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 Source: http://www.terrametrix3d.com
- 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
- 26. APPLICATIONS - RAILWAYS • APPLICATIONS INCLUDE: • ASSET MAPPING • CLEARANCE MAPPING (CLASH DETECTION) • ENGINEERING SURVEYS • EMBANKMENT LANDSLIDE DETECTION
- 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 • ARCHAEOLOGICAL INVESTIGATION • SITE PRESENTATION
- 30. APPLICATIONS – VEGETATION MAPPING • VARIOUS TYPES OF INFORMATION CAN BE EXTRACTED FROM LIDAR INCLUDING: • CANOPY HEIGHT • CANOPY VOLUME • SUB-CANOPY TOPOGRAPHY • BIOMASS • STEM DIAMETERS
