Title: 2007 Florida Division of Emergency Management (FDEM) Lidar Project: Southwest Florida
Short Name: fdem2007_southwest_m529_metadata
Status: Completed
Publication Date: 2014-12-09
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 is a classified lidar data set, bare-earth points (class 2), noise points (class 7), water returns (class 9), and unclassified data (class 1). Class 12 contains LiDAR points removed from the overlap region between adjacent flight lines. The LiDAR data was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas.

This data set is a collection of smaller project areas collected at different times in southwest Florida. Specifically, the data were collected within portions of Pinellas, Hillsborough, Manatee, Sarasota, Charlotte, Lee, Collier, and Monroe. In the original project 2 sections of Pasco county were used: data collection in 2004 as well as a small coastal section in 2008. These have been removed and designated as individual projects named 2004 Pasco - Classified and 2008 Coastal Pasco respectively.

The dates of collection are:

Project Area B: 20070706-20070810

Project Area C: 20070706-20070810

Project Area D: 20070717-20070729

Project Area E: 20070717-20070708

Project Area F: 20070618-20070806

Project Area G: 20070612-20070630, 20070702, 20070714, 20070804-20070805

Project Area H: 20070615-20070629

Sarasota Buy Up: 20070828-20070830

DEMs are available by request. Please submit an email to coastal.info@noaa.gov with the appropriate subject line.

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.

Process Steps

Process Step 1

CC ID: 1138643
Description:

LiDAR was collected within portions of Pinellas, Hillsborough, Manatee, Sarasota, Charlotte, Lee, Collier, Monroe, and a very small

coastal area of Pasco, Counties.

System Parameters/Flight Plan.

The LiDAR system acquisition parameters were developed based on a maximum average ground sample distance of 4 feet. Two Leica

ALS50 sensors were used for acquisition. Acquisition specifications for the two sensors were as follows:

Sensor 19

Field of View (full angle) - 29 degrees

Nominal flight altitude (AMSL) - 3999.30 feet

Airspeed - 54.02 meters/sec

Laser pulse rate - 75,000 Hz

Nominal swath width (on ground) - 2068.58 feet

Maximum cross track point spacing - 3.91 feet

Maximum along track point spacing - 3.94 feet

Average point spacing - 2.21 feet

Flight line spacing - 1544.95 feet

Side overlap - 25.31 percent

Sensor 59

Field of View (full angle) - 29 degrees

Nominal flight altitude (AMSL) - 3999.30 feet

Airspeed - 60.70 meters/sec

Laser pulse rate - 84,400 Hz

Nominal swath width (on ground) - 2068.58 feet

Maximum cross track point spacing - 3.94 feet

Maximum along track point spacing - 3.91 feet

Average point spacing - 2.21 feet

Flight line spacing - 1413.72 feet

Side overlap - 31.66 percent

LiDAR System Calibration.

Prior to the LiDAR acquisition, the system underwent a calibration to verify the operational accuracy and misalignment angles.

Boresight calibrations were performed for each LiDAR system at the beginning and end of each flight mission.

LiDAR Data Acquisition.

LiDAR data acquisition only occurred when the sky was sufficiently clear of clouds, smoke, and atmospheric haze. The LiDAR data

was processed immediately after the acquisition to verify the coverage had no voids.

GPS/Inertial Measurement Unit (IMU) Post Processing.

The GPS and IMU data was post processed using differential and kalman filter algorithms to derive a best estimate of trajectory.

The quality of the solution was verified to be consistent with the accuracy requirements of the project.

LiDAR Processing and Classification.

The LiDAR data was post processed and verified to be consistent with the project requirements in terms of post spacing and absence

of artifacts. The point cloud underwent classification to determine bare-earth points (class 2), noise points (class 7),

water returns (class 9), and unclassified data (class 1). Class 12 contains LiDAR points removed from the overlap region between

adjacent flight lines. The MASSPOINT feature class contains ground (class 2) points only.

Process Step 2

CC ID: 1138644
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 West 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.

4. revisited

5. In the original project 2 sections of Pasco county were used: data collection in 2004 as well as a small coastal section in 2008. These have been removed and designated as individual projects named 2004 Pasco - Classified and 2008 Coastal Pasco respectively.
