Georgia Coastal Counties Land Use and Urbanization in 5 Mile Buffer of Shellfish Harvest Areas
The Georgia Department of Natural Resources, Coastal Resources Division, Shellfish Sanitation Program (SSP) regularly monitors points along the Georgia coast and has designated safe harvesting areas for public recreation and commercial shellfish harvesting. Shellfish do grow in other areas than are designated as safe harvesting areas, but the entire coastal waters can not be monitored for harmful bacteria.

Digital Ortho Image Creation of Hall County Aerial Photos
The Hall County National Resource Conservation Service (NRCS) has several sets of historic aerial imagery. The purpose of this project was to digitize one of these sets of images such that the public can utilize them for perpetuity. The project outlines the methods used in digitizing, georeferencing, ortho-rectifying, and mosaicking a set of thirty-five images taken October 12, 1980. This project was made possible by support from the Institute for Environmental Spatial Analysis at Gainesville State College and from a grant provided by the Georgia View Consortium.

Probability Model for Prehistoric Archaeology Sites in the Chattahoochee-Oconee National Forests
The Chattahoochee-Oconee National Forests contain many known prehistoric and historic archaeological sites. This project was designed to use a computer model based on logistic regression to aid in the identification of areas with a high probability for finding additional prehistoric sites. By identifying the characteristics of locations of known prehistoric human activity it should be possible to predict the likelihood of finding evidence of prehistoric activity at other locations. Such a tool would help to focus efforts to locate previously unknown archaeological sites. The approach used by this project is based on binary logistic regression. Using data from a set of points including both known prehistoric archaeological sites and random points, a regression equation for the natural log of the probability of a point being a prehistoric site was developed. Raster calculation was then performed to produce a probability surface for the study area.

Preliminary Lake Lanier Bathymetry Study
This project, made possible by the generous support of Johnson Outdoors, chronicles the first in a series of experiments designed to test the extent and reliability of a new form of cost-effective bathymetry. Through the use of a modified Humminbird brand depth finder linked to a GPS unit, GSCSAL is able to map the dynamics of the Lake Lanier Reservoir; an important natural resource in North Georgia. Reservoirs experience physical change due to human development, sediment deposition, erosion, etc. Understanding the topologic and hydrologic characteristics of Lake Lanier and how those characteristics change over time is vital to the effective management of the reservoir.

GA Bay Complex Wildfire Imagery Project
This project initiated as the wildfire incident was drawing to a close in mid-June of 2007. As the suppression effort relaxed there was great interest in quantifying the amount of damage to timber resources and in getting restoration efforts underway. The SPOT 5 satellite was commissioned by the Georgia Forestry Commission (GFC) in mid-June to collect multi-spectral high resolution imagery of the burned area to assist in these efforts. Due to cloud conditions, a suitable image could not be obtained until mid-August of 2007. The imagery was nonetheless processed to provide additional information regarding vegetation conditions and areas of suppression related disturbance, which was provided to governmental agencies and other stakeholders in the area.

Madison County E911 Map Book
GSCSAL staff and students have compiled a map book for Madison County, Georgia's 911 services. The map sheets include roads in the area labeled with addressing ranges and county road numbers, hydrography, points of interest, and other identifiable features that will aid emergency service members in reaching their destinations as quickly as possible. Work on this project has been a widely beneficial experience for both the students and faculty of Gainesville State College.

Hurricane Frequency Study
This study draws upon hurricane data collected over fifty-four years. The positions of the storms were calculated for density and then interpolated into a raster with hillshade for improved visualization. The aim of this project is to detect a trend in hurricane landfall through historical probability.

Georgia Landsat Coverage
Produced initially for use in the Gainesville State College Remote Sensing course, this map product is currently on its way to remote sensing analysts throughout Georgia via the Georgia View program. This product serves as a quick visual reference for analysts trying to discern which Landsat path and row scene will cover their area of interest, as well as a brief descriptor of the Landsat program, the characteristics of its sensors, and a timeline of data available.

Lake Lanier Association
GSCSAL is currently involved in a project to map the data collected by the Lake Lanier Association and its volunteers. Once a month volunteers go to designated collection sites throughout the lake and take secchi readings (overall assessment of how far down an object is visible from the surface, thus water clarity), chlorophyll readings, and many other environmental readings that could prove useful in an analysis. The volunteers have been collecting data on one of Georgia's most beautiful lakes for years, now GIS is helping them to visualize the true nature of this data in hopes that it will prove beneficial in keeping the lake clean and safe for years to come.

Georgia's Presidential Election History
Voting results in Georgia have a history of being quite variable in years past. Using a Geographic Information System, student Mark Mathis has compiled voting data from several years and linked that data to its geographic counterpart to better visualize how different regions of the state have cast their ballot.

Hall County Fire Service Areas
GSCSAL is currently involved in a project to map the Fire Service Areas for the Hall County Fire Department. For purposes of ensuring public safety, each station is required to have a detailed account of all areas within a 1.5, 2.5, and 5 mile driving distance from their location. Using a detailed road network provided by the GIS dept. of Hall County Planning, GSCSAL staff were not only able to delineate these coverage areas, but also to compute the total amount of road covered by each driving distance. This can then be related to the total amount of road in the county to get an idea of areas that might need improvement.

Gainesville State College Campus Map
When the time came around to develop a new map for the Gainesville State College campus, GSCSAL members used the opportunity to put their ArcScene skills to the test. ArcScene allows GIS users to create 3-Dimensional environments from geographic data, thus creating a virtual world that is an accurate model of the real thing.

R Ranch Horse Trails
Students from both the Introduction to GIS and the Cartography classes worked together on this project to provide the R Ranch Resort with an accurate map of their horse trails. Students collected data on the trails using a Global Positioning System (GPS) receiver. The data was then taken back to the school and post-processed for greater accuracy. The trails were then combined with other geographic data, such as roads and hydrographic features, to provide a large wall map for the visitor's center and a smaller version for riders to carry on their person.

Smithgall Arboretum
With land recently donated to the Atlanta Botanical Garden in 2000 by Charles and Lessie Smithgall, new development is scheduled to take place that will transform the property into a wonderful site for research, conservation, and education. GSCSAL is currently working with the Smithgall Arboretum on a number of projects that will seek to map and model this resource in hopes of better understanding its many wonders. This study begins with the definition of the watershed, the area that contributes rainfall and runoff to the Arboretum.

Gainesville State College Fitness Trails
Trail data was collected by student Mike Martin using a Global Positioning System (GPS) unit. The data was then post processed for greater accuracy and compiled into a geodatabase for organization. This project benefits the students of Gainesville State College who want to use the trails, but may not be familiar with the network or how long various routes are.
