SOFTCOPY PRODUCTION 
DMAAC is escalating the automation of the charting process and expects to 
achieve an all digital softcopy production capability by 1988 (Fig 2) to include 
the establishment, as appropriate, of uniform procedures relating to the 
collection, screening, evaluation, editing, symbolization, retrieval and exchange 
of digital source and production data. It is anticipated that the concept of 
digital color separation and data base development will necessitate some monor 
changes in product specifications and compilation procedures. Existing charting 
specifications for DMA products were developed in an era devoid of 
automation. These specifications need to be reevaluated for redefinition of 
certain cartographic rules to maximize the savings that are possible through 
automation while maintaining effective communication to the users. 
Table 2 lists currently identified developmental efforts to support this proposed 
softcopy production system.
