Title:
Preliminary Integrated Geologic Map Databases for the United States: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, Rhode Island, Vermont
Abstract:
These metadata are specifically for the State of New Jersey, one state in the national compilation of state geologic map databases. The digital geologic state map data was prepared by the New Jersey Geological Survey in 1999. Subsequent editing of the spatial data by the USGS was limited to fitting a standardized state boundary to the data, standardizing the arc coding, reprojecting the data, and minor edits of arc or polygon attributes to conform with the paper map.

This open-file report is one of several that present the preliminary results of the USGS Mineral Resources Program activity to compile a national-scale geologic map database to support national and regional level projects, including mineral resource and geoenvironmental assessments. The only comprehensive sources of 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. Because no adequate geologic map exists for the state of Alaska, it is being compiled in regional blocks that also form part of this national database. It is expected that this series will completed by approximately the end of 2007. 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. For Alaska, formal maps as well as databases are being published here, whereas for the conterminous U.S. only state databases and preview graphics are presented, because published maps for most states already exist. For Alaska these regional compilations will form the base for compiling a new geologic map of the state. As documented in CONUSdocumentationNENJ.pdf, standards for the conterminous U.S. are somewhat different than those for Alaska and Hawaii.
Supplemental_Information:
This database consists of up to five major Arc/Info GIS datasets for each state; - one: geologic map with formations, - two: faults (where present), - three: dikes (where present), - four: miscellaneous line features (where present), - five: miscellaneous point features (where present).

Why was the data set created?

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 CONUSdocumentationNENJ.pdf 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 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.

How was the data set created?

  2. How were the data generated, processed, and modified?
    Date: 2003 (process 1 of 11)
    The purpose of this standardization is to allow all SGMC covers to be seamlessly joined without any additional effort to form regional or national level digital maps. Note that for Alaska, the state is being compiled as blocks of 1:250k quadrangles that will ultimately be used to compile a new state map. Douglas Stoeser (USGS) and Ric Wilson (USGS) are co-coordinators for the overall SGMC effort, with Stoeser coordinating work on the mainland states and Wilson coordinating work for Alaska and Hawaii.
    Date: 2006 (process 2 of 11)
    C.L. Dicken obtained the digital geologic map of New Jersey from CD series 00-1. The coverage was re-projected into the following:

    projection: Lambert Conformal Conic units: meters datum: NAD27 standard parallel 1: 33 0 0.000 standard parallel 2: 45 0 0.000 central meridian: -100 0 0.000 reference latitude: 0 0 0.000 false easting: 0.00000 false northing: 0.00000

    (Note: Attributes associated with the generation of the coverages were not deleted. PAT - shape, area, perimeter, coverage#, and coverage-id AAT - shape, fnode#, tnode#, lnode#, rnode#, length, coverage#, and coverage-id)

    All attributes were deleted except GEOABB. The values from GEOABB where then calculated into a new field called orig_label.
    Date: 2006 (process 3 of 11)
    The relevant state outline (arcs) was removed from the coverage and replaced with the arcs from the 1:100,000 Scale State Boundaries of the Conterminous United States.

    This allows for a seamless fit of each state to a standard state boundary base.
    Date: 2006 (process 4 of 11)
    The following attributes were exported from Filemaker as a .dbf: orig_label, map_symbol2, unit_link, reference_id, unit_age, rocktype1, and rocktype2.

    orig_label reflects the original map symbol used on the source map

    map_symbol2 reflects map-symbol1 with the addition of a province number

    unit_link is an auto generated field based on map-symbol2 and the state abbreviation (e.g. NJ001) that produces a unique identifier for each map unit

    reference_id was populated with an alphanumeric code (e.g. US001) that designates the source used for the linework and other references used to describe the age or lithologies of the unit.

    unit_age was populated with general age assignment

    rocktype1 records dominant lithology (does not imply minimum percentage of abundance), using standardized data dictionary

    rocktype2 records second most dominant lithology, using standardized data dictionary

    The attributes were then converted using the following structure:

    item name: orig_label width: 12 output: 12 type: c

    item name: sgmc_label width: 16 output: 16 type: c

    item name: unit_link width: 18 output: 18 type: c

    item name: source width: 6 output: 8 type: c

    item name: unit_age width: 60 output: 60 type: c

    item name: rocktype1 width: 40 output: 40 type: c

    item name: rocktype2 width: 40 output: 40 type: c
    Date: 2006 (process 5 of 11)
    Once the .dbf was in the correct format with standardized column widths and data structure, it was converted into a lookup table (.lut) in Arc/Info. Then a joinitem was performed to join the look-up table to the polygon attribute table. orig_label was used as the merge item.
    Date: 2006 (process 6 of 11)
    Next, in preparing the uniform .aat file, the following items were added to the table:

    item name: arc-code width: 3 output: 3 type: i

    item name: arc-para1 width: 3 output: 3 type: i

    item name: arc-para2 width: 3 output: 3 type: i

    item name: source width: 6 output: 8 type: c

    Date: 2006 (process 7 of 11)
    Arc-code was populated using the paper map source to tag the lines using the AAT line type data dictionary (see CONUSdocumentationNENJ.pdf in this series).

    Arc-para1 was populated when additional information was available such as identifying the upthrown side of a fault or direction of thrusting on a fault. (see CONUSdocumentationNENJ.pdf)

    Arc-para2 is a scratch field that is used mostly in Alaska.

    Source was populated with an alphanumeric code (e.g. US001) that designates the source used for the linework.

    Date: 2006 (process 8 of 11)
    Once the .aat and the .pat were populated with the correct attributes, the coverage was exported as an .e00 file (NJgeol_lcc.e00).

    Then it was unprojected into geographic coordinates and exported again (NJgeol_dd.e00).
    Date: 2006 (process 9 of 11)
    Faults were extracted from the coverage and created a separate fault coverage (NJfaults_lcc) and then exported (NJfaults_lcc.e00).
    Date: 2006 (process 10 of 11)
    Dikes were heads up digitized by C.L. Dicken and added as a separate coverage (NJdike_lcc) and then exported (NJdike_lcc.e00).
    Date: 2006 (process 11 of 11)
    Finally, the geology lines, geology polygons, faults and dikes were converted into shapefiles; in both geographic coordinates and in Lambert Conformal Conic projection.
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    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://geology.usgs.gov/dm
  2. How accurate are the geographic locations?
    Accuracy of New Jersey 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 (see metadata file: st100kmeta.txt, CONUSdocumentationNENJ.pdf))

    Those internal arcs intersecting the state boundary were extended or shortened as needed to complete polygons, possibly creating a small amount of error.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Bodies of water are classified as water, and the geologic units underlying them are not included in this coverage.
  5. How consistent are the relationships among the observations, including topology?
    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.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
