Surveying with a camera

More than fifty years ago, cameras were first used for survey work. At present, it is usually the work of specialists, but there is considerable scope for using an ordinary camera on certain types of survey. The work described in this paper was in the nature of an experiment. To some extent the experiment was a failure, since it did not achieve all that a good photo-survey should. Several factors imposed limitations on the work: the weather and light were not favourable for photographs, and the short time available prevented a preliminary reconnaissance-. However, the success of the venture can be assessed from the results. A map of fair accuracy has been produced of an area previously unmapped, and a considerable amount was learned about the use of a camera and its limitations on such work.
