Description:
Abstract:
This data set consists of the polygonal boundaries for the  Census 2000 Blocks
for Arizona.

Census Blocks are statistical areas bounded on all sides by visible features
such as streets, roads, streams and railroad tracks, and by invisible boundaries
such as city, town, township, and county limits and short imaginary extensions
of streets and roads. Generally census blocks are small in area, for example a
block in a city bounded by streets. However, census blocks in remote areas may
be large and irregular and contain hundreds of square miles.
Census blocks never cross county or census tract boundaries.
Purpose:
The data are created to serve as base information for use in GIS systems
for a variety of planning and analysis purposes.
These data do not represent a legal record.
Use of data for engineering work is prohibited.

Source_Contribution:


This source was used to create intermediate ARC/INFO
format data sets from which the data set was then
created.









Process_Step:








Process_Description:


The following ARC/INFO 8.1 commands were run to process the data downloaded from
www.esri.com/data/download/census2000_tigerline/index.html

Ran SHAPEARC on the Census 2000 TIGER/Line shape files to create ARC/INFO coverages.

Ran PROJECT to change the source projection
from Projection Geographic, units decimal degrees, Datum NAD83
to Projection UTM, zone 12, units meters, Datum NAD27.

Ran BUILD to update topology.
Ran JOINITEM to join the demographic attributes to the PAT.
Ran INDEX to increase selection speed.
