Abstract or Description
The Bedrock Geology of Maine map was created using data layers from the Maine Office of GIS, Geo Data Explorer, a United States Geological Survey interactive map, and a hillshade of the state. Data were processed using ArcGIS 9 and show the relationship of bedrock to fault direction and elevation.
Source Data Note
Bedrock and county data were obtained from the Maine Office of GIS at a 1:500,000 scale. Bedrock data were reclassified to reflect age of rocks. Fault data were obtained from GEODE, a USGS interactive map at a 1:5,000,000 scale. The fault layer was reprojected using NAD 83 UTM Zone 19 N and clipped to overlay bedrock and county data.
