Title: System in Photogeology

Author(s): Ronald R. Hartman (2), Kalman N. Isaacs (2)


In the study of features that have been modified by a succession of geologic agents or events, the simple matching of photos becomes inadequate, and the aerial photos must be studied and analyzed in a systematic manner.

The method by which a photo may be described in terms of its topography, drainage and erosion, tone, and vegetative cover is described and their significance is discussed.

Land forms, and their photographic aspects, are discussed under the broad headings of sedimentary rock features, igneous rock features, metamorphic rock features, features developed on unconsolidated materials, and structurally controlled features.

A few examples are given to illustrate the method.
