Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota DNR - MIS Bureau
Abstract 1:24,000 scale streams captured from USGS seven and one-half minute quadrangle maps, with perennial vs. intermittent classification, and connectivity through lakes, rivers, and small wetland basins. Streams are also coded for their status as designated trout streams. Data originated with the MnDOT basemap stream traces. The data are fully integrated with the DNR 24K Lakes layer in the sense that overland streams terminate at lake and river shorelines.
Use Tips Data exhibit significant positional off-sets associated with complex meandered streams. Overall digitizing quality is highly variable. This data set, with its connectivity through water bodies, is designed to serve as the basis for hydrologic modelling efforts. It will also serve as the basis for a statewide stream referencing system. Strm_type codes greater than 32 are types of artificial connectors, and may be best dropped when creating cartographic products. Trout_flag values > 0 indicate designated trout streams (trout_flag=1) or protected tributaries to designated trout streams(trout_flag=2) as identified in Minnesota Rules Chapter 6264. See http://www.revisor.leg.state.mn.us/arule/6264/0050.html for legal descriptions and related restrictions. See also Minnesota Trout Streams layer (strm_troutln3) and PLS Sections with Designated Trout Streams layer (pls_troutpy3) for easier visualization of designated trout streams and tributaries. Users of trout stream information should be aware that the trout_flag code does not fully describe the extent of protected watercourses with regard to trout habitat or other state restrictions.

Purpose A 1:24K hydrography basemap to serve as the development of a statewide connected stream-trace network. Identification and coding of officially desiginated trout streams in Minnesota. To serve as the basis for a master stream-reach identification scheme.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy
Logical Consistency Data are topolocially correct using ARC/INFO 7.0.3. All lines intersect where intended. Some feature representation inconsistencies appear in the southeastern portion of the state, where river representation varies from a perennial stream classification (strm_type = 20) to river centerline (strm_type = 62), sometimes along USGS 7 1/2 minute quadrangle boundaries.
Completeness Data are complete when compared to stream traces presented on USGS 7 1/2 minute Quadrangle maps. Coding of designated trout streams and tributaries has been completed statewide; however, future revisions of trout designations are possible. Some streams have been coded with a Kittle Number (DNR Fisheries Stream ID#) and Kittname (DNR Fisheries common stream name); however, coding is in progress (April 2004) and incomplete statewide.
Horizontal Positional Accuracy Source layer dnrstln3: Horizontal positional accuracy is highly variable. Rectilinear features are probably accurate to 55 feet (based on estimated production errors and a mean sum square estimation). Feature representation of sinuous streams is especially variable, with accuracies in the 55 foot range present in some areas, and non-systematic offsets (especially as coarse generalizations) present in other areas of up to 150 feet. Quality typically varies along 7 1/2 quandrangle borders, with the most significant and consistent offsets observed in the northeastern portion of the state, and the best representations found in Southern Minnesota.
Vertical Positional Accuracy Source layer dnrstln3: Not Applicable
Lineage Attribute Lineage for source table STRM_BASELN3.DBF: In the initial DNR production effort, the data were plotted at scale and overlaid on paper versions of the USGS Quadrangle maps from which the data were originally derived. Attribute coding errors were identified and corrected in ARCEDIT. Center lines through hydrographic area features were also added and coded to reflect the type of feature being connected through. Next the data were joined and overlaid on a master lakes file. This step served as the basis for lake connector attribute coding. All data were brought into an ARCVIEW environment for coding of trout streams. DNR Fisheries staff, had previously manually highlighted designated trout streams on 7 1/2 minute quadrangles. These were used by DNR staff to flag streams with this special status. The data were previously overlaid with section lines to support this process, since the trout designations are referenced to and defined by section lines. In the Summer of 2001, a major restructuring of the data was implemented. This consisted of the following: resplitting the data into a major watershed-based library, addition of several columns to hold EPA river reach, Mankato State University-assigned stream and ditch names, and DNR Kittle numbers. Most features do not hold this information. The additional columns were added to receive information associated with on-going, long-term, maintenance and development activity. A route subclass was also created to hold Kittle watercourses as complex (multi-part) line features.
