Abstract
Generic information on DCW (Digital Chart of the World) data sets :- The primary source for DCW is the US Defense Mapping Agency (DMA) Operational Navigation Chart (ONC) series produced by the United States, Australia, Canada, and the United Kingdom. The ONCs have a scale of 1:1,000,000, where 1 inch equals approximately 16 miles.The charts were designed to meet the needs of pilots and air crews in medium and low altitude en route navigation and to support military operational planning, intelligence briefings, and other needs. Therefore, the selection of ground features is based on the requirement for rapid visual recognition of significant details seen from a low perspective angle. The DCW database was originally published in 1992. Data currency varies from place to place depending on the currency of the ONC charts. Chart currency ranges from the mid 1960s to the early 1990s. Compilation dates for every ONC chart are included in the database. For more information on the Digital Chart of the world please browse the DCW Internet Site http://www.maproom.psu.edu/dcw/ where you can download these data in VPF format. GA has converted these VPF format files to common GIS formats Arcview and Mapinfo available at www.ga.gov.au/geoscience/national on the download page. Available datasets include drainage, roads and railway networks, political areas and boundaries and population centres.
