    arcs
    Characteristics of the arc features in featureclass noatak_geo_arc are coded in the attribute table, in items: ARC-CODE and LTYPE. (Source: This dataset)

    ARC-CODE
    ARC-CODE is a positive integer value (3 3 I) item in the arc attribute table. Values range nonsequentially from 0 to 105. ARC-CODE identifies a stratigraphic boundary, fault, or other linear feature. The ARC-CODE is described by the item LTYPE. (Source: This dataset)

    polygons
    Characteristics of the polygon features in featureclass noatak_geo_polygon are coded in items: CLASS, UNITTYPE (deposit type), UNITLABEL (geologic unit label), (Source: This dataset)

    CLASS
    CLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range nonsequentially from 1 to 1008. Every unit listed in the description of map units has a unique CLASS value. Units that are queried, shown in parentheses, or the overlying component of a compound unit are attributed with the same class value as the listed unit.
    Units queried where uncertain. Map units shown in parentheses indicate thin and generally discontinuous deposits above near-surface bedrock. Unit labels containing a slash indicate compound units where one unit is stratigraphically above another.
    Each CLASS value listed below is defined by the information from the UNITTYPE (100 100 c) item and the UNITLABEL (10 10 c) item which contains the geologic unit label if one was assigned. A different range of class values are assigned for each UNITYPE listed in the descriptions. (Source: This dataset)

    UNITLABEL
    UNITLABEL is a character (10 10 c) item in the polygon attribute table. Every polygon in the dataset is identified by a unique UNITLABEL. Units that are queried, shown in parentheses, or the overlying component of a compound unit are attributed with the same class value as the listed unit.
    Units queried where uncertain. Map units shown in parentheses indicate thin and generally discontinuous deposits above near-surface bedrock. Unit labels containing a slash indicate compound units where one unit is stratigraphically above another.
    Each UNITLABEL listed below is defined by the information from the UNITNAME (120 120 c) item which provides the name of the unit. (Source: This dataset)

    MODIFIER
    MODIFIER is a character (30 30 c) item in the polygon attribute table. MODIFIER describes additional surface characteristics of a unit if known. The same attribute can be assigned to multiple units. MODIFIER is also used to place an overprint pattern on the map. (Source: This dataset)

    points
    Characteristics of point features in featureclass noa_pnt_point are coded in item CODE and described in item DESCRIPTION. (Source: This dataset)

    CODE
    CODE is a positive integer value (3 3 I) item in the point attribute table. Every unique type of point has a unique CODE value. Each CODE value listed below is described and then defined by the information from the DESCRIPTION (80 80 c) item. (Source: This dataset)

    ValueDefinition

    arcs
    Characteristics of arc features in featureclass noatak_arrow_arc are coded in items: ARC-CODE and LTYPE. (Source: This dataset)

    ARC-CODE
    ARC-CODE is a positive integer value (3 3 I) item in the point attribute table. Every unique type of point has a unique ARC-CODE value. Each ARC-CODE value listed below is described and then defined by the information from the LTYPE (80 80 c) item. (Source: This dataset)

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

  2. Who also contributed to the data set?

    This digital coverage was created by Keith Labay, USGS, Nora Shew, USGS, Shaun Peterson, SAIC contractor, and Dan Grunwald, SAIC contractor.

  3. To whom should users address questions about the data?

Why was the data set created?

Digital representation of geologic mapping facilitates the presentation and analysis of earth-science data. Digital maps may be displayed at any scale or projection, however the geologic data in this coverage is not intended for use at a scale larger than 1:250,000.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 2006 (process 1 of 2)
    Linework was captured by scanning inked mylar overlays or paper maps to create TIFF files that were then "heads-up" digitized on screen. After vectorization, the linework was imported to Arc/Info coverages, and attribute values set for the data in ARC/INFO workstation. The digital data has been visually checked and the geologic map has undergone technical review. Vector data was then imported to an ESRI Geodatabase using ArcGIS 9.3.1, and the map was symbolized in ArcMap.

  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?

    Linework was captured by scanning inked mylar overlays or paper maps to create TIFF files that were then "heads-up" digitized on screen. After vectorization, the linework was imported to Arc/Info coverages, and attribute values set for the data in ARC/INFO workstation. The digital data has been visually checked and the geologic map has undergone technical review.

  2. How accurate are the geographic locations?

    Users of this digital geologic map should respect the intentions of the original mappers and the limitations of the map. This geologic map compilation is intended to be used at a scale of 1:250,000; it is not intended to be used at a more detailed scale.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    These ArcGIS featureclasses were used to create the map portion of SIM 3036. Text files, tables, graphics, and symbolsets shown on the map sheet are not included.

  5. How consistent are the relationships among the observations, including topology?

    Featureclass noatak_geo_polygon contains polygons representing geologic map units or water bodies. Each polygon has a coded attribute designating the mapped geologic unit. There is an associated lookup data table, noa_poly4_lut, that is used to assign polygon fill colors to map unit areas. Some polygons are also filled with patterns.

    Featureclass noatak_geo_arc contains arcs representing stratigraphic contacts and water boundaries.
    Featureclass noatak_arrow_arc contains lines for directional arrows indicating directions of glacial movement.
    Featureclass neat_arc contains a neat line marking the edge of the mapped area.
    Featureclass noa_npb_arc contains a neat line marking the boundary of the Noatak National Preserve.
    Featureclass noa_qb_arc contains lines marking the boundaries of 1:250,000 scale quadrangles.
    Featureclass UID_Leaders contains leader lines for geologic map unit labels which could not be placed within the area of the map unit.

    Featureclass noatak_pnt_point contains points representing pingos, springs, and mountain passes.
    Featureclass noatak_town_point contains a point representing the one town in the mapped area.

    Featureclass noatak_geopolygonUIDAnno contains annotation text for geologic map unit Unit Labels.
    Featureclass PlaceLandAnno contains annotation text for geographic land features.
    Featureclass PlaceWaterAnno contains annotation text for geographic water features.
