2007 Northwest Water Manangement District Lidar: Gadsden County, Florida
This kmz file shows the extent of coverage for the 2007 NWFWMD Gadsden County, FL lidar data set.
LIDAR-derived binary (.las) files containing points classified as bare-earth and canopy (first return) were produced for the 2007 Northwest Florida Water Management District - Gadsden County, Florida lidar mapping project. The files were provided in a scheme of FDEM-derived 5,000 x 5,000 foot (1500 x 1500 meter) tiles. Horizontal mapping units are in UTM meters, vertical mapping units are in U.S. survey feet. The total mapping area covers 535 square miles of Gadsden County, Florida.

Lidar points are attributed with the following classifications: 1 - canopy 2 - ground (bare earth) 9 - water Lidar intensity values range from 0-255. Lidar return values range from 1-3. Flight line numbers range from 1-19. All deliverables meet specifications in contract. LAS Files meet ASPRS Classification Standards.
|Purpose:||The purpose of the project is to produce accurate, high-resolution data for planning, analysis, and for use with other data sets. Merrick & Company obtained LiDAR data over approximately 535 square miles covering the majority of Gadsden County, Florida. The LiDAR data has been processed to result in a data set that is suitable for the future generation of 2-foot contours. These data will be used to support FEMA's Map Modernization Program through the creation of high-resolution digital elevation models (DEMs). These DEMs support a variety of applications, including improved floodplain delineation, hydrologic and hydraulic modeling, hazard mapping as well as other planning activities.|
