LandScope Engineering LtdSarah JonesGI Manager
Objectives
• To explore mobile mapping technologies for creating detailed 3D environments
• To demonstrate the tools and techniques used to deliver a comprehensive model serving numerous highway management functions
Overview
• Introduction• Mobile Mapping Technologies and Processes• Outputs for Highways Management– Topographical– Asset Inventory
• The Wider Context• Conclusions

Mobile Mapping - Acquisition
• Data Acquisition– high density point clouds (LiDAR)
One acquisition campaign feeds workflows for multiple outputs and deliverables
LiDAR Point Clouds
Mobile Mapping - Acquisition
• Data Acquisition– high density point clouds (LiDAR)– high resolution photography– high resolution video

Mobile Mapping - Processing
• Data Processing and Model Production– Point cloud and image integration– Orbit extraction – point, click and map– Visual interface• Identify• Measure• Map
Mobile Mapping - Accuracies• Positioning inputs include – GNSS– Inertial Motion Referencing – Odometers
• Various levels of accuracy available:– Post-processed GNSS / IMU– Trajectory Matched– Survey Control Point Matching

Advanced Integration
• API’s and SDK’s for integration– ArcGIS– AutoCAD 2014 – AutoCAD 2014
Joined up working
• Joined up working– Multi purpose (different departments)– Multi system rollout– Multi use • Highway Engineering • Asset Management These are just two
Web and Mobile deployment
• Transformation - GIS data to web / mobile GIS
• Mobile Mapping Publisher• Publisher SDK• Mobile Mapping Viewer• iOS Panoviewer
Visualisation
• Instant interpretation relating photographic data to reality
• Tool for remote working
Conclusions
• Mobile Mapping – multi discipline approach• Allows for better use of asset information• Provision of evidence based GI data • Improvements to service delivery e.g.
maintenance reporting, work schedules• Foundation for underpinning future highway
maintenance strategies
