Why was the data set created?

U.S. Urbanized Areas provides information about the locations, names, and urban codes of urbanized areas primarily for national planning applications.

How was the data set created?

  1. Where did the data come from?

    BTS - Urban (source 1 of 1)

    Bureau of Transportation Statistics, 1997, Bureau of the Census Urbanized Area Boundaries: Bureau of the Census Urbanized Area Boundaries 1997, Bureau of Transportation Statistics, Washington, DC, USA.

    This is part of the following larger work:

    Bureau of Transportation Statistics, 1997, National Transportation Atlas Databases: National Transportation Atlas Databases 1997, Bureau of Transportation Statistics, Washington, DC, USA.

    Type of source media: CD–ROM
    Source scale denominator: 100000
    Source contribution:
    Attribute and geospatial data

  2. What changes have been made?

    Date: 1997 (change 1 of 3)
    The Bureau of the Census Urbanized Area database was derived from the TIGER database and published in 1992.  It was created from data created at a scale of 1:100,000 or better.

    Data sources produced in this process:
    • BTS - Urban

    Date: 20000731 (change 2 of 3)
    The following steps were performed by ESRI: Extracted data set from the Bureau of the Census Urbanized Area Boundaries within the National Transportation Atlas Databases. Generalized the data (tolerance unknown). Converted to North American Datum of 1983 (NAD83). Created ArcGIS™ layer file (.lyr).  Created ArcView legend file (.avl).  Created projection file (.prj).  Ran ArcView Avenue request ExportClean, and created spatial indices.

    Data sources used in this process:
    • BTS - Urban

    (change 3 of 3)
    Metadata imported.

    Data sources used in this process:

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 derived from the TIGER database with a positional accuracy of +/- 80 meters, and then generalized (tolerance unknown).  Generalization reduced the positional accuracy and is unknown.

  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 shapefile covers only the south central and the eastern half of the US.  NBII-SAIN (ed.) created this file by clipping from from ESRI 2002 urban.shp.  NBII-SAIN website:  (http://sain.nbii.gov/).

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

    No duplicate features are present.  The shapefile is exported using Avenue request ExportClean.  This request verifies and enforces the correctness of shapes.
