This manual provides technical guidance for performing hydrographic surveys that support the planning, engineering design, construction, operation, maintenance, and regulation of navigation, flood control, river engineering, charting, and coastal engineering projects. Accuracy standards and quality control criteria are defined to establish US Army Corps of Engineers (USACE)-wide uniformity in performing surveys involving dredging measurement, payment, and acceptance.
This Book Presents A Systematic And Contemporary Treatment Of The Theory And Applications Involved In Higher Surveying. It Also Highlights Some Of The Modern Developments In Geomatics.After Explaining The Basic Survey Operations, Triangulation And Trilateration, The Book Describes The Various Adjustment Methods Applied To Survey Measurement In Detail, Which Is Followed By Topographic, Hydrographic, Construction, And Route Surveying. As Engineers And Surveyors Need Knowledge Of Determining Absolute Coordinates Of Points And Directions Of Lines On The Earth'S Surface, A Detailed Discussion On Field Astronomy Is Presented In This Book. A Chapter On Map Projection Is Also Included In The Book.Re...

This same principle may also be employed upon a smaller scale, substituting a boat for the ship. 125. A diagram of triangulation illustrating the arrangement of main and secondary stations in a hydrographic survey is given in Plate I. A study of this will give a clear idea of the objects to be sought in choice of stations; particular attention should be pai...
Excerpt from Elements of Hydrographic Surveying The object in view in the preparation of this work has been to furnish a text-book for the instruction of midshipmen at the U. S. Naval Academy; as a consequence, the subject has been treated with particular reference to the requirements of the course at that institution. The limitation thus placed has prevented the detailed description of certain features occasionally involved in surveying operations of the most precise nature, as, for example, astronomical transit observations; but all branches of the work connected with a marine hydrographic survey as ordinarily carried out have been completely described, and the book is therefore available ...
