Limited helicopter-supported field work combined with the examination of archival information (Riley and Boissonneau (unpublished field notes and photographs); Geological Survey of Canada, Operation Winisk unpublished field notes; Skinner 1973; Sanford, Norris and Bostock 1968; Sanford and Norris 1975; and Thorleifson, Wyatt and Warman 1993, and their unpublished field notes) provided the ground control on the classification of objects. In addition, information from the various other Far North Information Knowledge Management Program projects, such as base data and land cover information (Ontario Ministry of Natural Resources, in progress), has been used in the interpretation and classification of the surficial materials. 5705000 m ! ! ! SPOT imagery (4 colour bands and the panchromatic band), a digital elevation model and its derivatives and the Ontario Hydro Network vector drainage shape files (Ontario Ministry of Natural Resources 2010) are the primary data sources for this remote predictive mapping exercise. A multiresolution segmentation algorithm, using different image layer weights, scale parameters and homogeneity criterion, within an objectbased image analysis software is used to achieve meaningful objects representing various surficial material types. Objects are then classified based on digital signature, internal variability of signature and proximity to certain vector layers and certain adjacent material types. 500000 m 51°30′00″ 55′ 05 ! In 2008, the Ontario government announced plans to permanently protect half of the Far North region of Ontario and launched a planning process to support this goal (Far North Information Knowledge Management Program). During the initial stages of planning, the need for primary landscape data became apparent. A terrain mapping project to remotely predict surficial materials was initiated by the Ontario Geological Survey in response to this information need. 81°00′00″ !
