Introduction This dataset was created to serve as a base-map for coal samples collected by Instituto Nacional de Geología y Minería INGEOMIN (INGEOMIN) of Venezuela and submitted to the U.S. Geological Survey's World Coal Quality Inventory project.

Garrity U.S. Geological Survey National Center 12201 Sunrise Valley Drive Reston, VA 20192 Telephone: 703-648-6426 Email: cgarrity@usgs.gov 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, and so forth) and non-coincident geologic unit linework (folds, drainage networks, and so forth). 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 a scale of 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. System Requirements ArcGIS Desktop 9.X Windows XP /Windows 2000 CPU Speed: 1.0 GHz recommended or higher Processor: Intel Pentium or Intel Xeon Processors Memory/RAM: 512 MB minimum, 1 GB recommended or higher Display Color: Greater than 256 color depth Swap Space: 300 MB minimum Disk Space: Typical 765 MB NTFS, Complete 1040 MB NTFS Data Disk Space Requirements: 70MB Geodatabase and associated files (Unzipped) Getting Started The digital geologic map and GIS database of Venezuela and associated files are bundled in a single downloadable zip file called USGS_06_DS_199.zip. To install: 1. Download USGS_06_DS_199.zip (~46MB space required) to local hard drive 2. Open with Winzip or other zip utility and click the “Extract” button (highlighting of the individual files is not necessary) 3. Extract contents to a destination on the local hard drive 4. A folder will be created called USGS_06_DS_199 5. Inside the folder click GMV.mxd to launch the map document Folder Contents When USGS_06_DS_199.zip is extracted, a folder by the same name is created. The contents of the folder are: 1. GMV.mxd – ArcGIS map document that launches the program 2. GMV.mdb- ArcGIS geodatabase containing comprehensive spatial data 3. GMV.mxd.xml – Bundled metadata files viewable and exportable through ArcCatalog (recommended) or XML editor 4. “Layers” folder containing ArcGIS symbology files for selected feature classes in the geodatabase Metadata Each feature class has associated metadata that is viewable and exportable through ArcCatalog. To view the metadata file, simply click on the feature class in ArcCatalog and then click the Metadata tab.
