Revealing the Interior – Indoor Mapping

“We were also able to create a 3D city model where you could see the above ground for the first time,” said Canter. “You could see a wide expanse of below ground stuff too from the TIMMS. We use a program that Trimble uses for its indoor data handling called RealWorks and we were able to build 3D models of the subway area, another perspective of the underground part. There is a lidar perspective with a 250 m spatial extent, all indoors. You can see we didn't cover everything indoors but we did a lot. It wouldn't be hard to finish this up in a day or so.”

A lot of indoor underground tunneling is very hard to cover with conventional techniques but Trimble got very accurate lidar data of a tunnel, including a birdseye view of going into the tunnel and the caverns, completed in approximately ½ hour at about 500 m a tunnel.


“We've done a lot of comparisons of distances measured in our lidar data sets and measured in real life and we're consistently seeing that we're getting about 1 inch relative accuracy,” said Canter. “We also consistently see that the floor plans that have been previously available are very often incorrect. So we believe this is a breakthrough in indoor GIS as it gets you a lot of indoor data quickly and accurately. It is highly mobile, thoroughly maps interior spaces and makes the cost per square foot quite a bit lower than it has been and allows you to optimize management of building resources.”

Much of the functionality used in TIMMS is existing Applanix workflow previously developed for airborne and land mapping.

From the press release: the Trimble Indoor Mobile Mapping Solution provides:


  • High-accuracy 2D and 3D maps of interior spaces
  • Reduced mapping time and associated cost
  • Visual models to optimize the management of building resources
  • Situational awareness through complete interior space mapping for build security and special event planners
  • Quick and accurate map production through complete work flow and data processing

Trimble's Indoor Mobile Mapping Solution is available on a limited basis. General availability is expected to be in the second quarter of 2010.

Top News of the Week

The Pléiades terminal has arrived and is ready to be installed at Esrange in Sweden, where it will be connected to the antenna at the receiving station in Kiruna, north of the Arctic Circle. Operated by the Swedish Space Corporation (SSC), the Kiruna station provides excellent responsiveness with its ability to receive data from satellites for up to 10 orbital revolutions a day.

This terminal is identical to those to be deployed at other receiving stations around the globe. It complements the receiving infrastructure at the headquarters of Astrium affiliate Spot Image in Toulouse, France, which comprises a receiving antenna that is already up and running and the civil receiving station that recently completed acceptance testing on 19 March.

The latest releases of Autodesk software have been enhanced with powerful new features for 3D design and visualization that will help architects, engineers and other design professionals unleash their creativity and maximize productivity. A consistent and modern user experience across the flagship products will also facilitate working with and moving between multiple Autodesk products.

Acquisitions, Agreements, Alliances

INRO and ESRI Canada announced an OEM agreement to embed ESRI's ArcGIS Engine Runtime into INRO's Emme travel demand forecasting and Dynameq dynamic traffic assignment applications and distribute the bundled software worldwide. The new agreement builds on the companies' 12-year partnership and provides a solution that allows transportation planners access to geographic information system (GIS) data and maps with ArcGIS technology directly from INRO software, without separate ESRI licensing requirements.

WeatherBug, the provider of consumer and professional weather services and operator of the largest weather observing network, announced that they have been selected as the provider of weather information for NAVTEQ Traffic.

WeatherBug data will empower NAVTEQ Traffic customers and users with accurate live, local weather and forecast information to plan departure times and travel routes. Weather conditions including rain, fog, winds, ice and snow can affect roads and driving conditions, and access to this information enables drivers to make more informed commute decisions.

ViaMichelin invest in state-of-the-art traffic data technology to set itself apart from other traffic information service providers. To this end, the wholly-owned subsidiary of Michelin has chosen PTV's transportation experts who will share their knowledge and expertise on the basis of a strategic cooperation. The aim is to provide real-time traffic information throughout France by means of floating car data, which supplement the existing permanent detectors.

Normally, the main source of data for traffic information services is provided by detector equipment installed along motorways and trunk roads. However, the detectors do not cover the entire road and information network.

In order to close this information gap, ViaMichelin uses Floating Car Data (FCD) which are transmitted from vehicles on the road, thus turning cars into mobile sensors. This technique delivers precise information about the driving speed on a specific route and converts it into detailed traffic information for the entire road network of France. Thanks to Floating Car Data, ViaMichelin can now provide its customers with additional and precise traffic information with wider and more granular coverage.

HR Wallingford is pleased to announce that, as of 23 March 2010, it acquired 100 per cent of the equity of SeaZone Solutions Limited (SeaZone) from the United Kingdom Hydrographic Office (UKHO). Combining the two companies establishes a truly world-class player in the provision of marine information to organisations involved in engineering, marine and coastal management, offshore energy and environmental protection.

The Geographical Association (GA), the geography subject association, and ESRI (UK), announce that ESRI (UK) has become the GA's first corporate member and strategic partner. This new partnership brings together ESRI (UK)'s expertise in GIS (Geographical Information Systems) and the GA's understanding of the learning and teaching of geography. With GIS now a compulsory part of the national curriculum, the organisations will combine forces to help teachers respond to the curriculum changes and introduce GIS into geography lessons.

Universal Map Group, LLC, an affiliate of Kappa Media Group, Inc. announced it has reached an agreement to acquire the assets of Mapsco, Inc., a Dallas, Texas-based publisher of regional and local maps sold principally in Texas, Oklahoma, Colorado, New Mexico, and Louisiana. Closing of the transaction is scheduled for March 31, 2010. Universal plans to retain the Mapsco name, several Mapsco retail stores and expand on its presence both within and outside of Texas by marketing under the Mapsco, Universal and Kappa brand names.

PCI Geomatics, a developer of geo-imaging software and systems, announced that it is partnering with Microsoft's Photogrammetry division, Vexcel Imaging GmbH. The alliance is designed to leverage the strengths of the two organizations to produce an end-to-end image processing system developed specifically for customers of Vexcel Imaging's UltraCam series of high-resolution digital aerial cameras and UltraMap photogrammetric software.

RapidEye announced that Procalculo Prosis has signed a contractual agreement with RapidEye to be its sole data distributor in Colombia, South America.


The Open Geospatial Consortium, Inc. (OGC) seeks public comment on the candidate OGC Sensor Web Enablement (SWE) Common Service Model Interface Standard Version 2.0. The SWE Service Model provides a common set of data types and defines a common set of interface mechanisms that can be used with other SWE interface standards.

The proposed OGC SWE Service Model 2.0 Standard and information on submitting comments on this document are available here. The public comment period closes on 25 April 2010.

Jack Dangermond, founder and president of ESRI will be a keynote speaker at this year's Where 2.0 Conference in San Jose, California, on April 1, 2010.
