Description: This dataset is a statewide polygon coverage of sand, gravel, and stone resources. This database includes the best data available from the VT Agency of Natural Resources and VTrans quadrangle maps where sand and gravel locations are noted. Sources are maps from "Geology for Environmental Planning" booklets prepared by Charles G. Doll in the 1970's, the data were derived from USGS sources. VCGI expects that this data will be updated and added to by other sources, but it is the most complete/accurate data available to us at this time.
Description: The GeologicBedrock_BDRK24K bedrock geology dataset includes several GIS data layers. The data was compiled from RF 24,000 USGS base maps. The data was created under the auspices of the Vermont Geological Survey with the assistance of the Information Management Section of the Agency of Natural Resources. The GeologicBedrock_BDRK24K dataset is organized into QUAD tiled (refer to VGIS Tile Structures information) "data bundles". Each data bundle includes several coverages; 1) CONTACTS (Lithographic contact layer), 2) DUCFLTCL (Faults, Anticlines Synclines), 3) FOLPT (trend and fold data), and 4) OUTCROP (exposed outcrops). Other coverages may be included with each data bundle. Refer to the README.TXT file included with each bundle.

Description: The GeologicSurficial_SURFICIAL data consists of surficial geologic features as digitized from the 1:62,500 15 minute series USGS quadrangle map sheets, compiled by The Vermont Geological Survey 1956-1970. Surficial geologic features are represented as polygon, line and point features.This layer is not symbolized. You can access fully symbolized layer files of point, polygon and line features relating to the surficial geologic features 1:62500 layer here:http://anrmaps.vermont.gov/websites/Geology/Surficial62kLayerFiles/

Description: A compilation of bedrock outcrops as points and/or polygons from 1:62,500 and 1:24,000 geologic mapping by the Vermont Geological Survey, the United States Geological Survey, and local colleges and universities between 1950-2016.Data was included as points or polygons based the source data.Includes data from VGS Open File Reports, VGS Bulletins, USGS reports, digitized 1:62,500 surficial and bedrock maps, student MS and PhD theses, and some unpublished data.For each point or polygon the NAD 1983 UTM Zone 18N X and Y coordinates are included (for polygons it is the X and Y coordinates of the centroid).A reference and publication year are included when possible.Compiled in January, 2017.

Description: The updated VT's Biophyscial Region Map (Ferree 2008), with 9 regions, replaces the older 8 region version from the VT Biodiversity Project (1998). The new biophysical region is the Champlain Hills, a section split off from the northeastern part of the former (now smaller) Champlain Valley region. The biophysical regions are a key aspect of the Vermont Conservation Design that is displayed in BioFinder. The updated and improved map should be used for all land use and planning puposes.

Description: A compilation of landslide locations from the Vermont Geological Survey's preliminary landslide inventory and verified landslides from GeoForm survey. This compilation includes sites from existing county-wide landslide inventories, Vermont Geological Survey surficial geologic maps and publications, and sites from Vermont Agency of Natural Resources Stream Geomorphic Assessment. This dataset is a compilation of available data for active, inactive and relict (historic) sites and is not a complete inventory of Vermont landslides. The inventory includes historic documented sites and landslides verified by field visits or remote sensing. Points represent feature locations and are not indicative of feature extent. Definitions:Landslide: A feature formed by the downslope movement of rock and soil under the effects of gravity. The term includes a wide variety of falls, slides, and flows. They are identified by the presence of steep slopes and/or evidence of soil movement and surface erosion. Most are adjacent to streams. Features below 4 meters in height are not mapped. The mass failures identified during stream geomorphic assessment studiesare landslides.Gully: A steep, narrow stream channel incised into surficial deposits. The stream is commonly a first-order stream and the flow in the bottom is usually intermittent. Unstable gullies have very steep sides and commonly show signs of fresh erosion in the bed and/or at the gully heads.Gully head: The upstream tip of a gully. One gully may have several gully heads.Landslide-gully complex. A gully with substantial landslides on the sides or at the head.
