Deforestation and forest harvest mapping with integrated automated and manual methods : pilot study Prince George, British Columbia, Canada / D. Leckie … [et al.].: Fo143-2/438E-PDF
The publication describes a pilot study that helped provide foundation information and insight to develop the methods used in Canada’s National Deforestation Monitoring System. All forest harvest and deforestation from 1990 to 1999 was mapped using Landsat satellite imagery for a 14,000 km2 area centred at Prince George, BC. The deforestation in the region is one of the more difficult types to map, whereas forest harvest was mostly simple rectilinear clearcuts. The pros and cons of automated classification, provincial inventory data and manual interpretation were determined and detailed accuracy assessments done. It was determined automated techniques were good for clearcuts, but insufficient for deforestation mapping. For deforestation mapping, the importance of ancillary data, high resolution imagery, quality checks, and review of deforestation events during subsequent mapping periods was demonstrated. The forest harvest and deforestation product has been and is being used to test spatially explicit carbon accounting techniques and contributed numbers to Canada’s deforestation estimates. The report is a vehicle to document an example of the detailed studies conducted to develop and prove Canada’s deforestation mapping procedures.
