SUMMARY AND CONCLUSIONS 



The SYNBAPS data base was designed to meet the specific 

 and immediate need for bathymetric profiles for acoustic 

 modeling. However, properly used, it offers many applications 

 beyond its preliminary designs. 



Often in naval planning as well as in naval operations, 

 speed is as important as accuracy when information is needed. 

 SYNBAPS is not ideally suited to hydrographic charting because 

 some high-frequency information is lost, but it provides very 

 rapid responses. SYNBAPS has these additional features: 



• Only data points are stored in the data bank, 



• The locations of data points are logically structured 

 on a Mercator projection by 5-minute intersections, 



• Random access to the data is by large blocks (5- 

 degree square) , 



• The data bank is updated by replacing blocks of data, 



• The size of the data bank is fixed once it has been 

 created for any ocean area, 



• Classified survey data, in chart form, can be incor- 

 porated in the data base with no compromise of 

 security, 



• Highly compacted forms of the accessing program and 

 the data bank can be used on shipboard.
