the beach. Rip currents were identified on the photos by gaps in the breaking waves and by 

 areas of discolored water or foam being carried seaward. Photos were used primarily to 

 examine the characteristics of the water rather than land features.

 EARDLEY, A. J., Aerial Photographs— Their Use and Interpretation, Harper and Brothers, 

 New York, 1942, 203 pp. 



Keywords: Aerial Photographs, Geological Applications, Coastal Mapping 



This is an early textbook on photo interpretation containing basic concepts of making 

 measurements on photos. Principles of stereo viewing and procedures for constructing 

 mosaics are described. Much of the book is devoted to the applications of photo 

 interpretation in geologic mapping. A brief section, by John B. Lucke, on the use of photos 

 in shoreline studies is included. Advantages and limitations of photos in examining coastal 

 features are discussed. Primary advantage of photos is noted as their depiction of submerged 

 features such as channels and sediment deposits. The best time and weather conditions for 

 taking photos showing underwater detail are described. Mosaics of two coastal areas show 

 intricate submarine sedimentation patterns. Techniques for identifying submerged features 

 are presented.

Keywords: Aerial Photographs, Geological Applications, Coastlines 



This is an early textbook on photo interpretation. Emphasis is on geological appUcations of 

 photos, although several engineering applications are discussed. Procedures for measuring on 

 photos, stereo viewing, and mosaic construction are described. Section on coastal landforms 

 presents techniques for the geological classification of coastlines from photo interpretation. 

 Photos of coastal landforms are included.

 U.S. NAVAL PHOTOGRAPHIC INTELLIGENCE CENTER, "A Guide to Pacific Land- 

 forms and Vegetation for Use in Photographic Interpretation," Report No. 7, U.S. Naval 

 Photographic Intelligence Center, Washington, D.C., May 1945. 



Keywords: Aerial Photographs, Coastlines, Coastal Mapping, Geological Applications, 

 Vegetation 



Report describes landforms and vegetation typical in the Pacific. The report served as a 

 training guide for interpreters to identify landforms and vegetation from photos. Emphasis 

 is on coastal landforms, coral reefs and atolls. Many coastal features are illustrated by 

 stereopairs. Many oblique and ground photos with descriptions of important features are 

 included. Material may be useful to coastal engineers not familiar with photo interpretation 

 techniques. Report can be used in geological applications.
