HYDROGRAPHIC MANUAL 



A condensed report shall be placed as an- 

 inset on the chart for unit reproductions for 

 field and office use. The report shall include 

 a general statement on the extent of the 

 review, and character of the area. Either a 

 statement or legend shall be included to ex- 

 plain chart markings. Each circle should be 

 numbered and its feature described under 

 the same number in the report, unless a 

 short notation beside the circle furnishes 

 adequate information. It is particularly 

 helpful during survey investigations if es- 



sential information on reported features is 

 included in the presurvey review. 



The presurvey review shall be dated and 

 signed, and inspected by the Chief, Hydro- 

 graphic Section. It will be filed for use dur- 

 ing final review of the new survey. Should 

 any important information affecting current 

 charting be revealed during the presurvey 

 review, the Chief, Nautical Chart Compila- 

 tion Section, shall be so informed for rea- 

 sons stated in 6-104.
