In spite of great advances in theory and instrumentation in relation to aircraft, photography, and plotting, there exist many situations where simple equipment can be used to obtain aerial photographs and to intensify map detail from them. The theory, techniques, and costs of methods that have been developed for mapping plantation extensions by using vertical aerial photography from 70 mm and 35 mm film format cameras in light aircraft are described. The efficiency of the aerial method is compared with conventional field survey techniques, and it is shown that intensified maps can be obtained which are at least as accurate for a cost saving of up to 75 percent and a labor saving of 86 percent. It is concluded that similar quick, simple, and low cost methods could be used in many other applications, both within and outside the forestry sphere. /Author/
