Description

A characterization of the data, including its intended use and limitations.

Abstract: The Connecticut Quaternary Geology digital spatial data combines the information portrayed on the on-land portion of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin (Stone and others 2005) with the information portrayed on its sister map, the Surficial Materials Map of Connecticut (Stone and others, 1992). When used together, these maps provide a three dimensional context for understanding and predicting the internal composition, resource potential and hydrologic character of Connecticut's glacial and postglacial deposits. Both were compiled at 1:24,000 scale, and published at 1:125,000 scale.

The Quaternary Geologic Map of Connecticut and Long Island Sound Basin (Stone and others, 2005) portrays the glacial and postglacial deposits of Connecticut (including Long Island Sound) with an emphasis on where and how they were emplaced. Glacial Ice-Laid Deposits (thin till, thick till, and deposits of individual end moraines), Early Postglacial Deposits (Late Wisconsinan to Early Holocene stream terrace and inland dune deposits) and Holocene Postglacial Deposits (alluvium, swamp deposits, marsh deposits, beach and dune deposits, talus, and artificial fill) are differentiated from Glacial Meltwater Deposits. This mapping is based on the concept of systematic northward retreat of the Late Wisconsinan glacier. Meltwater deposits are divided into six depositional system categories (Deposits of Major Ice-Dammed Lakes, Deposits of Major Sediment-Dammed Lakes, Deposits of Related Series of Ice-Dammed Ponds, Deposits of Related Series of Sediment-Dammed Ponds, Deposits of Proximal Meltwater Streams, and Deposits of Distal Meltwater Streams) based on the arrangement and character of the groupings of sedimentary facies (morphosequences).

The Surficial Materials Map of Connecticut (Stone and others, 1992) portrays the glacial and postglacial deposits of Connecticut in terms of their aerial extent and subsurface textural relationships. Glacial Ice-Laid Deposits (thin till, thick till, end moraine deposits) and Postglacial Deposits (alluvium, swamp deposits, marsh deposits, beach deposits, talus, and artificial fill) are differentiated from Glacial Meltwater Deposits. The meltwater deposits are further characterized using four texturally-based map units (g = gravel, sg = sand and gravel, s = sand, and f = fines). In many places a single map unit (e.g. sand) is sufficient to describe the entire meltwater section. Where more complex stratigraphic relationships exist, "stacked" map units are used to characterize the subsurface (e.g. sg/s/f - sand and gravel overlying sand overlying fines). Where postglacial deposits overlie meltwater deposits, this relationship is also described (e.g. alluvium overlying sand). Map unit definitions (Surficial Materials Polygon Code definitions, found in the metadata) provide a short description of the inferred depositional environment for each of the glacial meltwater map units.

The geologic contacts between till and meltwater deposits coincide on both the Quaternary and Surficial Materials maps, as do the boundaries of polygons that define areas of thick till, alluvium, swamp deposits, marsh deposits, beach and dune deposits, talus, and artificial fill. Within the meltwater deposits, a Quaternary map unit (deposit) may contain several Surficial Materials textural units (akin to facies within a delta, for example). Combining the textural and vertical stacking information from the Surficial Materials map with the orderly portrayal of morphosequence relationships, up and down valley, that can be gleaned from the Quaternary map provides a three dimensional predictive context for relating the geologic setting of Connecticut's glacial meltwater deposits to their behavior as aquifers and/or transmitters of contaminants.

Since this data layer is a polygon and line feature representation of the two maps combined, each map unit's depiction and description could provide information as to its aerial extent, subsurface textural characteristics, depositional and paleogeographic settings, and facies composition in a morphosequence context. Therefore, a typical meltwater polygon would have a combination of Quaternary (e.g. Deposit of Major Sediment-Dammed Lake; Glacial Lake Middletown Cromwell Deltaic Deposit) and Surficial Materials (e.g. sand and gravel overlying sand overlying fine) map attributes. Additional polygon features are incorporated to define surface water areas for streams, lakes, ponds, bays, and estuaries greater than 5 acres in size. Line features describe the type of boundary between individual geologic or textural units such as a geologic contact line between two different geologic units or a linear shoreline feature between a textural unit and an adjacent waterbody.

The data have been updated to reflect minor changes in map unit name (QUPOLY_COD) for consistency with the 2005 publication of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin. Previously distributed versions of CTQSGEOM were consistent with the 1998 Open-file Report for the same map.

It is important to note that this data layer represents only the on-land portion of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin (Stone and others, 2005). The off-shore geologic units are organized in separate data layers (LISQMOR, LISQFAN, LISQLAKE, LISQCHAN, LISQMARD) which can be used in conjunction with this data layer. These Long Island Sound layers have been mapped at 1:80,000 scale using seismic reflection data.

The CTQSGEOM data layer should be used as the geologic base for Connecticut Quaternary Geology / Surficial Materials Features (CTQSFEAT) data layer which represents features such as eskers, meltwater channels, spillways, and locations of radio-carbon dated samples.

Purpose: Connecticut Quaternary Geology and Surficial Materials is 1:24,000-scale data suitable for geologic and environmental mapping and analysis purposes. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.). Not intended for analysis with other digital data compiled at scales greater than or more detailed than 1:24,000 scale. This data layer should be used as the geologic base for Connecticut Quaternary Geology / Surficial Materials Features (CTQSFEAT). The data layer can be used in conjunction with data layers representing related geologic features in the Long Island Sound Basin (LISQMOR, LISQFAN, LISQLAKE, LISQCHAN, LISQMARD).

Supplemental information: Data manually digitized from 1:24,000-scale mylar quadrangle compilation sheets prepared for the Surficial Materials Map of Connecticut, 1:125,000 scale (Stone and others, 1992) and the Quaternary Geologic Map Of Connecticut and Long Island Sound Basin, 1:125,000 scale (Stone and others,2005). For a more complete understanding of the geologic principles behind the data it is advisable to consult these source maps which contain cross sections, diagrams and text not available in digital form. Digital files which should be used with this data set include: SIM-2784.pdf (pamphet from the Quaternary Geologic Map Of Connecticut and Long Island Sound Basin), Surficial Materials data layer, and the companion data sets: Connecticut Quaternary Geology / Surficial Materials Features (CTQSFEAT), and Long Island Sound moraines (LISQMOR), lacustrine fans (LISQFAN), lake-bottom and deltaic deposits (LISQLAKE), channel-fill deposits (LISQCHAN), and marine deltaic deposits (LISQMARD); all available for download at http://www.dep.state.ct.us/gis.

Dataset credit: Kristi LeDuc, Margaret Thomas, and Mary DiGiacomo-Cohen for designing, compiling, digitizing, and editing the Quaternary Geology and Surficial Materials data layer. Much of the production effort was undertaken by the Long Island Sound Resource Center: a partnership between the State of Connecticut, Department of Environmental Protection and the University of Connecticut Marine Sciences and Technology Center. This digital data was produced by the State of Connecticut, Department of Environmental Protection with support from the U.S. Geological Survey, the U.S. Environmental Protection Agency, and the Connecticut Department of Public Health and Addiction Services. The U.S. Geological Survey in cooperation with the State of Connecticut, Department of Environmental Protection, Geological and Natural History Survey drafted the 1:24,000-scale compilation sheets used to publish the 1:125,000-scale Surficial Materials Map of Connecticut, Stone and others, 1992 and create the 1:24,000-scale digital data.

+ Data Quality and Accuracy Information

General

Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.

Logical consistency report: Polygon features conform to the following topological rules. Polygons are single part. There are no duplicate polygons. Polygons do not self overlap. Polygons do not overlap other polygons. Lines are single part. Line features conform to the following topological rules. There are no duplicate lines. Lines do not self overlap. Lines do not overlap other lines. Lines intersect only at nodes, and nodes anchor the ends of all lines. Lines do not overshoot or undershoot other lines they are supposed to meet and intersect. In general, there are no duplicate features, unresolved intersections, overshooting lines, open polygons, sliver polygons, or unlabeled (unattributed) polygons. The tests of logical consistency were performed by the State of Connecticut using ESRI ArcInfo software to maintain feature topology in ArcInfo coverage format. The data is topologically clean. The ArcInfo Clean function was repeatedly used following edits to verify topology and enforce a minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 0 feet (dangle length).

Completeness report: The data reflects the content of the data source, which is a set of 1:24,000 scale mylar sheets used to compile and publish the Surficial Material Map of Connecticut, Stone and others, 1992 (U.S. Geological Survey in cooperation with the Connecticut Geological and Natural History Survey, DEP, 2 sheets, 1:125,000 publication scale), and the Quaternary Geologic Map of Connecticut and Long Island Sound Basin, Stone and others, 2005 (U.S. Geological Survey in cooperation with the Connecticut Geological and Natural History Survey, DEP, 2 sheets, 1:125,000 publication scale). The datalayer was digitized from these 1:24,000-scale mylar compilation sheets. This datalayer (QUPOLY_COD - Quaternary Map unit label abbreviations) was updated to reflect minor editorial comments relating to the 2005 publication of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin. All 116 Connecticut quadrangles of mapped on-land Quaternary and surficial materials units have been digitized and included in this data layer; all off-shore Quaternary units have been digitized as a separate effort and are available as separate data layers (LISQMOR, LISQLAKE, LISQFAN, LISQCHAN, LISQMARD).

Attribute Accuracy

Accuracy of the identification of data entities, features and assignment of attribute values.

Attribute accuracy report: The Quaternary Geology/Surficial Materials layer retains the feature types and information identified on the 1:24,000-scale compilation sheets used for both the Surficial Materials Map of Connecticut, Stone and others, 1992 and the Quaternary Geologic Map of Connecticut and Long Island Sound Basin. All attributes have valid values. Values are within defined domains. The accuracy test for the SMPOLY_COD and QUPOLY_COD attribute values was conducted by comparing the geologic map unit information presented on the source mylar overlays with 1:24,000-scale check plots or interactive displays of the digital data on a computer graphic system. These check plot maps and computer displays depicted and labeled the polygon features in different colors and line-fill patterns based on SMPOLY_COD and QUPOLY_COD attribute values for comparison with the original data source. SURFM_POLY and SM_DESC represent both brief and full text English language equivalents of (decodes) the SMPOLY_COD attribute, respectively. The AV_LEGEND and IMS_LEGEND polygon attributes are based on and key off the QUPOLY_COD attribute. These related attributes were populated by joining to lookup data tables using the SMPOLY_COD as the relate key field instead of manually entering these values for each polygon feature. These lookup data tables contain records that account for and describe the unique occurrences of SMPOLY_COD values. The AREA_SQMI (area in square miles) and ACREAGE (area in acres) field were automatically calculated for each polygon feature based on computer generated feature area in square feet. For line features, the QSARC_COD attribute that distinguishes contact boundaries from shoreline boundaries was manually entered for each feature.

Positional Accuracy

Accuracy of the positional aspects of the data.

Horizontal accuracy report: The horizontal positional accuracy of this 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 (40 feet) measured on the publication scale of a USGS 7.5 minute topographic quadrangle map. Feature locations were interpolated from the transporation features, surface water features, elevation contours, buildings, built-up areas, and other natural features and landforms depicted on USGS 7.5 minute topographic quadrangle maps.

Conforms with Connecticut DEP Spatial Data Standards. Standards for feature accuracy are: 90 percent of the digitized features are within .01 inch of the centerline of that feature on the manuscript (original map); 100 percent of all features must be within .02 inch. There are no duplicate features, unresolved intersections, overshooting arcs, open polygons, sliver polygons, or unlabeled polygons. Fuzzy and Dangle Tolerances were verified and set in the ArcInfo coveage tolerance (TOL) file.

Process step information

Process Step 1

Process description: Feature digitizing (digitizing tablet method) - Using ESRI ArcInfo software, features were digitized by registering each source Mylar to the digitizing tablet and using the crosshairs of the digitizer's mouse to manually capture the geometry (location) of features drafted on the map. The corners of the USGS 7.5 minute topographic quadrangle maps are used as registration points and are depicted on the source map. Each source map was registered to the digitizing tablet by digitizing (entering) the locations of four quadrangle corner registration points shown on the map. ArcInfo software compared the values of the digitized coordinates with the actual (true) values for the quadrangle corner (tic) features. The Root Mean Square (RMS) error generated by the ArcInfo software indicated the amount of error involved in transforming coordinates from the registered map to the digital layer. RMS errors higher than 0.004 were not acceptable and required re-registering the source map by digitizing the tic locations again. Surficial material boundary lines (contacts) delineated on each source map were manually digitized according to the following spatial data accuracy standards: Standards for feature accuracy are: 90 percent of the digitized (linear) features are within .01 inch of their centerline on the original manuscript (source map); all digitize (linear) features are within .02 inch of their centerline on the original manuscript. Polygon features were created as a result of digitizing these (boundary) line features. The source maps are made from stable-base mylar.

Selected waterbodies greater than 5 acres and related shoreline features were incorporated from existing digital hydrography data. Digital compilation utilized hydrography from 7.5 minute, 1:24,000-scale U.S. Geological Survey Digital Line Graph source material (1969-1984) with minor modification of geologic contacts to fit the revised hydrography where necessary. Hydrography selected from the USGS Digital Line Graph data (code numbers 050 0412,050 0421, and 050 0116) include streams, lakes, ponds, bays, estuaries, and seas with areas greater than 5 acres.

In general, units shown on the 1:24,000-scale compilation sheets are typically those published on the 1:125,000-scale Surficial Materials Map of Connecticut. Additional map units may be present in the digital data that could not be readily shown on the published map at 1:125,000 scale or that represent more recent mapping, particularly along the coast. Some subsurface information as noted by stacked units may also be more detailed in the 1:24,000-scale digital data than that of the published 1:125,000-scale State Map.

Attribution - Each polygon feature was manually assigned the corresponding SMPOLY_COD attribute, indicating the geologic unit type based on information the compilation sheets. Additionally, line features were manually attributed with SMARC_COD values to distinguish geologic contacts from shoreline and the state boundary. Where necessary, additional minor corrections (edits) to feature geometry were manually digitized on the screen (heads-up digitizing) at display scales greater than 1:24,000. Feature location and attribute accuracy was visually checked and inspected by symbolizing and labeling features according to attribute value on the computer screen and on hard copy paper maps, and comparing this information to the original source data. These check plot maps were printed at the same scale as the source maps in order to visually inspect digitizing quality and the assignment of attribute values.

Edgematching - Features along the boundaries of adjacent 7.5-minute quadrangle coverages were made to match (connect) to each other through a process of checkerboard style edgematching. Following a checkerboard pattern, line features were only adjusted on every other quadrangle. The edgmatching process resulted in defining the same point coordinate where line features from two adjacent quadrangles connect along quadrangle boundaries. Essentially, line end points were snapped to connect to line end points of the corresponding stationary linear features on adjacent quadrangles. Edge matching was successfully completed once it was possible to append all 7.5-minute quadrangle coverages and assemble a statewide coverage with polygons that closed without gaps (slivers) and overlaps.

Appending - Subsequently, all 7.5-minute quadrangle coverages were appended to form a single, statewide Surficial Materials layer. Polygon features were merged across quadrangle boundaries. Linear features were unsplit (merged) to eliminate unnecessary pseudo nodes that connected similar line features (originally from different quadrangle coverages). Final polygon and line feature topology was established with ArcInfo Fuzzy and Dangle tolerances verified at 4 and 0 feet, respectively. Lookup tables were joined to the polygon and feature attribute to include additional attributes that decoded the SMPOLY_COD and SMARC_COD attributes such as SURFM_POLY, SURFM_ARC, DESC, and IMS_LEGEND. The AREA_SQMI (area in square miles) and ACREAGE (area in acres) field were automatically calculated for each polygon feature based on computer generated feature area in square feet. At this step in the process the Surficial Materials layer was fully attributed and ready for use.

Process Step 2

Process description: Quaternary units contacts manually digitized from 1:24,000 scale mylar compilation sheets using a Calcomp 9100 digitizing table, using the same standards decribed in Process step 1. These new Quaternary Geologic contacts were added to the existing digital Surficial Materials data layer and attibuted (QSARC_COD = 4). This was done because approximately 90% of the arcs defining the Quaternary Geology are the same as those defining the Surficial Materials polygons; although they were produced as separate USGS publications the maps were developed under a single philosophy and represent multiple attibutes of unified geologic model. All new vectors were edgematched, polygon topology was recreated. QSPOLY_COD was added and manually attributed. Line work and attibutes were checked by the on 1:24,000 scale plots and edited as necessary by the proceedure described in process step 1. Final polygon and line feature topology was established with ArcInfo Fuzzy and Dangle tolerances verified at 4 and 0 feet, respectively

Profile: ESRI Metadata Profile

Online linkage: http://www.esri.com/metadata/esriprof80.html

FGDC Plus Metadata Stylesheet

Stylesheet: FGDC Plus Stylesheet

File name: FGDC Plus.xsl

Version: 2.2

Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
