Digital geologic map and GIS database of Venezuela
Dataset Identification:
Resource Abstract:
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 Lexico Estratigrafico 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.
