteria: Countywide lidar dataset tested 0.12 m (0.41 ft) vertical accuracy at 95% confidence level in open
terrain, based on open terrain RMSEz (0.21 ft) x 1.9600. Countywide lidar dataset tested 0.66 ft vertical accuracy at 95%
confidence level in all land cover categories combined, based on consolidated RMSEz (0.34 ft) x 1.9600. Please refer to the
Supplemental_Information field above for the link to the "Final Report of Specific Purpose LiDAR Survey - LiDAR, Breaklines,
and Contours for Gulf County, Florida" for a very detailed report about this data set.
