615 Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Application of MEIS-II multispectral airborne data and CIR photography for the mapping of surficial geology and geomorphology in the Chatham area, Southwest Ontario, Canada A.B.Kesik Department of Geography, University of Waterloo, Ontario, Canada H.George & M.M.Dusseault Department of Earth Science, University of Waterloo, Ontario, Canada ABSTRACT: The surficial geology of the Chatham area in southwestern Ontario has been manned using B&W nanchromatic, CIR air photographs and MEIS-II airborne, multispectral scanner imagery. The study shows that the application of multisensor and multispectral data offers significant advantages for the enhanced discrimination of surficial materials geomornhological features and aggregate exploration. 1 INTRODUCTION The manning of surficial geologv was promoted bv a shortage of aggregates in the rapidly developing Windsor-Toronto corridor in Southwestern Ontario. A multisensor approach was adopted for effective man ning in view of difficulties experienced by previous investigators in determining geologic unit boundaries with the aid of onlv black and white nanchromatic air photographs (E. Sado, oers. comm., 1984). Figure 1. Figure 1. Location of the study Area in southwestern Ontario, Canada The objectives of the studv were: 1. To compare photo-geological interpretations of nanchromatic and CIR air photographs with that obtained from digital analysis of multispectral data (MEIS-II). 2. To explore different models for Quaternary sedimentation likely to lead to the explanation of the origin of coarse aggregates within the study area based on a revised interpretation of the surficial geology. The fundamental hvnothesis was that multisensor remote sensing and related image analysis could provide an improved means by which scattered coarse fluvioglacial sediments, known to occur at shallow depths below the ground surface, could be detected and delineated. 2 STUDY AREA The studv area is 5 km east of Chatham, in SW Ontario and comprises 160 sq km of the physiographic unit known as Chatham Flats (Chapman and Putnam, 1984). Bedrock consists of Upper Devonian shale and occurs at a depth of approximately 23 m. The Ouaternary sediments overlying bedrock are associated with continental glaciation - till, proglacial sands and gravels and glacio-lacustrine sediments, mostly silts and clays. Deltaic sands are usually present as a discontinuous blanket at the ground surface. Potentially usable fluvioglacial sediments are masked bv fine textured glacio-lacustrine and deltaic sediments making aggregate exploration difficult. 3 DATA ACDUISITION The remote sensing data used for this study included the following’ 1. Black and white nanchromatic air photographs, 1:15,840 taken during late summer. 1978. 2. Colour Infrared (CIR) air photographs, 1:26,000 taken during Sprirg (May 85). 3. Multispectral scanner data from MEIS-II (Till et al. 1983) taken in May 1985. Spectral ranges of the channels are as follows; Table 1.

Analysis was supported by the ancillary information (maps, reports,relevant literature), and by field studies of surficial geologv and geomorphol ogy.
