Metadata for Digital Topographic Maps of Vietnam

要旨

The topographic map is considered as a very essential document, and used as the base map for any geographical application. Presently, in Vietnam the information about data (metadata) of digital maps not yet designed and built up in an adequate and sufficient way. Consequently, end-users are facing with many difficulties when using digital topographic maps. Further, this results in the difficulties in keeping of digital topographic maps up-to-date and in distributing topographic information efficiently. To solve the above problems, our research proposes a metadata standard for Topographic Maps of Vietnam, as well as providing a metadata management tool to facilitate the process of gathering, managing, distributing metadata related to Vietnam topographic maps.
