Edge of Pavement 2014 - Polygon
vector digital data
These data were collected from aerial imagery flown spring 2014. Stereo compilation for planinmetric building outline data occured between 7/8/2015 through 11/3/2015. DRCOG Denver Region Urbanized Project Area
This metadata describes the stereocompiled Edge of Pavement (EOP) polygons feature of DRCOG Denver Region Urbanized Project Area. The feature was compiled from the Denver Regional Aerial Photography Project (DRAPP) 2014 Aerial Imagery Acquisition and Production. This 1"=100' scale imagery is comprised of 4-band RGBIR color orthoimagery with a GSD (Ground Sample Distance) of 0.5'. Imagery was collected with the Leica ADS40 and ADS80 digital sensors and processed with Leica XPro software. Imagery is projected in State Plane Coordinate System, Colorado central zone using the Lambert Conformal Conic map projection parameters. Horizontal and vertical datums are NAD83(11) and NAVD88(GEOID12A) respectively.
Outline of paved and unpaved streets/roads with width >= 9ft. Unpaved trail is not included in this layer.
Capture criteria: Outline of paved and unpaved streets/roads, and paved trails with width >= 5ft. Unpaved trail is not included in this layer.
Edge should be the flowline (lowest point in curb). A road/street/trail is defined as having consistent material from edge to edge. Includes paved and unpaved features intended for street-legal vehicle use (corridors) and paved features intended for recreational purposes (trails). Public paved trails are included but not private. Breaks should occur at intersections and where surface type or type changes (see attribution below). Median are delineated by a curb or raised surface (see blue outline in screenshot), not a paint line. Paved road polygons take precendence over sidewalk polygons, but unpaved roads do not (see green box in screenshot). Whenever it is ambiguous in identifying a path as either a public sidewalk or trail, or if has dual purpose, collect the path as trail, provided that the collection does not conflict with other capture criteria.
Extraction Guidance: Digitize from aerial imagery (2D).

Compliance with the collection and accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of aerial imagery. A softcopy aerotriangulation adjustment is performed on the aerial imagery is Leica XPro software. Accuracy of the stereo compiled features is a function of the aerotriangulation accuracy as summarized by the X, Y, Z RMSE statistics of the ground control points.
Completeness is ensured in the final vector editing process by comparison to the 2014 digital orthoimages as a backdrop to the edge of pavement vector features.

Coordinates defining the features.
The type of paved or unpaved feature that is delineated.
"Corridor" or "median".
Type of surface
Text that explains anything a user needs to know to interpret how or why the feature was delineated, if not obvious according to the capture criteria.
Median is any section within a corridor that you can't drive on,. Medians can contain any ground cover (grass. Concrete, gravel, plantings, etc). Medians includes traffic islands. Islands in cul-de-sacs should be captured.
