Continental Mapping was engaged by the Indiana Department of Transportation (INDOT) to complete a mobile lidar and aerial mapping project of the South Split intersection in Indianapolis, Indiana. Within a week's notice, Continental Mapping mobilized its mobile lidar system and plane to collect over 15 lane miles of highway and 30 bridges to support design modifications after a bridge collision. Continental Mapping fused the mobile lidar and aerial imagery to deliver high accuracy 3D data, including 1" planimetric mapping, 1' contours, and a calibrated point cloud within 0.1' vertical accuracy to expedite the design and reconstruction process.

- 1. CONTINENTAL MAPPING Mapping from Earth, Sky and Space www.continentalmapping.com Madison, Wisconsin Indianapolis, Indiana Kansas City, Kansas St. Louis, Missouri Since 1999 more than 400 collisions have been recorded at bridges throughout the South Split (intersection of I-65/I-70) in Indianapolis, Indiana. On February 22nd, 2013 a semi-trailer hauling elevator equip- ment collided with the Virginia Street Bridge overpass, causing a sup- port beam to split, and severely impacting traffic. INDOT responded swiftly engaging with Continental Mapping to complete a mobile lidar aerial and mapping project for the site. Time was of the essence to provide survey data to INDOT’s engineers for design modifications. With under a week’s notice, Continental Mapping mobilized its VMX-250 Riegl mobile lidar system and plane to collect mobile lidar and aerial imagery. The mobile unit collected over 15 lane miles of highway including over 30 bridges. Continental Mapping fused the mobile lidar and imagery to complete 1”=25’ planimetric mapping throughout the corridor and deliver stereo bridge clearances, 1’ con- tours, DTM, orthos and a calibrated point cloud all to within 0.1’ verti- cal accuracy on hard surfaces. Indiana DOT Mobile Lidar & Photogrammetry LOCATION: Indianapolis, Indiana YEAR COMPLETED: 2013 OBJECTIVE: Deliver survey grade accurate 3-D data with speed and efficiency to expedite design & construction KEY POINTS: • Speed: Mobilization and acquisition completed within 10 days of initial phone call. • Data Fusion: Hybrid solution of mobile lidar and photogrammetry. • Engineering Ready Deliveries: DTM derived from fusion of mobile lidar and photogrammetry. Delivered in CAD formats. • Speed: Reconstructed South Split opens to traffic on 10/16/13, more than 2 weeks ahead of aggressive schedule. image source: INDOT image source: INDOT
