Description
Abstract: The Bureau of the Census Urbanized Area
Boundaries data set contains boundary information for
urban areas with a population greater than 50,000.
The data set includes boundaries for urban areas in
all 50 states, the District of Columbia, and Puerto Rico.
Purpose: The data provide users with information about
the locations, names, urban, census and FIPS Codes,
and size of urban areas primarily for national
planning applications.

DATA QUALITY INFORMATION
Attribute Accuracy
Attribute Accuracy Report: Attributes were supplied by
the Bureau of the Census.
Logical Consistency Report: All node-link and polygon
topological relationships are created and verified
using ARC/INFO.
Completeness Report: 405 distinct Urbanized areas are
identified in this data set.
Positional Accuracy
Horizontal Positional Accuracy
Horizontal Positional Accuracy Report: The Bureau of the
Census Urbanized Area database was derived from the
TIGER data base. It was created from data created
at a scale of 1:100,000 or better and as such has
a positional accuracy of +/- 80m.

Format Name: The BTS standard format
for spatial data is an interim format for
distributing National Transportation Atlas
Databases pending final approval of an SDTS
Transportation Network Profile (TNP). The BTS
standard format consists of a linked set of ASCII
fixed record length files. File formats and data
dictionary for the BTS standard format are
described in the document, National
Transportation Atlas Data Dictionary and Database
Formats', September 1995. Copies of this
documentation are distributed with each National
Transportation Atlas Database.
File Decompression Technique: No compression applied.
However, if using digital transfer online option,
note access instructions.
