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

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.
