Photo Interpretation of Vegetation. A Literature Survey to Determine the Capabilities of Existing Photo Interpretation Techniques of Evaluating Physical Properties of Vegetation

Abstract

The objective of this study, as stated in WESSE letter dated 15 April 1957 is to determine by survey of literature the applicability, capabilities and limitation of existing air photo interpretation techniques in determining certain physical properties of vegetation. The study concentrates on interpretation of tree and scrub stands with emphasis on measurement of trunk diameter and spacing, canopy height and coverage, density and height of undergrowth, and type of foliage. Quantitative values have been determined in so far as possible. When values can be determined only in a relative manner, this has been noted and analyzed. Determination of accuracy ef measurements as related to scale, photo characteristics, seasonal effects and light condition (time of day) is discussed.
