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”.

Existing “Floor Plans”

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

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)

Laser Scanner  LiDAR Scanner 60,000 pts/sec 15 meter range

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

Inertial Measuring Unit (IMU)  IMU maintains accurate indoor positioning.

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

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

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

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

 Extended 3d Deliverable

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