Each dataset includes a metadata (.xml) file providing complete documentation, as well as an ArcGIS layer (.lyr) file displaying symbols and classifications for the dataset when viewed in ArcGIS. Each SDC file also includes a projection (.prj) file storing the coordinate system information that is used by ArcGIS. Map document (.mxd) and group layer (.lyr) files are included for all geographic areas to provide symbolized maps of the datasets. Published map (.pmf) files that can be viewed with ArcReader are also included for all geographic areas.
Data & Maps 2006 is organized on five DVDs. The Data & Maps and StreetMap USA DVD contains the StreetMap USA dataset as well as the Data & Maps vector data. The other four DVDs include all of the elevation and image datasets. One of the four contains the 90-meter Shuttle Radar Topography Mission (SRTM) Global Digital Elevation Model with all of the void areas filled, as well as many other worldwide elevation and image datasets. The remaining three DVDs contain regional data for: a) North and South America, b) Europe and Africa, and c) Asia and Australia. Each of these regional DVDs includes global imagery captured at 150-meter resolution, as well as shaded relief derived from the SRTM Global Digital Elevation Model. In addition, all five DVDs contain the Data & Maps HTML-based Help system.
This data is useful for general purpose basemaps and for more specific uses. The data can make a new user productive and the software useful as soon as it is installed. General basemap information is available for the world, Canada, Mexico, the United States, and Europe. The significant basemap layers included are boundaries, cities, rivers, and roads. In addition, where possible, demographic data is provided for subnational boundaries such as states, counties, or their equivalents.
Each dataset is fully documented with metadata, which furnishes extensive general and technical characteristics of the dataset. The metadata provides unique identification, description, content, purpose, status, accessibility, creator, publisher, data quality, condition, spatial data organization, spatial reference, entity and attribute descriptions, distribution, and metadata reference information. The metadata also displays a "thumbnail," which is a small, graphic image of the dataset. The metadata uses the Content Standard for Digital Geospatial Metadata from the Federal Geographic Data Committee (FGDC). The metadata is a file provided for each dataset in Extensible Markup Language (XML) and HyperText Markup Language (HTML) formats. The Data & Maps 2006 metadata in XML can be viewed in ArcGIS and can also be used with the ArcIMS Metadata Server. The metadata in HTML can be viewed in any HTML browser.
