6 StreetMapper Users Geomaat, Netherlands: Highways survey Tecdawn, China: Highways survey and city model Geokosmos, Russia: Highways survey National University of Ireland: Research General Dynamics: Rapid mapping (military uses) Terrametrix, USA: Highways survey Geodigital, Canada: Highways survey Halcrow, UK: Highways survey GloMapTech, South Africa: Highways survey TKTI, Lithuania: Highways survey Estereofoto, Portugal: Highways survey

7 What is StreetMapper? StreetMapper is a result of a joint venture with German guidance and navigation specialist IGI mbh Mobile Mapping System (MMS) for surveying: Highways Coastlines Urban areas and more Generally consists of: Multiple laser scanners Multiple geo-referenced cameras High-grade navigation system

8 Why StreetMapper? Highest accuracy Most flexible system: Lifting platform Portable system Ease of use Highest performance sensors & navigation European export controlled navigation system Proven in operation: The ONLY terrestrial mobile LiDAR system that has been in field operations for over 5 years

9 Unique offering Complete StreetMapper Solution StreetMapper system Installation/commissioning Training Helpdesk support via phone & Remote support via internet Workflow & procedures development Additional integration of sensors Third party software tools

10 Technology Overview StreetMapper consists of: Multiple 2D Riegl laser scanners StreetMapper Two 360 degree scanners StreetMapper Portable - One 360 degree scanner High quality IGI navigation system (GPS, IMU & odometer) Multiple geo-referenced cameras

11 IGI Modular Sensor Systems Missionplanning Navigation GPS/IMU Sensor Management

12 Direct Inertial Aiding - DIA Direct Inertial Measurement Unit Inertial Aiding Differential GPS Speedometer Kalman Filter Position Velocity Attitude

14 Direct Inertial Aiding - DIA without inertial aiding with inertial aiding

16 Technology INS system Weight 2.2 kg Data rate 400Hz Gyro drift 0.03 /h System accuracy (dgps): Position: <0.05m Velocity: 0.005m/s Roll/Pitch: Heading: 0.007

17 Technology Laser Scanners Riegl VQ250 laser scanner 300 khz each 500m range 10mm accuracy Unlimited returns Calibrated reflectivity

18 Technology Laser Scanners - Reflectivity Amplitude (Intensity) Strength of the return signal Degrades over distance Point cloud will have low contrast at range Reflectivity Reflectivity measured in db Scanners calibrated against white diffuse target (0db) Reflectivity independent of range Point cloud has good contrast throughout

19 Amplitude Reflectivity

20 Technology Laser Scanners - Waveform Practically unlimited number of targets per pulse Minimum distance between targets is about 0.8m Deviation of pulse form recorded A high pulse deviation indicates two or more nearby targets Echo number and deviation is used to improve classification First of many or intermediate echo probably not ground Echo with high deviation probably not ground

21 Technology Custom sensor mounts Lifting platform Environmental protection Security Health & Safety

22 Technology Data Loggers Small rackmount consisting of: Scanner data logger (single laptop) Navigation data logger Video data logger

32 Typical Applications Accident Reconstruction

33 Case Study LA Corridor Project Community Redevelopment Agency of the City of Los Angeles (CRA/LA) set out in early 2009 to develop a new pedestrian-friendly and efficient transit corridor that would link the city s southern region with downtown CRA s challenge was to convey its vision to investors and the communities that would be affected by the development work The surveys for the new transit corridor would be obtained entirely through mobile scanning Diamond West (California) was awarded the contract with Terrametrix (Nebraska) as their partner using the StreetMapper mobile mapping system

34 Case Study LA Corridor Project The project would involve scanning 23 miles of streetscape, including: building facades two and four lane urban highways adjacent light rail lines 300 feet in both directions at over 180 intersections Diamond West set primary and secondary control using GPS and robotic total stations to improve the survey accuracy especially in the downtown areas The survey was driven at 20-30mph Surveyed over 2 days Over 2 billion points

35 Olympic Stadium Southern Region Downtown LA

Case Study LA Corridor Project StreetMapper consisted of: 2x Riegl VQ250 360

36 Case Study LA Corridor Project StreetMapper consisted of: 2x Riegl VQ degree 300kHz 2x Nikon D300 SLR cameras, calibrated & geo-referenced

37 Case Study LA Corridor Project Terrametrix processed the scan data using TerraSolid software: TerraScan for classification and cleansing TerraMatch to align the data to the control TerraPhoto to calibrate the cameras and colour the points Diamond West produced the CAD deliverables for CRA/LA within 12 weeks of data capture
