Metadata Summary

Originator U.S. Census Bureau and the Metropolitan Council
Abstract This 'Redistricting' version of the census data is the first release of the data.

This 2000 census redistricting geography database of the 7 county metropolitan area and the additional 12 collar county area was developed from the U.S. Census Bureau's Redistricting Census 2000 TIGER/Line files.

The Metropolitan Council downloaded this data from the Census Bureau's FTP site, imported it into ArcInfo coverage format, added a few items to the coverage, then created block, block group, tract, county subdivision (city), county, taz and water coverages and shape files from the original data.

Ordering Instructions This dataset is distributed on the internet.

By clicking below after 'Online Linkage' you will be able to download the 7-county metro shape files.

To download the shape files for the collar counties, click on this link: ftp://gisftp.metc.state.mn.us/census_2000_tiger_collar.zip

Doing so will tell your browser to download a 'ZIP' file which will contain the following:

- ArcView shape files
- metadata for the dataset (.htm)
- NOTICE.RTF, an important notice about this dataset that can be read by any word processing software.

This dataset can also be viewed and downloaded from the MetroGIS DataFinder Cafe at http://www.datafinder.org/cafe/ . The Cafe allows users to subset or clip datasets using an existing feature, such as a city or school district boundary or an ad-hoc, user defined area.

Additionally, this dataset is available for direct use via one or more map services. More information about what a web mapping service is can be found at http://www.datafinder.org/services/ . The specific map service and layer name for this dataset can be found by clicking the blue or green boxes under the map service column of the DataFinder Catalog at http://www.datafinder.org/catalog/ .

Extracted each zipped file to individual county directories, for example, to .../.../census/tiger00/anok

Renamed all the Tgr27019.rt1 (etc.) files with lowercase letters (to tgr27019.rt1), 17 files per county in Windows explorer (required for Unix ArcInfo 8.1 to recognize TIGER files).

Added items to the TIGER base coverage
dissovled 7 coverages from the base coverage: Block, Block Group, Tract, Cousub, County, TAZ, and Water.

Added and standardized items, then, for each layer, map joined all 7 counties and the remaining 12 counties.

Created shape files from these 14 coverages.
