Course Summary

This course provides guidance on the required geodetic reference datum's and coordinate systems for USACE navigation and flood control projects. General guidance is also provided on setting survey control for dredging projects and positioning aids to navigation in these projects. The major emphasis in this course is on vertical reference datum's for navigation projects--tidal, river, lake, pool, and flood control reservoirs. This course has minimal coverage of horizontal coordinate systems, horizontal datum's, and control survey methods since this material is fully covered in other engineer manuals listed in Appendix A. In addition, nearly all hydrographic surveys and dredge positioning are now controlled by established, nationwide DGPS networks; thus reducing the need to establish supplemental horizontal control on dredging and navigation projects.
