This paper summarizes the results of an investigation aimed at evaluating the potential advantages of state-of-the-art airborne remote sensing for highway siting and planning tasks, specifically in wetlands areas.

The basic objectives of the study were to develop methodologies using remotely sensed data for mapping wetlands soils and drainage, to evaluate the relative merits and usefulness of the various methods developed, to generate a selection of output products from the remote sensor data for display to highway planners and photo-interpreters, and to provide recommendations for implementation of remote sensing techniques in the highway planning and siting process. To accomplish these objectives, remote sensor and ground truth data were acquired for selected test sites in Florida, Michigan, and Minnesota. One of several test sites in Michigan has been selected as representative of the study objectives and methodology.
