Recent (1990-2007) Anthropogenic Change within the Forest Landscapes of Nova Scotia. Edmonton, Alberta: Global Forest Watch Canada. 62 pp. Online_Linkage: www.globalforestwatch.ca Description: Abstract: 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.

The results of the change analysis are made available to decision makers and civil society to support the stewardship and conservation of Canada's remaining forests.
