Report discusses production, maintenance, and revision of nautical charts by the USC&GS 

 using photogrammetry. Types of photos used are described along with shorehne delineation 

 techniques. Field inspectors frequently mark the high water line on photos by referring to 

 debris lines or other markings to aid the chart compiler. Black and white infrared photos 

 malce water areas appear very dark and permits shorehne delineation with less field 

 inspection.

Article describes a project by the USC&GS for the Corps of Engineers to dehneate the 

 shorehne at low- and half-tide levels as part of a tidal power study. Cobscook Bay has an 

 irregular shoreline with numerous tidal flats. Photos were taken simultaneously using 

 panchromatic and black and white infrared film at low tide and half tide. The infrared film 

 was ideal for the task since a thin film (3 inches or less) of water photographed very dark or 

 black in marked contrast with the adjacent land areas. Time of photography and tide level 

 were correlated from tide observations at several stations within the bay. A panchromatic 

 and an infrared photo illustrate a part of the area.

Report describes a program to obtain photos of the Eastern United States coasthne by 

 scientists at the Woods Hole Oceanographic Institution. Vertical photos were taken of parts 

 of the coast for making mosaics of coastal features and obUque color photos of the entire 

 east coast were taken at a rate of two frames per second with a movie camera. This article is 

 primarily concerned with oblique photos, and discusses the equipment and procedures used. 

 Changes in coastal features over about a 6-month period are illustrated for Fire Island Inlet, 

 New York, and Capes Hatteras and Fear, North CaroUna. Coastal changes are described in 

 qualitative terms because of the difficulty of extracting quantitative data from the oblique 

 photos. Users and uses of such photos are discussed. The group planned to continue the 

 flights, at least annually.
