Photo Interpretation of Vegetation and Soils in Wild Land Areas of California¹

ABSTRACT

Through stereoscopic study of aerial photographs many features of the vegetation and also ground features can be directly identified. This has a practical application in mapping vegetation and soils in upland areas of California. This paper describes how vegetation types can be identified by analysis of the features visible on aerial photographs. It then describes how soil mapping is facilitated by photo interpretation of ground features, land form, and vegetation.
