Location
The 56 th Ave Underpass site has a pedestrian pathway going underneath 56th Ave in Denver, CO. The project will involve collection of an airborne LiDAR dataset over and 56th Ave, and a Colorized SLAM dataset of the underpass area.
PROJECT LOCATION:
- The survey area is near the intersection of 56th Ave and Dallas Street in Denver, CO.
- 58th Ave is the northern border, Chester Way is the approximate western border, and Dallas St is the eastern border.
- The survey area will extend south of 56th Ave so that full coverage of the underpass is collected by the airborne survey.
- The Northfield Tennis Courts are included to be used for camera calibration
