FORECASTING TRAFFICABILITY OF SOILS. AIRPHOTO APPROACH
Abstract
The study reported herein is part of a compre hensive effort, begun in 1949, to develop tech niques for estimating the trafficability of soil by remote means. It is devoted specifically to development of techniques for analyzing and inter preting vertical aerial photographs for soil trafficability purposes. To provide a basis for this study, airphoto and soil trafficability data were collected over a period of several years from 33 humid-climate states and 2 arid-climate states in the United States. This report de scribes the principles and procedures of air photo interpretation required to estimate the trafficability of soils, and summarizes data re ported previously in supplemental reports in a form suitable for use by personnel engaged in airphoto-trafficability analyses. Soil factors, slope factors, and obstacle factors, all perti nent to terrain trafficability, are discussed. Terrain is classified into various representative landscapes which are fully described in regard to regional drainage, topography, local erosion, natural vegetation, cultural practices, parent material, soil profile, and trafficability and cross-country movement characteristics. Pro cedures for airphoto analysis of trafficability are rigidly defined, and an example of photo in terpretation is given.
