Boydell Geological Survey of Canada i steep erimental ABSTRACT drainage ve Preparation of pre-field program maps for terrain mapping in Canada*s north requires large amounts of time spent in conventional airphoto analysis. Multispectral analysis of ERTS-1 data provides a potent ially more rapid and relatively accurate alternative. Training sets for automated terrain classification were devised using the Bendix n: .Ltd. Multispectral Analyzer Display unit, for an area near Pelly Bay, N.W.T. A map of the distribution of surficial deposits was compiled from field checking and compared to the ERTS map. There was good agreement, generally, between both the boundaries of the terrain Unwetter nabtrag units and the materials, except where they were confused by vegetat ion differences. Reclassification of the ERTS map, using the ground data, permittee separation of the vegetated surficial deposits on the basis of differences in their related plant communities. & Co. Results indicate that automated classification of ERTS data is a Dil Ero- useful means of generating preliminary terrain maps for use in a field checking program. This conclusion is subject to the provision that only a small area was examined and that further research is required to test the validity of the technique, and its application in other parts of the Canadian Arctic. d in der für Bad INTRODUCTION Techniques of analysis of ERTS-1 data commonly fall into two broad classes: those which are concerned with the visual inter noff pretation of photographic imagery derived from multispectra 1 data, and those which use automated methods for multispectra 1 analysis. Among the projects of the Terrain Sciences Division of the Geological Survey of Canada are several concerned with the small scale mapping of land forms, deposits, and permafrost phenomena in the Canadian Arctic. These are part of an ongoing, systematic map ping program of the Division and are designed to provide a geologic al data base for land use planning and various aspects of engineering .n a soil construction in the north. Preparation for projects of this type requires the compilation of preliminary terrain maps for use in the field checking program, from large numbers of high altitude air photographs. OBJECTIVES The principal objective of this evaluation was to deter mine the extent to which a pre-field program terrain map of an area of the Arctic could be produced by rapid and relatively accurate
