Hydrography and the Engineer
Publication: Journal of the Surveying and Mapping Division
Volume 99, Issue 1
Abstract
Engineers working offshore need accurate hydrographic information. A large amount is already available in the charts. Sailing Directions, and tide tables published by national hydrographic offices; considerably more exists as the results of the surveys on which the charts are based. The engineer needs to be able to evaluate the suitability of this information for his own purposes, so that he may decide whether a resurvey is warranted. Some of the factors bearing on this evaluation are also presented. Hydrographic surveys conducted for navigational purposes have limitations for the engineer of which he should be aware. Should he decide on a resurvey, the project should be reviewed with the hydrographer and specifications jointly agreed; some factors to be considered are listed.
