carry-on package, costing approximately $50,000 per unit, 

 consisting of the HDRS suitcase, a standard computer monitor, 

 an accurate Global Positioning System receiver, and a mass 

 storage device, that could automatically record digital 

 hydrographic data continuously from any surface ship equipped 

 with standard depth-finding transducers. An engineering model 

 and documentation supporting acquisition of operational systems 

 are to be completed in September 1994. Routine operational use 

 could commence as early as 1995. The HDRS would be deployed 

 first on Navy surface ships that transit data-poor areas. This 

 concept could be expanded to increase data collection in U.S.- 

 controlled waters by placing suitcases on U.S. Coast Guard, 

 NOAA or other civil vessels. 



IV. Other DMA Products Serving the Oceanographic 

 Research Community. 



DMA has made other products available to the public 

 whenever circumstances permitted. Two recent digital products 

 of interest to the oceanographic research community have been 

 the World Vector Shoreline (WVS) and the Digital Chart of the 

 World (DCW) . The WVS currently presents the world's 

 shorelines, international land boundaries, and country names at 

 a nominal scale of 1:250,000. It is available on nine-track 

 magnetic tape. It is being upgraded to present that same data 

 at variable, reduced resolution scales and also to include 

 maritime boundaries, and will be made available on a CD-ROM. 

 The DCW, developed by DMA jointly with the United Kingdom, 

 Canada and Australia, and supported by NATO Cooperative Defense 

 Funds, is based on the 1:1 million scale aeronautical 

 Operational Navigational Chart series, and includes such 

 topographic information appropriate to that scale as roads, 

 railroads, power lines, cities, and international boundaries. 

 It is now available as a set of four CD-ROMs. Both WVS and DCW 

 have been well received by the scientific community as well as 

 by Defense and other federal agency users. These products
