Colquitt County Landcover Maps:
1984, 2006
Colquitt County,
GA has been doing long term planning without detailed knowledge and relative
abundance of the landcover types. There is general anecdotal knowledge of
the landcover change over time, but there is no quantitative inventory of
change. This project has produced landcover maps for 1984 and 2006 utilizing
Landsat multispectral imagery and remote sensing techniques. A quantitative
landcover change analysis was performed and the results produced in a map
form. These maps are to allow land planners to have to have historical and
relatively recent quantitative maps form which to plan

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.

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.

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, GCSAL 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.

Madison County E911 Map Book - GCSAL staff and students are
currently compiling 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. Created by: Mike Martin, Jill Graham, Cathy Dull,
and Matt Miller (Instructor of GIS) |

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 DEM-like raster with hillshade for improved visualization. The
aim of this project is to detect a trend in hurricane landfall through
historical probability.

Zoning Map of the City of
Jefferson, GA - Produced during the Special topics
course, this map depicts the parcels for the city of Jefferson, GA according
to their particular zoning designation. Maps like this assist all
levels of government, especially local government. The ability to
visualize, quantify, and locate parcels that fit a certain criteria quickly
and efficiently is part of what makes using GIS for management so powerful.
This map is not an official document.

Fortune 500 Companies -
This project reveals several interesting characteristics of the Fortune 500
companies in the year 2004. It shows their geographic relation to one
another, as well as their placement throughout the United States.

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.

Sapelo Island Erosion - Like all of
Georgia's barrier islands, erosion and deposition on Sapelo island are facts
of life. Currents erode the island at its northern end and then
deposits the sediment in the southern end. This "rolling" transition
gradually changes the islands position over time. Cathy Dull,
Coordinator of GIS Services at GCSAL, is currently using remotely sensed
imagery to monitor this changing condition. By classifying
multispectral imagery into land cover categories, Cathy is able to
successfully put a number on the actual rate of change as well as the
location. Created by:

Lake Lanier Association - GCSAL 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.
