Abstract:
  This data contains road polygon 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 was received from 3Di West as 5 feature classes named Bridge_Deck, Paved_Edge, Unpaved_Edge, Private_Paved_Edge, and Private_Unpaved Edge. These have been combined into a single feature class with an attribute field called Type to distinguish between bridge decks, paved roads, and unpaved roads, and an attribute field called Private to identify the polygons from the "Private" feature classes. The "Private" features exist only in the Lake County portion of the data.

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.
