Design and Implementation of the Digital World Vector Shoreline Data Format

摘要

This report defines the data structure and format that NORDA designed for the Defense Mapping Agency's (DMA) digital World Vector Shoreline (WVS) data set. Methods of accessing the data set, current and future applications for WVS, and suggested future additions to the data set are also discussed. Applications and suggestions are based on responses to a questionnaire prepared by NORDA to survey DoD users who evaluated the latest WVS prototype. NORDA's role in designing the WVS data format and structure was a direct result of our recommendations to DMA on their original WVS prototype data set and format, presented in NORDA reports 146 and 154. In these reports, NORDA recommended that specific changes be made to DMA's original WVS to be sure that it would meet Navy requirements for a digital global shoreline map. In response, DMA requested that NORDA assist them in the design and implementation of a new WVS format and data structure. This new product was completed and distributed to potential Navy and other DoD users in March 1987. Keywords: Shores, Data management, Data bases, Digital maps, Computer applications. (edc)
