2006 Florida LiDAR: Escambia, Santa Rosa, and Walton Counties
|
ESCAMBIA: The Light Detection and Ranging (LiDAR) LAS dataset is a survey
of select areas within Escambia County, Florida. These data were produced for Dewberry
and Davis LLC. The Escambia County LiDAR Survey project area consists of approximately
803 square miles. The LiDAR point cloud was flown at a density sufficient to support
a maximum final post spacing of 6 feet for unobscured areas. Land Air mapping acquired
110 flightlines between June 21, 2006 and July 18, 2006. The data was divided into
5000' by 5000' foot cells that serve as the tiling scheme. The Escambia County LiDAR
Survey was collected under the guidance of a Professional Mapper/Surveyor. Dates of
Collection: 20060621-20060718 Contractor: Dewberry and Davis, LLC SANTA ROSA: LiDAR
data collection was performed utilizing a Leica ALS-50 sensor, collecting multiple
return x, y, and z data as well as intensity data. LiDAR data was processed to achieve
a bare ground surface. LiDAR data was delivered in LAS format. Dates of Collection:
20060112-20060228 Contractor: Photo Science, Inc. WALTON: LIDAR data is remotely sensed
high-resolution elevation data collected by an airborne collection platform. Using
a combination of laser range finding, GPS positioning and inertial measurement technologies;
LIDAR instruments are able to make highly detailed Digital Elevation Models (DEMs)
of the earth's terrain, man-made structures and vegetation. This data of Walton County,
Florida, was collected at sub-meter resolution to provide average point spacing of
0.7m for collected points. Up to 5 returns were recorded for each pulse in addition
to an intensity value. No data for Eglin AFB, permission to fly over was ever granted.
Dates of Collection: 20060710-11, 19-20, 22-23, 26-29, 20060801, 03, 06-07, 13, 15,

Lidar Use Limitation |
These data depict the elevations at the time of the survey and are only
accurate for that time. Users should be aware that temporal changes may
have occurred since this data set was collected and some parts of this data may no
longer represent actual surface conditions. Users should not use this data
for critical applications without a full awareness of its limitations. Any conclusions
drawn from analysis of this information are not the responsibility of NOAA
or any of its partners. These data are NOT to be used for navigational purposes.

The NOAA Coastal Services Center (CSC) received files in LAS format.
The files contained LiDAR intensity and elevation measurements. CSC performed the
following processing on the data to make it available within the LiDAR Data Retrieval
Tool (LDART): 1. The LAS files were converted from UTM coordinates to geographic coordinates.
2. The LAS header fields were sorted by latitude and updated. 3. The data was filtered
to eliminate outliers.

The NOAA National Geophysical Data Center (NGDC) received lidar data
files via ftp transfer from the NOAA Coastal Services Center. The data are currently
being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/.
The data can be used to re-populate the system. The data are archived in LAS or LAZ
format. The LAS format is an industry standard for LiDAR
data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS);
LAZ is a loseless compressed version of LAS developed by
Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates
(either NAD83 or ITRF94). The data are referenced vertically to
the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most
up to date geoid model when transforming to orthometric heights.
