SR 52 7 Mile Realignment

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.

SR 52 limits rev1.

Project Overview

D7 in-house Design SWAT Project, 7 miles
New corridor alignment for SR 52 extension

ACA Project Approach

Mobile LiDAR
Aerial LiDAR with Digital Imagery
Traditional Survey

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.
Speed of delivery – Fast Paced Project for FDOT in-house design
