<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>All public walkways are captured. Sidewalks do not overlap other feature classes unless they are hidden under a bridge or overpass. Cement pads around public swimming pools are captured. Walkways in common areas of apartments, college campuses, and business parks are captured as sidewalks. Individual resident sidewalks are not captured. Sidewalk: Sidewalks either compiled photogrammetrically as polygons or derived from a combination of vectors including: curbs, buildings, walls, driveways, or other features. Any stair feature that is less than 5 stairs is coded as sidewalk to maintain continuity. Hidden Sidewalk: Sidewalks that are obscured by overpasses or tunnels. They are not fully visible in an aerial photograph, but the location can be interpreted based on the information visible on either side of the bridge. Stairs: Groups of 5 or more stairs outside of major buildings or monuments, as well as part of sidewalks. Individual stairs are not captured. If landings exist within stairs, they are captured as sidewalk, not stairs. Crosswalk: Marked crosswalks that are fully visible in an aerial photograph.</SPAN></P></DIV></DIV></DIV> |
