The attribute adjacency matrix is a fundamental component of many metrics used to characterize landscape heterogeneity from land cover land use maps. Since it quantifies adjacent pixel class co-occurrence, it is unsuited to detect broader-scale struc

The landscape of Alberta’s oilsands regions is undergoing extensive change due to the creation of infrastructure associated with the exploration for and extraction of this resource. Since most oil sands mining activities take place in remote forest

Cloud shadows in satellite imagery hinder understanding of ground surface conditions due to reduced illumination and the potential for confusion with illuminated low-reflectance objects such as water bodies. This paper extends the application of the
