Supplemental Information

DNLNTYPE

Drainage line type

Code Definition

1. = Stream, river, channelized river

2. = Inland water body shoreline

3. = Wet sand limit

4. = Canal, aqueduct, flume, penstock, kanat, or similar feature (clearly

identified by ONC map annotation)

5. = Glacial limit

6. = Snowfield, glacier, or land ice water ice or ocean limit

7. = Ice free limit (land/ice line)

8. = Connector (used to separate inland water from open ocean or ocean

ice)*

9. = Tile boundary or null arc

*These lines were derived from the border between the shade for inland water

(dark blue) and open ocean or ocean ice (light blue) on the ONC sheets. The

cartographic judgements applied to the use of open ocean versus inland water

shading in near shore situations varies from sheet to sheet,

DLNSTAT

Drainage line status.

Code Definition

1. = Perennial (used for rivers and streams only)

2. = Nonperennial (used for rivers and streams only)

3. = Definite (used for inland shorelines only)

4. = Indefinite (used for inland shorelines only)

5. = Unsurveyed perennial

6. = Unsurveyed nonperennial

7. = Abandoned

8. = Under construction

9. = Suspended or elevated

10. = Underground

11. = Above ground

88. = Tile boundary

99. = None (no status attribute associated with feature)

Statement

Data origin:

http://data.geocomm.com/catalog/index.html

Positional accuracy of the drainage network was checked against google maps and a digital elevation model. Particularly in the upper streams positional accuracy is low, respectively does not fit to the contour lines in any case.
