KML Files for "Geological Map of Garrett, Allegany and western Washington Counties in Maryland", Maryland Geological Survey

This file set contains keyhole markup language (KML) files derived from the GIS data set Geological Map of Garrett, Allegany and western Washington Counties in Maryland", by David K. Brezinski and Robert D. Conkwright, Jr (2013).  Three files are included in this initial release:

1 - WesternMDBedrockGeology.kml
2 - WesternMDSurfaceGeology.kml 
3 - WesternMDFaults.kml 

GIS data were compiled at a scale of 1:100,000 in ArcGIS Desktop 9.3.1.  Using the KML data at smaller scales, i.e. 1:60,000 or 1:24,000 will result in serious positional errors.  No warranty as to accuracy or content of these files is made.  This product is experimental and under development. 

KML files were produced using the ArcGIS extension:

   WesternMDSurfaceGeology.kml as the middle layer;
   WesternMDFaults.kml as the uppermost layer.
