Digital Mapping, Charting, and Geodesy Analysis Program Technical Review ofVector Smart Map Prototypes 1 and 2

摘要

Currently under development by the Defense Mapping Agency (DMA), the Vector SmartMap (VMap) represents a significant step forward in digital mapping. This Vector Product Format (VPF) relational database is intended to digitally represent map sheets (e.g., Joint Operational Graphics and Topographic Line Maps) at medium (Level I) and high (Level 2) resolutions. In an effort to optimize Naval (meaning U.S. Navy and Marine Corps) usage of such data, the Digital Mapping, Charting, and Geodesy Analysis Program (DMAP) has evaluated VMap Prototypes 1 and 2 and has suggested modifications. The review of Prototype 1 consists mainly of a comparison with a similar DMA product, namely Digital Feature Analysis Data, which contains features that are missing from the VMap prototype. DMAP recommends the inclusion of these features in VMap. In Prototype 2, DMAP discovered multiple quality control errors, which were found by viewing data around Texas and Bolivia. Comparisons with another VPF product, Interim Terrain Data, led to the discovery of even more VMap inconsistencies. DMAP recommends that VMap remain in the prototype stage until all errors are rectified.
