WhiteStar's
State and County Line Database
is a seamless, high-resolution database of state and county boundaries
rectified to 7.5 minute USGS topographic maps. All boundaries precisely
overlay the Public Land Survey and Texas Land Survey grids, USGS Digital
Orthophotos, and USGS Digital Raster Graphs.
Data Source
WhiteStar's State and County Boundaries are digitized from USGS
7.5 minute 1:24,000 scale topographic maps.

ESRI GIS technology, WhiteStar has created
clean polygonal

with attributes and map-friendly annotation. The resulting data provide
seamless coverage across states.

Code and state or county name.
