Data Quality Information:
- Attribute accuracy report:
- School district numbers were copied directly from the 1992
TIGER files. Names were edited from the Census Bureau
look-up tables to eliminate all caps, notation that each
district is an elementary district, and to expand
abbreviations. The names have not been thouroughly
double-checked.
- Logical consistency report: Polygon and arc-node topology exists.
- Completeness report: Data set is complete
- Horizontal Posistional Accuracy Report:
- Approximate horizontal accuracy is 51 meters, assuming
source data meets National Map Accuracy Standards.
- Lineage:
- Source information:
- Originator: U.S. Census Bureau
- Publication date: 01/01/1992
- Title: 1992 Tiger/Line Files
- Edition: 1992
- Publication place: Washington, DC
- Publisher: U.S. Census Bureau
- Source scale denominator: 100000
- Type of source media: unknown
- Source contribution:
- The coordinates were copied from the TIGER files. The
TIGER attribute SDELM was used to determine which lines
were school district boundaries.
- Calendar date: 01/01/1992
- Process step:
- Convert TIGER files to Arc/Info format and project them
from geographic coordinates to Albers. See tiger92.aml
in /montana/census/tiger92.
-
- Process date: 05/01/1996
- Process step:
- Dissolve TIGER county coverages on the SDELM attribute.
Mapjoin all the coverages and dissolve again. Rename the
SDELM attribute DISTRICT.
-
- Process date: 05/02/1996
- Process step:
- Edit the Census district names in /montana/census/tiger92/
school.lut and save as /montana/census/tiger92/school.lut2.
Join the names in school.lut2 to the Polygon Attribute
Table.
