Addition information is available in the text and read-me file (non-GIS format). Online_Linkage: https://doi.org/10.3133/sim3402 Description: Abstract: This geodatabase represents the Surficial Materials Map of Massachusetts at 1:24,000 scale. The surficial geologic map database defines the distribution of nonlithified earth materials at the land surface and differentiates surficial materials of Quaternary age on the basis of their lithologic characteristics, constructional geomorphic features, stratigraphic relationships, and age. This compilation of surficial geologic materials defines the areas of exposed bedrock and the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits at a 1:24,000-scale level of accuracy. Purpose: The purpose of this study is to provide fundamental geologic data for the evaluation of natural resources, hazards, and land information within the Commonwealth of Massachusetts. Supplemental_Information: This geodatabase superseeds previously released Open-File Reports: 2006-1260-A, 2006-1260-B, 2006-1260-C, 2006-1260-D, 2006-1260-E, 2006-1260-F, 2006-1260-G, and 2006-1260-I. Shapefiles from those regional compilations have been revised for this seamless statewide geodatabase. Spatial data are in Massachusetts State Plane coordinates: NAD 1983, Massachusetts Mainland FIPS 2001, Lambert Conformal Conic Projection, units = meters. Horizontal datum is GCS_North_American_1983. The map data were interpreted at 1:24,000 scale. The database nearly conforms to the GeMS (previously known as NCGMP09) standard (https://ngmdb.usgs.gov/Info/standards/GeMS/). The native data structure is an ESRI ArcGIS 10.5 file geodatabase (.gdb) with ancillary files. The geodatabase contains the following elements: - DataSources (non-spatial table) - DescriptionOfMapUnits (non-spatial table) - GeoMaterialDict (non-spatial table) - Glossary (non-spatial table) - GeologicMap (feature dataset): descriptions of all features plotted on the geologic map, excluding base-map features. Contains feature classes: - DataSourcePolys - MapUnitOverlayPolys - MapUnitPolys - OverlayPolys Additional metadata records associated with each of these elements contain more detailed descriptions of their purpose, entities, and attributes. Non-spatial tables DataSources, DescriptionOfMapUnits, and Glossary store metadata. All spatial features and some non-spatial features have related entries in table DataSources. DescriptionOfMapUnits defines and describes geologic map units that are delimited in the feature classes MapUnitPolys, MapUnitOverlayPolys, and OverlayPolys. Most technical terms used as feature attributes (including all TYPE terms and all CONFIDENCE terms) are defined in table Glossary. Most features have explicit internal feature-level metadata, including one or more Source attributes, and, as appropriate, ExistenceConfidence and IdentityConfidence. Two shapefile versions of the dataset are also available. The OPEN shapefile version consists of shapefiles, DBF files, and pipe-delimited text files and retains all information in the native geodatabase, but has limited usability. The SIMPLE shapefile version consists only of shapefiles and is easily used, but lacks some information present in the native geodatabase. The metadata have not been edited to describe these other versions in detail.

This map product was prepared in cooperation with the Commonwealth of Massachusetts, Massachusetts Geological Survey and Executive Office for Administration and Finance. U.S. Geological Survey personnel compiled and digitized the geologic units to create the geodatabase. Native_Data_Set_Environment: Esri ArcGIS 10.5.0.6491 Data_Quality_Information: Logical_Consistency_Report: Polygon features conform to the following topological rules. There are no duplicate polygons. Polygons do not self overlap. Polygons may overlap other each other. Completeness_Report: The completeness of the data reflects the content and extent of the surficial geologic units of the compilation map. Additional information can be found on the data sources, which may be utilized in future revisions. The layer is complete in the sense that it accurately reflects the surficial geologic materials units for the state of Massachusetts noting that minor edits may occur to this dataset if it is re-released in future versions. This database superseeds Open-File Report series 2006-1260. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy of these data complies with the United States National Map Accuracy Standards for 1:24,000-scale maps. According to this standard, not more than 10 percent of the locations tested are to be in error by more than 1/50 inch (12.2 meters) measured on a publication scale of a USGS 7.5-minute topographic quadrangle map.

Process_Step: Process_Description: Paper copies of the previously published surficial geologic maps (see complete list in text references, or by quadrangle in Appendix 1 or DataSources table, or spatially in the DataSourcePolys feature layer) and were scanned at 500 dpi and georeferenced using lat/long coordinates (2nd-order polynomial transformation). Images were projected to UTM, zone 19, NAD27.

Digital geologic map units were compiled and grouped into basic units and attributed: artificial fill, swamp deposits, floodplain alluvial deposits, stream-terrace deposits, glacial stratified deposits, glacial till, and bedrock (outcrops and areas of shallow bedrock).

For unpublished quadrangles field maps were scanned and georeferenced (see complete list in text references, or by quadrangle in Appendix 1 or DataSources table, or spatially in the DataSourcePolys feature layer). Geologic units were vectorized or created (on screen digiziting) and basic units for each layer in each quad were edited, edge-matched with polygons in published quadangles, and appended into a single layer for each geologic unit.
