  Description:
    Abstract:
      This digital database, which was compiled from unpublished data and new mapping, contains the geologic data used to produce the 1:100,000-scale Geologic Map of the Fredonia 30' x 60' Quadrangle, Mohave and Coconino Counties, Northern Arizona.  The Kaibab-Paiute tribal government requested that all geologic information within their Reservation boundary be eliminated from this map.  The geologic features that were mapped as part of this project include:  geologic contacts and faults, bedrock and surficial geologic units, structural data, fold axes, karst features, mines, and volcanic features.  The features were identified on 1:24,000-scale aerial photographs taken in 1976 and 2005, then compiled on 1:24,000-scale paper USGS topographic base maps.  The compilation maps were extensively field-checked, then scanned, georeferenced, and digitized.  The resultant feature classes preserve the 1:24,000-scale data (the scale of the source mapping), and also contain attributes that facilitate generalization to 1:100,000 (the scale used to produce the published geologic map which is more applicable for regional studies/analysis).

      Note:  This metadata report provides an overview of the data content of this geodatabase.  In addition, each feature class (except annotation feature classes) has a corresponding metadata report that should be referred to for additional Spatial Data Organization, Data Quality and Entity Attribute information.
    Purpose: This digital database was produced as part of a cooperative effort between the U.S. Geological Survey, National Park Service, U.S. Forest Service, Bureau of Land Management, and the Kaibab-Paiute Tribe to provide regional geologic information.  Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The geologic information will be useful for resource management studies by federal, state, and private agencies.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Geologic features were identified, mapped, digitized, and attributed by the principle investigator (George Billingsley) or coauthor Sue Priest.  The features were symbolized based on their attributes and plotted at 1:24,000-scale, then compared visually with the original source maps.
  Logical_Consistency_Report: This database has been reviewed and is considered to be error-free.  All features have attributes.  Each line segment has a length and directionality that is appropriate for the geologic feature it depicts.  No sliver polygons are present.
  Completeness_Report: This database is considered complete.  All geologic features depicted on the source maps were digitized and attributed.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Most of the geologic features in this database are considered to be accurately located and within +/- 5 meters of their actual location on the topographic base map.  This accuracy diminishes in areas where the topography is either flat or very steep, or where the geologic feature of interest is difficult to discern.  For example, contacts between surficial units are often difficult to discern and are considered to be approximately located despite being attributed as accurately located.  The 1:24,000 topographic maps and corresponding Digital Raster Graphics (DRGs) that were used as the primary mapping base for this project were assumed to meet the National Map Accuracy Standard of +/- 12 meters.  The scanned source maps, which were georeferenced to the DRGs, all had registration errors of less than +/- 12 meters and most had errors of less than +/- 5 meters. (Note:  Refer to metadata reports for each feature class for more detailed information on positional accuracy of features).
  Lineage:
    Process_Step:
      Process_Description: Geologic features (outlined in Supplemental Information) were identified on 1:24,000-scale aerial photographs taken in 1976 and 2005. The features were compiled on 1:24,000-scale paper USGS topographic base maps.  These compilation maps were field-checked, then scanned on an HP800 scanner/copier at 300 dpi and saved in .TIF format.  The .TIF files were georeferenced in ArcMap to the corresponding 1:24,000-scale DRG, using a 1st-order polynomial transformation.  Geologic features were then heads-up digitized in ArcMap using the scanned compilation maps and the DRGs as a guide; digitizing scale was approximately 1:6,000.  The ArcCatalog process 'Create new polygon feature class from lines and points' was used to create geologic unit polygons (fredglg_poly_24k) from geologic contacts and faults (fredglg_arc) and geologic unit labels (fredglg_pt).  Each feature class was symbolized based on attributes and plotted at 1:24,000-scale and compared to the source maps.   Additional attributes were added to some feature classes to facilitate generalization of the features for use at 1:100,000-scale.
