The aim of this study was to develop a database of landscape metrics that could be used to rank the rivers in relation to potential salmon productivity. The AA. examined the rankings in relation to existing empirical (monitoring) data describing
productivity of salmon stocks. To extract the metrics for each river basin they used a digital elevation model and multispectral satellite imagery. They developed procedures to extract channel networks, floodplains, on-channel lakes and other catchment features
