The Exploitation of Digital Data through Electronic Displays.
Abstract
Display technologies and database capabilities are now mature enough to support producing electronic charts (EC) at the Defense Mapping Agency (DMA). The ultimate success of (EC) will depend upon proper identification and validation and of standardization of product digital data requirements prior to actual system development. Digital data in a universally accepted standard format will provide (DMA) the capability for greater flexibility and increased responsibilities of the output device. Resolution constrains symbology and textual display designs. Electronic charting, However, expands the possibilities for symbolization and display manipulation. The capability for exploitation of a digital data base in conjunction with these dynamic (CRT) displays will allow customized presentations geared directly to user needs. The dynamic capability for interacting with and changing the display contents can also pose dangers to users with non-cartographic backgrounds since inadvertent user manipulation and deselection of specific data (SETS) could contaminate the user perspective designed into the total (EC) product and subsequently promote erroneous interpretation of the data. Finally, a critical component in support of new planning, navigation, and guidance systems is the ability for (DMA) to actually provide adequate digital databases containing the required (MC&G) information optimized for electronic displays. Ultra-high resolution databases will be required in the 1990's with additional descriptors and resolutions.
