- Abstract:
- Steams and lakes selected from 1:100,000 scale US Census
Bureau TIGER files. Selected to approximately match data
shown in USGS 1:2,000,000 scale DLG files. Names are mostly
from TIGER, also from Montana DOT county maps and USGS
quads. Not all polygons are water bodies. Select class > 0
before shading polygons. Select label eq "N" before labeling
small scale maps, or use "routetext hydro name name" rather
than "arctext" to label streams.
- Purpose: Base map data.

Data Quality Information:
- Attribute accuracy report:
- Accuracy of length and area attributes is unknown. Size
classification is arbitrary. In some cases, one fork
of a stream is used to represent the upper reaches of a
stream, so the name may not be exactly accurate.
- Logical consistency report: Polygon and arc/node topology exist.
- Completeness report:
- This is an arbitrary selection of streams from the TIGER
data. All known rivers were selected. Lakes and other
streams were selected based on area or length, spacing,
and familiarity.
- Horizontal Posistional Accuracy Report:
- Approximately 50 meters, assuming the source maps meet
National Map Accuracy Standards

- Title: 1990 TIGER/Line Files
- Edition: Census
- Publication place: Washington, DC
- Publisher: U.S. Census Bureau
- Source scale denominator: 100000
- Type of source media: unknown
- Source contribution:
- The lines in the coverage were selected from this data set.
This data set provided most of the stream and lake names.
- Calendar date: 01/01/1990
- Process step:
- Convert TIGER files to Arc/Info format and project them from
Geographic coordinates to Albers. Performed at the Billings
office of GeoResearch (406-248-6771).

- Process date: 10/12/1991
- Process step:
- Select major streams and lakes from the TIGER data.
This was performed between 10/1/92 and 7/23/93.
