Abstract
Considering the vastness of Nunavut, the paucity of regional-scale surficial geology maps for the territory, the significant expense of working in a remote region, and the increasing availability of affordable, remotely sensed data, it is timely to develop and test remote predictive mapping techniques for producing surficial geology maps. The goal of this remote predictive mapping project is to produce a surficial materials map, which will be used to expedite subsequent ground-based mapping and sampling. This paper describes techniques used to produce a surficial materials map for an area in northern Baffin Island using remote predictive mapping techniques with LandsatTMand digital elevation data. The predictive maps produced in advance of the field work (i.e. "ground truthing") were found to be approximately 50% accurate. To improve remote predictive mapping accuracy to at least 80%, high-resolution imagery may need to be included in the remote predictive mapping protocol.
