| 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, 17 Contractor: Sanborn
