ArcWorld Supplement

Data Description | Data Location

Released in March 1996, ArcWorld Supplement updates some of the maps in ArcWorld 1:3M and adds several new maps, too. All the maps in this newest database take advantage of the improved data model introduced with ARC/INFO Version 7 (i.e., region and route subclasses). This means, for example, that the Countries coverage contains separate, easy-to-display maps for countries, states, continents, seas, and so on. All the maps come in shapefile format as well.

The following ArcWorld maps are updated:

• Countries (updated to 1995 boundaries)
  
• World Organization memberships (updated to 1995)
  
• Cities (now has 2,500 cities, with 1994 estimated population figures, compared to ArcWorld 1:3M cities)
  
• Latitude Longitude coverage (improved by using route subclasses and adding named latitude-longitude lines)

The following maps are new:

• First-level administrative areas for 150 countries (i.e., states, provinces, and their equivalents)
  
• Ports attribute table (can be joined to the cities map)
  
• Universal Transverse Mercator Zone Index
  
• Bailey Equal-Area Grid (for comparing areas of equal size, especially on maps that are drawn in non-equal-area projections)
  
• Population and Population Density grids (developed by the Global Geography Project)

The ArcWorld supplement dataset is available through our AFS directory.

It is also available on CD-ROM and may be borrowed from Branner Library. It is packaged together with the ArcWorld CD-ROM. Both CDs must be checked out together:
