Nova Scotia Change Analysis, 1990-2007

(2009-06-25) Anthropogenic Change analysis was performed in Nova Scotia using Landstat TM imagery between the approximate time periods of 1990 and 2007. Changes were detected using a simple image differencing technique between Band 5 of temporal image pairs at a user specified change threshold. The detected change was converted to vector format and visually analyzed to identify anthropogenic changes and digitize changes not detected by the image differencing process.
