AbstractRemote predictive mapping (RPM) of surficial earth materials in the Wager Bay North Area [NTS 046E (N), 046K (SW), 046L, 046M (SW), 056H (N), 056I and 056J (S)] was undertaken as part of the Geo-mapping for Energy and Minerals (GEM) Melville Peninsula Multiple Metals Project. A mosaic comprising seven separate LANDSAT TM 7 images was prepared for the classification of surficial materials. Training areas representative of 12 surficial material classes were identified through the use of airphoto interpretation, LANDSAT imagery and field knowledge of the mapping area. The statistical separability of the training areas with respect to spectral reflectance was evaluated using transformed divergence analysis. The Robust Classification Method (RCM) was used to classify the LANDSAT imagery producing a number of predictive maps of surficial materials. These maps were statistically analysed via a confusion matrix and associated measures of accuracy, then geologically evaluated through the use of airphotos in concert with field observations. The mapping of surficial materials using LANDSAT data is not without problems but does generate useful predictive maps that serve to focus and guide more detailed field mapping studies as well as providing information on surficial materials in extensive areas that cannot be field mapped. Incorporation of field knowledge and the expertise of Quaternary geologists are critical to the production of predictive maps of surficial materials through the entire remote predictive mapping process.
Summary(Plain Language Summary, not published)
Surficial materials left by the retreat of the last glaciers were mapped in a region north of Wager Bay near the community of Repulse Bay, central mainland Nunavut. The surficial materials maps are based primarily on the interpretation and classification of remote sensing data with some data acquired during fieldwork. The work was undertaken to provide new geological knowledge of the distribution and nature of surficial materials to guide field investigations and will support informed decision making for resource development and land use. The accompanying report discusses the remote predictive mapping method used to produce the maps and its effectiveness in this region. This work is part of the Melville Peninsula Project at the Geological Survey of Canada, as part of Natural Resources Canada¿s Geo-mapping for Energy and Minerals (GEM) Program.
