A primary goal of this work is to develop geologic map datasets with standardized structure and attribution. The database design and standards are documented in CONUS documentation of this series. The intent is that contiguous databases can be merged seamlessly and without any additional effort. In addition to a common database structure, the conterminous U.S. state databases (the contiguous 48 states) have been fitted to a set of standard state boundaries derived from the USGS Digital Line Graph 1:100,000 quadrangle boundaries (Johnson and Leveritch, 1998) so that, when states are merged, they match without slivers or overlap. No attempt has been made to reconcile differences in mapping across state boundaries.

Johnson, Bruce R., unpublished, 1:100,000 Scale State Boundaries of the Conterminous United States.
Johnson, Bruce R., unpublished, Geologic Map Unit Classification, ver. 6.1.
The values of the attributes ROCKTYPE1 and ROCKTYPE2 were assigned based on the information in the legends of the source maps (most of which are paper). The definitions of these values are described in the draft document Geologic Map Classification version 6.1 (Johnson and others); available at the following website: <http://www.nadm-geo.org/dmdt/index.html>
Accuracy of New York state boundary and those arcs intersecting it: The accuracy of the state boundary arcs is based on the 1:100,000 scale original data used to produce this boundary. (Johnson, Bruce R. and Leveritch, Beth, 1998, 1:100,000 Scale State Boundaries of the Conterminous United States: U.S. Geological Survey, unpublished).
Those internal arcs intersecting the state boundary were extended or shortened as needed to complete polygons, possibly creating a small amount of error.
Bodies of water are classified as water, and the geologic units underlying them are not included in this coverage.
All internal polygons were checked for closure with vendor software and on hard copy plots. Overshoots and undershoots have been deleted or corrected as appropriate.
