Description:
Abstract:
The Georgia Mountains Regional Development Commission wished to establish a digital surface model of Banks, Forsyth, Franklin, and Stephens Counties.
Purpose:
The purpose of the project was to acquire LiDAR (Light Detection And Ranging) data to establish a surface Digital Elevation Model (DEM) of Banks, Forsyth, Franklin, and Stephens Counties.  A 5-foot contour surface will be developed for areas within the National Forest boundary - equating to a 1"=200' mapping scale dataset.  And, a 2-foot contour surface will be developed for areas outside the National Forest but within the project boundary

Process_Description:
Ayres Associates utilized mathematical algorithms through TerraSolid applications to filter high points (noise), low points (noise), low vegetation points (points 0.1 - 1 foot above bare earth points) , medium vegetation points (points 1.1 - 10 feet above bare earth points), high vegetation points (points 10.1+ feet above bare earth points), and water points from entire point cloud of the county of Forsyth of the Georgia Mountains Regional Development Center.
Process_Step:
Process_Description:
Ayres Associates prepared FGDC compliant metadata for each deliverable product.
