11. TYPICAL APPLICATIONS

12. APPLICATIONS – HIGHWAY MAINTENANCE
• EXISTING CONDITION SURVEY
• REPORTING OF EXISTING CONDITIONS
• OFTEN USED FOR ASSISTING WITH NEW DESIGNS
• AS-BUILT
• ENSURE THE DESIGNS ARE BEING CORRECTLY IMPLEMENTED ON SITE
• REPORT ANY DEVIATIONS TO THE CLIENT

13. APPLICATIONS – HIGHWAY MAINTENANCE

14. APPLICATIONS – BRIDGE HEIGHT MAPPING
• ACCURATE DATA ON VERTICAL CLEARANCES OF ROADWAY STRUCTURES IS CRITICALLY IMPORTANT IN OVERSIZE
ROUTE PLANNING
• TRADITIONALLY COLLECTING THIS DATA HAS THE FOLLOWING ISSUES:
• DANGEROUS AND CAN CAUSE CONGESTION WITH WORK CREWS SUBJECT TO SIGNIFICANT TRAFFIC HAZARDS
• WORK MUST BE PERFORMED DURING AVAILABLE TRAFFIC BREAKS
• MOBILE MAPPING SYSTEMS (MMS) COUPLED WITH AUTOMATED DATA EXTRACTION
• PROCESS UP TO 40 BRIDGES PER DAY
• SURVEY GRADE ACCURACY AT TRAFFIC SPEED

15. APPLICATIONS – BRIDGE HEIGHT MAPPING
5.24m 5.32m

16. APPLICATIONS – BRIDGE HEIGHT MAPPING
• TYPICAL REPORT GIVEN TO CLIENT

17. APPLICATIONS – MINING VOLUME MEASUREMENTS
• ACCURATELY MEASURING THE VOLUME AND MASS OF A STOCKPILE
• PRECISE MEASUREMENTS FOR FINANCIAL REPORTS AND EXCISE DUTY
• FOLLOWING REGULATORY REQUIREMENTS
• EU COUNTRIES MUST DO A MASS BALANCE TO CALCULATE CO2 EMISSION
• ASSISTING IN PLANNING
• TRADITIONAL TECHNIQUES SUCH AS GNSS AND TOTAL STATIONS CAN BE:
• TIME CONSUMING
• DANGEROUS (WALKING ON STOCKPILE)

18. APPLICATIONS – MINING VOLUME MEASUREMENTS

19. APPLICATIONS – SLOPE MONITORING
Mining Coastal Avalanche
Highways Railways Landslide

20. APPLICATIONS – SLOPE MONITORING
• LARGE LANDSLIDES USUALLY OCCUR AFTER A SMALL SLOPE FAILURE
• BASIC METHODOLOGY
• SCAN OBJECT
• RE-SCAN SAME OBJECT AT REGULAR INTERVALS
• DETECT ANY SMALL CHANGES
• SEND WARNING BEFORE MAJOR SLOPE FAILURE

21. APPLICATIONS – SLOPE MONITORING

22. APPLICATIONS – COASTAL SURVEYING
• APPLICATIONS INCLUDE:
• MONITORING OF CLIFFS FOR LANDSLIDES
• MEASURING EROSION
• FLOOD MAPPING
• HYDRODYNAMIC MODELLING
• RESOURCE MANAGEMENT
• ENGINEERING SURVEYS

23. APPLICATIONS – COASTAL SURVEYING

24. APPLICATIONS - POWERLINES
• AIRBORNE LIDAR IS USED TO MAP POWERLINES FOR:
• ASSET MANAGEMENT
• VEGETATION CLEARANCE
• ENGINEERING SURVEYS
• ADDITIONAL DATA CAPTURED INCLUDES:
• COLOUR PHOTOS (NADIR AND OBLIQUE)
• THERMAL PHOTOS – FOR “HOTSPOT” DETECTION
• WEATHER DATA – FOR ACCURATE MODELLING OF CONDUCTOR SAG

• ENGINEERING SURVEYS
• EMBANKMENT LANDSLIDE DETECTION

27. APPLICATIONS - RAILWAYS

28. APPLICATIONS - HERITAGE
• LASER SCANNING PROVIDES VISUAL AND METRICALLY ACCURATE BASE DATA FOR A VARIETY OF
HERITAGE APPLICATIONS INCLUDING
• CONSERVATION PLANNING
• CONDITION SURVEYS
• DECAY MONITORING
• RECORDING
• ARCHITECTURAL ANALYSIS

33. APPLICATIONS – ACCIDENT RECONSTRUCTION
• AFTER A FATAL ROAD ACCIDENT THE ROAD MUST BE CLOSED FOR A FULL SURVEY BY THE POLICE
• USING TRADITIONAL SURVEYING TECHNIQUES THE ROAD MAY BE CLOSED FOR MANY HOURS
• POLICE FORCES ARE NOW USING 3D TERRESTRIAL SCANNERS TO QUICKLY SURVEY THE ACCIDENT
SCENE

34. APPLICATIONS – 3D MODELS & SIMULATIONS
• LIDAR IS THE PERFECT CHOICE FOR CAPTURING 3D INFORMATION FOR USE IN THE CREATION OF
3D MODELS AND SIMULATIONS DUE TO:
• HIGH SPEED OF CAPTURE
• HIGH RESOLUTION OF DATA
• HIGH ACCURACY OF DATA
• POINTCLOUDS ARE OFTEN COLOURED TO PROVIDE PHOTOREALISTIC POINTCLOUDS TO AID
MODELLING

36. INDOOR MAPPING

37. ZEB1 - INTRODUCTION
• HANDHELD MOBILE MAPPING
• WALK & SCAN WITH ZEB1
• MEASURE >43,000 PTS/SEC
• PROCESS IN THE CLOUD
• USING SLAM SOFTWARE
• CLOUD-TO-CLOUD REGISTRATION

38. ZEB1 – HOW IT WORKS
