Soil Mapping by Stereoscopic Interpretation of Airphotos1

  1. Jerome K. Pasto2

Abstract

Abstract

In many areas it appears possible to map soils, with some generalization, by combining stereoscopic interpretation of aerial photographs with field checks. As a test of this technique, the soil series were mapped on 4000 acres in the glaciated region of southern New York. The area was then mapped on foot in the usual manner. The stereo results came remarkably close to representing the true field conditions.

Essentially the method relies on knowledge of the kinds of soil which occur in the area, then identifying certain features of the land related to soil patterns. The major features on airphotos important to soil identification are the landscape or land form, slope, position, color tone, vegetation, drainage pattern, and land use.

In complex areas soil mapping obviously depends on field examination, but where stereo methods can be applied more maps could be made available for use, with a big saving in time and money.
