Aerial photographs enhance forest mapping and timber estimates, suggesting broader potential across regions.
The great use of aerial pictures in forest surveys is not as highly appreciated among foresters as their value warrants. With their increasing availability, methods of mapping and timber estimating are being radically changed. The following outline of this new development was given in a talk at the Yale School of Forestry, February 22, 1935. While it is based on the use of pictures in the northeastern spruce region, they have a wide application to other forest regions as well.
