Abstract A landslide inventory was conducted along the Ohio and Mississippi rivers in the New Madrid Seismic Zone of southern Illinois, between the towns of Olmsted and Chester, Illinois. Aerial photography and field reconnaissance identified 221 landslides of three types: rock/debris falls, block slides, and undifferentiated rotational/translational slides. Most of the landslides are small- to medium-size, ancient rotational/translational features partially obscured by vegetation and modified by weathering. Five imagery sources were interpreted for land-slides: 1:250,000-scale side-looking airborne radar (SLAR); 1:40,000-scale, 1:20,000-scale, 1:6,000-scale, black and white aerial photography; and low altitude, oblique 35-mm color photography. Landslides were identified with three levels of confidence on the basis of distinguishing characteristics and ambiguous indicators. SLAR imagery permitted identification of a 520 hectare mega-landslide which would not have been identified on medium-scale aerial photography. The leaf-off, 35-mm color, oblique photography provided the best imagery for confident interpretation of detailed features needed for smaller landslides.

Remotely Piloted Aircraft

Early in 1982, B.C. Research began to evaluate the feasibility, advantages and limitations of using Remotely-Piloted Aircraft (RPA) to acquire aerial photography in environmental applications. Advantages associated with these aircraft include low costs, ease of operation, low noise levels, portability, safety and very low speed-low altitude capability. In the first phase of this program, a three-meter span fixed-wing aircraft was constructed from a commercial model kit and modified to carry a remotely-operated 35 mm camera system. In summer 1982, this system was used to acquire aerial photography in a variety of applications including forestry, pollution detection, wildlife habitat assessment, site mapping, publicity, wildlife inventories and shoreline mapping. Various operational limitations were encountered including difficulty of navigation and aircraft control, the fragility of the “model” airframe and its limited payload capability. These limitations are being addressed in Phase II of the program, during which a purpose-built airframe is under development, equipped with automatic flight controllers and emergency systems, and employing digitally-encoded radio signals for secure aircraft command. A black-and-white video camera installed in the airframe provides real-time imagery as an aid to navigation and photoframing.

Terrain Features

The accuracy obtainable from four types of aerial photographic film in the mapping and description of soil and terrain features was measured. Black and white film gave a soil mapping accuracy of 72% and was just as good as the color or infrared films for the description of specific terrain features in mountain lands. The accuracy of the soil map in the mountain lands and the description of terrain features in an alluvial valley increased to over 80% with the color film. Infrared film, both color and black and white, gave slightly more accurate soil maps in the valley. The use of a film like Kodak Special Ektachrome MS Aerographic Type SO-151 is recommended for future soil surveys. Black and white prints and color prints and transparencies can all be obtained from the same roll of this film type.

AbstractThis paper outlines selected remote sensing techniques and their application to civil engineering surveys.In BS 5930, emphasis has been placed on the interpretation of black and white aerial photography to provide information. However, other techniques such as true colour and false colour infrared photography, thermal infrared, radar and landsat satellite imagery may be useful in appropriate applications.
