资源简介：
The digital geologic map and GIS database of Venezuela captures GIS compatible
geologic and hydrologic data from the "Geologic Shaded Relief Map of
Venezuela," which was released online as U.S. Geological Survey Open-File
Report 2005-1038. Digital datasets and corresponding metadata files are stored
in ESRI geodatabase format; accessible via ArcGIS 9.X. Feature classes in the
geodatabase include geologic unit polygons, open water polygons, coincident
geologic unit linework (contacts, faults, etc.) and non-coincident geologic
unit linework (folds, drainage networks, etc.). Geologic unit polygon data were
attributed for age, name, and lithologic type following the Léxico
Estratigráfico de Venezuela. All digital datasets were captured from source
data at 1:750,000. Although users may view and analyze data at varying scales,
the authors make no guarantee as to the accuracy of the data at scales larger
than 1:750,000.
