A study of the changes that have occurred over the last 22 years in coastal Georgia and South Carolina is being performed by the University of South Carolina and the Georgia Institute of Technology under NASA funding. This paper reports on the part of the study focused on the Savannah area of coastal Georgia. Eleven dates of Landsat multispectral scanner (MSS) and landsat thematic mapper (TM) multispectral image data were georeferenced to a base 1990 thematic mapper data set in a Georgia State plane projection. Changes between pairs of image dates were determined by automatic classification as well as manual interpretation. A time series visualization of the changes over time was created that dynamically showed the changes overlaid over the landsat imagery as they occurred with reference dates displayed.
