Abstract:

The use of aerial photography in forestry is increasing by leaps and bounds. As in any new and expanding field, there are many challenging problems to be solved. There is a need for methods and techniques that are practical and easy to use. In this article the author attacks one of these problems; he offers a short-cut method of estimating the height of trees by measuring the shadows on aerial photographs. Information that can be obtained this way is frequently useful to foresters in estimating forest conditions before making ground surveys.
