- Data Quality Information
- Logical Consistency Report
- No duplicate features are present. The shapefile is exported using Avenue request ExportClean. This request verifies and enforces the correctness of shapes.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set was extracted from the 1990 Census Version TIGER/Line(tm) files (CD-ROM edition). The positional accuracy of the TIGER/Line coordinates varies with the source materials used but at best meets the established National Map Accuracy standards (+/- 167 feet approximately) where 1:100,000-scale maps from the USGS are the source. The Census Bureau cannot specify the accuracy of feature updates added by its field staff or of features derived from the GBF/DIME-Files or other map sources. Thus, the level of positional accuracy in the TIGER/Line files is not suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface.

- Entity Type Definition
- The polygons represent U.S. Census block groups within Maine. A block group is a combination of census blocks that is a subdivision of a census tract or block numbering area. A block group consists of all blocks whose numbers begin with the same digit in a given census tract or block numbering area. The block group is the lowest level of geography for which the Census Bureau has tabulated sample data in the 1990 census.
