Online linkage: ftp://geoinfo.msl.mt.gov/Data/Spatial/NonMSDI/Collections/Flathead_2009/Vector_Data/Flathead_Breaklines.zip

Abstract:

This data contains hydrologically significant features photogrammetrically compiled for the Flathead Basin, Montana. The data were compiled from 1-foot resolution aerial photos taken between September 25 and September 28, 2009.

The data should be displayed and analyzed at scales appropriate for 1"= 200' (1:2400) map scale.

The data consists of 19 feature classes showing the locations of water bodies, paved and unpaved roads, dams, canals, intermittent and perennial streams, airport runways and taxiways, railroads, ditches, stream banks, and other features such as cliff tops, berms, and excavations.

Purpose:

These data were collected to represent breaklines to be used in creating a hydrologically-enforced Digital Elevation Model of the study area.

Data Quality Information:

Logical consistency report: All data was collected using similar methods and sources.

Completeness report:

Data collection limited to features visible and identifiable on 1:2400 (1" = 200') map scale aerial photography.

Horizontal Positional Accuracy Report:

0.98 feet horizontal accuracy using NSSDA method (95% confidence level).

Quantitative horizontal positional accuracy assessment:

Horizontal positional accuracy value: .98 feet
Horizontal positional accuracy explanation:: 13 check points of higher order accuracy were measured in the stereo imagery to yield NSSDA accuracy values.

Vertical positional accuracy report:

1.39 feet vertical accuracy using NSSDA method (95% confidence level).

Quantitative vertical positional accuracy assessment:

Vertical positional accuracy value: 1.39 feet
Vertical positional accuracy explanation:: 13 check points of higher order accuracy were measured in the stereo imagery to yield NSSDA accuracy values.
