Title:
Elements of infrastructure and seismic hazard in the central United States - Database
Abstract:
This digital map database consists of the ESRI ARC/INFO Version 7.0.2 coverages used to generate the plates in Professional Paper 1538-M (1994). Base-data is from 1:2,000,000-scale Digital Line Graph (DLG) data (roads, railroads, streams, water bodies, and international boundaries) and 1:100,000 scale DLG data (state and county boundaries).
