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

Outputs for highway teams

system(s)

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
