Description: This report presents the results of the USGS Mineral Resources Program activity to compile a national-scale geologic map database at a nominal scale of 1:500,000, to support national and regional level projects, including mineral resource and geoenvironmental assessments. The only comprehensive sources for input into regional- and national-scale geologic maps are state geologic maps with scales ranging from 1:100,000 to 1:1,000,000. Digital versions of these state maps form the core of what is presented here. These maps and databases are being released in blocks of states or, in the case of Alaska, as compiled blocks of 1:250,000-scale quadrangles as chapters in this series. 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.

Copyright Text: https://mrdata.usgs.gov/geology/state/state.php?state=NY. This layer was compiled by converting a kml file to a layer file.
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. 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. Bodies of water are classified as water, and the geologic units underlying them are not included in this coverage. The accuracy of the state boundary arcs is based on the 1:100,000 scale original data used to produce this boundary.
