A RADARSAT ScanSAR-Wide image (acquired Feb. 14, 1996) illustrates the route taken by the Expédition Mobilité Satellite au Pôle Nord Magnétique from March 26-May 14, 1996. The image was received by the Canada Centre for Remote Sensing (CCRS), processed by RADARSAT Interna-tional, and geocoded and enhanced by CCRS. To meet the requirements of the expedition, three portions of the image were supplied at a scale of 1: 750 000 with the addition of coastline data and a general ice interpretation. The explorers' first-hand field interpretation of the image information resulted in these image maps becoming essential to the expedition's success. The lower inset depicts explorers Marc Fafard (l) and Yvan Désilets (r) enroute from the community of Resolute, Northwest Territories, Canada, to their destination at the Magnetic North Pole (upper inset). The image was initially requested by the Canadian Ice Service of Environment Canada in support of their winter reconnaissance of ice conditions in the Canadian Arctic.RADARSAT image © Canadian Space Agency, 1996.

1353 Revised Mapping of Lava Flows on Mount Etna, Sicily
Michael Abrams, Remo Bianchi, and Dave Pieri

Airborne remote sensing data of Mt. Etna helped to resolve conflicts for the ages of lava flows that were based either on paleomagnetic measurements or the historical record. 

1361 The Use of Satellite and Airborne Imagery to Inventory Outlet Glaciers of the Southern Patagonia Icefield, South America
M. Aniya, H. Sato, R. Naruse, P. Skvarca, and G. Casassa

With the aid of stereoscopic interpretation of aerial photographs and digital enhancement of the Landsat TM image, glacier divides were located and glacier drainage basins were delineated. 

1371 Applications of Spectral Stratigraphy to Upper Cretaceous and Tertiary Rocks in Southern Mexico: Tertiary Graben Control on Volcanism
Pamela E. Jansma and Harold R. Lang

Seven spectral stratigraphic units, each of which corresponds to a distinct lithostratigraphic unit, were delineated. 

1379 Remote Mineralogic and Lithologic Mapping of the Ice River Alkaline Complex, British Columbia, Canada, Using AVIRIS Data
Timothy L. Bowers and Lawrence C. Rowan

The data were first calibrated to relative reflectance and then used to spectrally map mineralogies in the study area by using a linear spectral unmixing program. 

1387 Waste Site Characterization through Digital Analysis of Historical Aerial Photographs
Paul Pope, Ed Van Eeckhout, and Cheryl Rover

The historic images were rectified, coregistered, and transported to a GIS where boundaries of features such as trenches and disturbed soil were extracted. 

1397 Use of Digital Image Analysis and GIS to Assess Regional Soil Compaction Risk
M.L. Bober, D. Wood, and R.A. McBride

Spatial information on the distribution of various agricultural crops in relation to the major soil association was acquired using an integrated approach involving digital image analysis and GIS.
