Wainwright, D.B., Appendix No. 1903 - 6. Pp. 1005-1010. Channel and Harbor Sweep. (This technique, which was perfected within the Coast and Geodetic Survey as wiredrag, involved towing a long wire between two vessels suspended by buoys at a preset depth. If the wire encountered an obstruction, it would "hang" and as the boats progressed ahead the buoys would form a "V" pointing to the obstruction. Primitive forms of this method were mentioned as early as the 1850's in Coast Survey reports. See Appendix 1857 - 13. This method was first formulated by French hydrographers and further developed by the United States Lake Survey under the Army Engineers prior to adoption by the Coast and Geodetic Survey. Literally hundreds of unknown obstructions and dangers to navigation were discovered by this method prior to the development of reliable, highly accurate sidescan sonar systems.

Steel tapes, which were introduced in the late 1800's for precise geodetic surveying, had high coefficients of expansion and were used during the more stable night-time temperature hours for base line measurement. Invar was a material with a very low coefficient of expansion which allowed the measurement of bases during the day. Distance measurement techniques did not experience another major improvement until post-World War II with the modification of electronic aircraft navigation systems for precise distance measurement.)
