Driveways (2020)

Last updated 3/18/2022

Driveway polygons delineated from 2020 aerial imagery. CAPTURE CRITERIA: Driveway polygons are compiled in 2D. This feature includes paved public and private polygon driveways. For sidewalk polygons meeting driveway aprons, the sidewalk supersedes. CHANGE FEATURES: This dataset is an update to previously collected data. Features were originally delineated from 2014 aerial imagery, updated in 2016, and then again in 2018 to create this dataset. Examples of change that are captured include but are not limited to: new features, change in attribution, and modifications that reach or exceed the threshold for initial collection of this feature. Additions refer not only to truly new features in the built environment but also to features that are added based on a larger extent of capture. Please refer to extent shapefiles for 2014, 2016 and 2018 feature captures before doing change analysis. Modifications are marked even if only a small portion of the feature has been changed. A separate change layer is available to show only those features that were delineated in 2020. SOURCE DATA: This feature was compiled from DRCOG 2020 Denver Regional Aerial Photography Project (DRAPP) imagery. This imagery is 4-band RGBIR color orthoimagery with a GSD (Ground Sample Distance) of 0.5 foot for 3-inch imagery, 1 foot for 6-inch imagery, and 2 feet for 12-inch imagery. Imagery was collected in the spring with a Vexcel Ultracam Eagle aerial sensor. Imagery is projected in the 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.
