Abstract:

This layer contains streams and lakes selected from 1:100,000 scale US Census Bureau TIGER files. The featues were selected to approximately match data shown in USGS 1:2,000,000 scale DLG files.

In these layers, lines may represent the centerline of a stream, the shorelines of a wide stream represented by a polygon, the shorelines of a lake, or a boundary between two polygons with different names. Polygons may represent lakes or wide streams. These layers are intended for cartographic representation of lakes and streams rather than geographic analyses.

Feature names are mostly from the TIGER files. Some were obtained from from Montana DOT county maps and USGS topographic maps.

Data Quality Information:

Attribute accuracy report:

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.

Completeness report:

This is an arbitrary selection of streams and lakes from the TIGER data. All known rivers were selected. Lakes and other streams were selected based on area or length, spacing, and familiarity.

Horizontal Positional Accuracy Report:

Approximately 50 meters, assuming the source maps meet National Map Accuracy Standards

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.


Process date: 07/23/1993

Process step:

Parrot Lake was incorrectly named Ester Lake. Corrected the name of Parrot Lake and added Ester Lake from TIGER data.
