1920 Aerial Photography of the Atlantic Coast of New Jersey from Cape May to Sea Bright and Sandy Hook, United States of America

Title:: 1920 Aerial Photography of the Atlantic Coast of New Jersey from Cape May to Sea Bright and Sandy Hook, United States of America
Abstract:: These are black and white aerial photographs of the Atlantic coast of New Jersey. Photograph date is believed to be March 1920, based on hand-written notation on some of the storage envelopes and other sources. In addition, photo 012 shows Turtle Gut Inlet to be open, and the inlet closed naturally in 1921. Sandy Hook photographs, nos. 201-211, may be a later date. Source of paper prints: photographic archives of the Beach Erosion Board (predecessor of the former Coastal Engineering Research Center), presently stored at the Coastal and Hydraulics Laboratory, Engineer Research and Development Center, in Vicksburg, Mississippi, USA. Print condition: variable. These prints look like they were made quickly because many of the negatives are crooked on the photographic paper. Most are low contrast and show fading and discoloration. Printed on single-weight glossy paper. The printing date is unknown.
Supplemental_Information:: From the Annual Report of the Director, U.S. Coast & Geodetic Survey June 30, 1920 (p. 88): "In March 1920, the Army Air Service photographed the coast line of New Jersey from Cape May to Seabright. A single flight was made, using the k-1 camera. The plane flew at an altitude of 10,000 feet, and under very good air conditions. The camera was mounted in gimbals, with a lead weight at its lowest point to assist in maintaining the optical axis of the camera in a vertical position. Level bubbles were placed on the camera to aid in keeping the camera in the proper position. The photographs are being used to revise the charts of the coast of New Jersey. The individual photographs are 18 x 24 cm. in size, and the approximate scale is 1:10000. The photographs are mounted in strip mosaics, for convenience sake, not over 4 feet in length. The length is generally determined by the position of control points. This composite photograph is compared with the topographic sheet of the same area and control points identified. The scale of the photographic mosaic is determined, and by means of pantograph the data are reduced to the scale of the chart and transferred from the photographs to tracing paper." "The photographing of the 120 miles of coast line took less than 2 hours time in the airplane. The development of the films and printing took 2 days’ time of one man. Two rolls of film were used, a total of 183 photographs. The work of interpreting the photographs, assembling mosaics, comparison with topographic sheets, and reduction to the scale of the chart of the outside shore line required 15 days office work by one engineer."
