There too. But how about the more obscure data types - Lighthouse, Fish Farm, Cease-Fire Line, Oasis, Wharf, Communication Tower ? All there as well. You can even find out where the cranberry bogs are located in your area ! Interested ? then read on...

Vector Map (VMap) Level 0 is an updated and improved version of the National Imagery and Mapping Agency's (NIMA) Digital Chart of the World (DCW®). The VMap Level 0 database provides worldwide coverage of vector-based geospatial data which can be viewed at 1:1,000,000 scale, i.e. 1cm=10km. It consists of geographic, attribute, and textual data stored on CD-ROM or as downloaded files. The primary source for the database is the 1:1,000,000 scale Operational Navigation Chart (ONC) series co-produced by the military mapping authorities of Australia, Canada, United Kingdom, and the United States. The complete database is available on a set of four CD-ROM's and contains more than 1,800 megabytes of vector data organized into 10 thematic layers. The download version comes in 4 zipped files, with a total filesize of 925 megabytes. VMap Level 0 includes major road and rail networks, hydrologic drainage systems, utility networks (cross-country pipelines and communication lines), major airports, elevation contours, coastlines, international boundaries and populated places. VMap Level 0 includes an index of geographic names to aid in locating areas of interest. VMap Level 0 is accessible directly from the CD-ROM or can be transferred to a hard drive and used in many geographic information system (GIS) applications, including a number of free ones.
