* » Abstract

This data set is one component of a digital terrain model (DTM) for the Florida Division of Emergency Management's (FDEM) Project Management and Technical Services for Mapping within Coastal Florida (Contract 07-HS-34-14-00-22-469), encompassing the entire coastline of Florida.

This survey was performed according to Baseline Specifications v 1.2. These specifications were developed by a coalition of GIS practitioners, including the Florida Division of Emergency Management, Florida Water Management Districts, Florida Fish and Wildlife Conservation Commission, Florida Department of Environmental Protection, Army Corp of Engineers Jacksonville District, and other state and federal agencies as the model requirements for orthophotography and LiDAR data collection for publicly funded projects within Florida.
* 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.

This LiDAR data represents the complete set of data for all the project areas in southwest Florida.
Conceptual Consistency

The LiDAR DTM was developed in accordance with the Baseline Specifications 1.2. The DTM is intended to support 2-foot contours, and

the vertical accuracy of ground points in unobscured areas is not to exceed 0.6-feet RMSE.

Process Steps

Process Step Number 1
» Description

LiDAR was collected within a very small

coastal area of Pasco County.

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.

» 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.

In 2014 OCM performed the following:

1. Isolated Pasco county data

2. Updated project footprint and KMZ
