  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • G-polygon (3141)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1983.

  2. What changes have been made?

    Date: 20020204 (change 1 of 4) 
    The following steps were performed by ESRI for Data & Maps 2002:
Extracted 2000 Census tract geography from GDT Dynamap/Census Boundaries v4.0, and then aggregated it into counties (the boundaries, therefore, are consistent with the boundaries of the Census tracts and have all of the detailed vertices necessary to maintain consistency with the tract level of detail).  Added demographic attributes from Summary File 1 (SF1). Added farm attributes from 1997 Census of Agriculture.  Added Pop2001 attribute from ESRI Business Information Solutions.  Converted Hawaii to North American Datum of 1983 (NAD83) by splitting it from the rest of the United States; converting it to NAD83; then merging them together.  Recalculated any attributes based on area.  Created ArcGIS™ layer file (.lyr) and ArcView legend file (.avl).  Copied projection file (.prj), and created spatial indices.

    Data sources used in this process:
    • GDT Dynamap/Census Boundaries v4.0
    • Census SF1
    • ESRI BIS
    • USDA Farm

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

  2. How accurate are the geographic locations? 

    The geospatial part of this data set was extracted from the 2000 Census Version TIGER/Line™ files (CD–ROM edition).  The positional accuracy of the TIGER/Line coordinates varies with the source materials used but at best meets the established National Map Accuracy standards (+/- 167 feet approximately) where 1:100,000-scale maps from the USGS are the source. The Census Bureau cannot specify the accuracy of feature updates added by its field staff or of features derived from the GBF/DIME-Files or other map sources. Thus, the level of positional accuracy in the TIGER/Line files is not suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface.

  3. How accurate are the heights or depths?

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

    After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.  This file covers the extent only for the south central and eastern half of the US.  NBII-SAIN (ed.) created this file by clipping from from ESRI 2002 dtl_cnty.shp.  NBII-SAIN website:  (http://sain.nbii.gov/).

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

    No duplicate features are present.
