converted for numerical calculation by computer. Series of correction factors are given to 

 show the variation of the factor with different variables. The correction factor is shown to 

 vary in an elliptical manner about the center of the model with a minimum value at the 

 center. Convenience of using a digital computer to calculate the correction factor is 

 discussed. Author notes that there is not horizontal displacement of underwater features in 

 stereo models.

 Keywords: Aerial Photographs, Coastal Processes 



Article discusses basic requirements for shore process investigations, limitations of 

 conventional methods, and possibihties of using photos to supplement or replace 

 conventional study procedures. Qualifications of photogrammetry in coastal studies are 

 given, especially determination of underwater topography. Procedures for using photos to 

 study landforms, wave characteristics, currents, and littoral drift are discussed. Aircraft, 

 film, and lens requirements and problems in photogrammetry applications to shore 



processes are summarized. Pertinent literature is included. ^m-^.nc^r^^n^

Maritime Sediments, Vol. 1, No. 2, Apr. 1965, pp. 8-12. 



Keywords: Aerial Photographs, Coastal Changes, Nova Scotia, Canada 



Article describes use of comparative photos to determine changes at two locations along the 



coast of Nova Scotia. Two sets of photos dated 1945 and 1955 were compared for Rose Bay 



and four sets dated 1939, 1945, 1950, and 1960 were analyzed for Advocate Harbor. 



Directions of littoral drift and growth of spits and bars were determined from periodic 



photos. Availability of comparative photos and their potential for studies of coastal changes 



were emphasized.

Vol. 19, No. 4, 1965, pp. 372-381. 

 Keywords: Aerial Photographs, Coastal Changes, Nova Scotia, Canada 



Paper describes use of comparative photos to study changes in coastal features. Rose Bay 

 and Advocate Harbor, Nova Scotia were studied. Photos were used to examine sedimenta- 

 tion processes associated with wave and current action. The author concluded that photos 

 were useful for studying coastal changes and proposed a program to photograph the 

 Canadian coastline periodically to monitor the changes. The author maintained that this 

 would give results worth more than the cost.
