资源简介：
This is a coverage of the county boundaries of the conterminous United
States (AK, HI and Puerto Rico are available separately). The lines were
extracted from U.S. Census TIGER/line files using an AML program (see 4.),
written by Doug Nebert and Mark Negri, running on two Data General 6220
servers.
