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”?

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
