United States federal agencies now make most of their information and data available via the Web. Many of their paper products are being discontinued and published instead on the Web. Cartographic materials available from foreign and U.S. state and local agencies are still limited but growing rapidly. The major sources for cartographic and digital spatial data information and some specific sites of important mapping data are listed.
