Process step:

Convert TIGER files to Arc/Info format and dissolve polygons to form Census Blocks. Project data from geographic coordinates to Albers. Performed at the Billings office of GeoResearch (406-248-6771).


Process date: 10/12/1991

Process step:

Read Public Law 94-171 data and join to TIGER coverage as attributes. Performed at the Billings office of GeoResearch (406-248-6771).


Process date: 10/12/1991

Process step:

Shift GeoResearch data 55.9 meters East and 2.4 meters North. We do not know how this error was introduced. The data now matches up with USGS 100K DLG data and 1992 TIGER files.
