Blandy Road Jason Ray May 5, 2005
Problem Statement -GCSU has about three-hundred and seventy acres of land off of Blandy Road. The property has been clear cut in the past five years for finances pertaining to the construction of GC&SUs new intramural fields. The property owned by GCSU is uninhabited and has one standing infrastructure in an antenna station. The property is in close proximity to West Complex and would be an astounding area for recreational purposes. The problem is that GCSU does not know what they want to do with this land, because they do not know what they have.
Field Methods Information on trails, clearings, and creeks was collected by walking the entire length of the trails, and using a GPS unit, points were plotted every few meters and along curves. The creek was captured in the same fashion as well. For the clearings the perimeter was plotted using only five to six points.
GIS Usage A portable GPS unit was used to collect data for the property, including trails, clearings and the creek. The points were found using the NAD 1983 datum under UTM Zone 17N. The trails and creek points were then converted into lines with the use of a point to line extension. The clearings were converted using a point to polygon extension.
GIS Usage The Doq99_browns_crossing_ne.img to construct land cover polygons. The Drg_browns_crossing.img to construct a representation of the contours found throughout the property. The contour lines were then reconstructed into a raster image for the purpose of portraying a three-dimensional representation of the property.
Within the property boundary, the portable GPS unit was used to collect both trails, three clearings along the trail and the creek that intersects the trail in the west. Blandy Road HWY 49 Milledgeville ->
Trail Leading to Creek Crossing
The vast majority of land cover within the property boundary is Pine, but along the trails you can notice where the Pine trees have been devastated by loggers. (shown in white).

History Prior to 1968, the land off of Blandy Road was owned by the State of Georgia. It wouldnt be until August 23, 1968 that the land was bought from the government of Georgia. The land was purchased by the Baldwin County Board of Education on this date. The land was then conveyed to Georgia College & St. Univ. on September 8, 1971 after being surveyed by Calvin W. Rice, a Registered Georgia Land Surveyor Number 58. The property has never been deeded residential, only government. References: Baldwin County Courthouse Tax Assessors Office and Deeds Office
Three-Dimensional Imagery To construct the 3-d images of the property I first traced the contour lines on the DRG map and saved it as a shapefile. Next, I converted the shapefile, in ERDAS IMAGINE, to an ARC coverage file. In Virtual GIS, the ARC coverage file of the contours could then display a DEM.img which projected the landscape in three-dimension. The landscape shapefile was also converted into an ARC coverage file and then projected on top of the DEM.img. The procedure was also used to portray the trails, creeks, roads, antenna station, and property boundary line into the 3-D image.
Contours for the property range from 290 ft. to 490 ft. ranging from yellow to red accordingly.

Results Within the property boundary there are seven differing landscapes. The total area of the Blandy property is acres. Landscape Area and Percent of Total Area: Pine: acres or 62.1% Pine Cut: acres or 33.9 % School: 5.35 acres or 1.6% Pasture: 5.26 acres or 1.6% Hardwood: 1.95 acres or 0.2% Urban: 1 acre or 0.15% Recreational fields: 0.5 acre or 0.08%

Summary The purpose of this project was to show what GC&SU had purchased and what they had to develop in regards to new recreational facilities.
