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.

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 which is 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.

Smithgall
Arboretum Watershed
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. GCSAL 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. Because the
Arboretum only takes up 1/3 of the watershed, it becomes important to be
aware of the other 2/3.
