wave -pattern maps showing direction and period. Several maps are presented. Visual 

 observation was superior to photos because of uncertainties in orientation and interpre- 

 tation of the photos, the small area included in each photo, and the need to observe for 

 several minutes to determine direction and period of smaller wave trains. Aircraft location 

 was by radar. Study covered an area off southern California. AppUcations of wave-pattern 

 maps are discussed; the influence of offshore islands on wave patterns is described.

Text is widely used in photo interpretation. First part covers principles of photo 

 interpretation, and describes elements of the photo pattern. Second part describes 

 procedures for interpreting various landforms and soils. Third part covers appHcations of 

 interpretation techniques to engineering, water resources, geolog)', and other fields. Chapter 

 5 discusses color (gray) tones of beaches composed of materials with different gradations 

 and predominant sizes. Text indicates that tone is a function of surficial moisture content 

 and predominant grain size. Effect of beach slope on gray tone of the beach is also 

 discussed. The book is a comprehensive compilation of basic information.

Although this article does not describe a remote sensing technique, it does discuss terrestrial 

 photogrammetry in the study of coastal processes. Capabilities of terrestrial photo- 

 grammetry in studying shoreline changes compared to aerial photogrammetry are outlined. 

 Terrestrial pliotogrammetry has been useful in measuring bluff recession, determining beach 

 profiles, and calculating volume changes. Ground pliotos were also used in the laboratory to 

 monitor changes in model beaches in a wave tank. Obtaining photos during bad weather and 

 collecting beach material samples, are particular advantages of terrestrial photogrammetry. 

 The technique is best adapted to small sections of coasthne.

Report covers techniques for interpreting landform and rural cultural features of glaciated 

 areas in the United States from photos and contains brief sections on photo identification of 

 shore features associated with glacial landforms and seaside resort settlements, primarily in 

 Massachusetts. Several shore features are illustrated by black and white stereopairs and
