PHOTOGEOLOGY is the name given to the use of aerial photographs in geological studies. Aerial photographs are a source of geological information that may be unobtainable alsewhere. If the fullest use is to be made of this information for the purpose of geological mapping, there must be a planned integration of the photogeological word with the field and laboratory investigation. This book outlines a method by which this may be achieved. It includes, amongst other thing, a discussion of: (a) the geological interpretation of aerial photographs ; (b) the compilation of those interpretation on to maps; (c) the use of aerial photographs in the field, and (d) the use of aerial photographs for the production of the final geological map. I hope that it will be of value to all those concerned with the earth sciences whose training includes an elementary knowledge of geology. The term "regional mapping", as used in this book, means the mapping of large areas. The use of aerial photographs in the field and for compilation purposes is discussed from the poin of view of a geologist respontsible for mapping a large area in a short time. I believe that many of the suggestions made, particularly those concerning field work, will also be of value to geologists mapping in a more detailed manner. I have not hesitated to include personal opinions that many require qualifyng in the future. It is seldom possible to prove conclusively a photogeological point by a limited number of correlations between stereopairs an the corresponding field outcrops. If photogeology is to advence, geologists must be prepared to publish opinions and make generalizations based on their own experience with the photographs in the field. Other geologists may then amend the generalizations as a result of further field experience with photographs in different geological environment. Thus, progress will be made.
