FDOT Case Study for Data Fusion in Design Surveys
Presented at the FDOT Design Expo in Jacksonville FL, May 2016
Delivering a complete topographic design file using data fusion of Aerial LiDAR, Mobile LiDAR, and Traditional Survey. Topics include integrating control for different collection methods, merging LiDAR data sets for comprehensive project coverage, merging the different survey files into a corridor modeling Microstation SS4 deliverables.
D7 in-house Design SWAT Project, 7 miles
New corridor alignment for SR 52 extension
ACA Project Approach
Aerial LiDAR with Digital Imagery
Why Hybrid Technical Approach?
Full coverage of project area (expanded project width for alignment analysis)
Mobile LiDAR added high accuracy on the roads
Aerial Imagery required for analysis and public involvement
Aerial LiDAR provided better penetration within tree areas to limit obscured locations.
