5. The Problem • No accurate, up-to-date floor plans. • No “As-built” drawings. • No scalable blueprints. • Emergency planning is difficult without up-to-date and accurate layout information. • First responders to an alarm or emergency situation are faced with entering the building “blind”.

6. Existing “Floor Plans”

7. The Solution • Trimble Indoor Mobile Mapping (TIMMS) • A mobile platform for capturing the interior “as is”.

8. What is “TIMMS”? • Trimble Indoor Mobile Mapping Solution • Equipped with: • Laser Scanners • Spherical Camera • Indoor Positioning (IMU) • GPS (optional) • Operator Console • Trimble Connected Community (TCC)

9. Laser Scanner • LiDAR Scanner 60,000 pts/sec 15 meter range

10. Georeferenced Spherical Camera • Image data collected is 360 degree and georeferenced.

11. Inertial Measuring Unit (IMU) • IMU maintains accurate indoor positioning.

13. Project Statistics • 75,000 sqft. • 12GB raw data. • 5hrs acquisition time. • 8hrs post-processing. • 3-5cm relative point accuracy. • Final product available to the customer on-line with TCC. Northwood-Kensett Vikings

20. One Map Multiple Uses • Data acquisition and mapping • 2D Floorplans • 3D Models • Other unique deliverables can be added based on detailed requirements • Data is web enabled in secure cloud computing environment • Data can be delivered on dedicated client servers as well for enhanced security

21. One Map Multiple Uses • Utilizing 360 imagery is critical for incident planning and management • Get a first person shooter view of every square foot of a facility before entering • Critical in determining sight lines and avenues of entry / exit • Ability to measure areas of interest • Hallway lengths / widths • See obstructions • Most important aspect is all data is geo-referenced • Every data point has a geographic co-ordinate associated to it making detailed planning possible

22. Extended deliverables: • From point cloud 2D and 3D drawings of physical space • dwg, dxf or custom requirements

23. Extended 3d Deliverable

24. Summary So, what is the big difference between the TIMMS solution and others? About 300 million geo-referenced data points!
