The City of Philadelphia did not have a floor plan of their subway. They used TIMMS underground mostly on their heavy rail and subway system. Trimble was able to get data for their subway and their hard rail for some of the main floor. They also did the 15th floor of their building where they have their GIS department. The floor plan of their central subway station was created by TIMMS.

“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

    Trimble introduced the Trimble Point Creator Software for contractors, engineers, detailers, and architects supporting the building construction industry as well as mechanical, electrical, and plumbing trades. The application, available in two versions-Trimble Point Creator and Trimble Point Creator Pro-provides a platform where Computer Aided Design (CAD) users can create 2D and 3D points easily transferable to and from a Trimble LM80, Trimble MEP, Trimble TS Series Total Stations as well as other total stations. The application is compatible with popular CAD platforms such as AutoCAD, Bricscad, and ZWCad.

    Alliances, Agreements, Acquisitions

    Cadsoft Corporation announced their strategic technology alliance with
    Luxwood to deliver joint productivity solutions to the Lumber and Building Material (LMB) supplier industry.


    Bentley Systems, Incorporated announced the winners in the 2010 Bentley Student Design Competition and named professor Efrat Gilboa, B. Des., M.A., Shenkar College of Engineering and Design, Ramat-Gan, Israel, as Bentley Educator of the Year. The Student Design Competition awards technically advanced projects created using Bentley software by university, high school, and middle school students around the world, and recognizes the achievements of their educators and mentors. The program fosters interest and growth in the architectural, engineering, construction (AEC), and geospatial professions by encouraging students to explore the software and hone the skills they'll need as
    future members of the infrastructure community. The Educator of the Year award recognizes a member of the academic community who has an outstanding record of achievement and is committed to inspiring students to pursue careers in the infrastructure professions.

    New Products

    Bentley Systems, Incorporated announced the immediate availability of a Bentley Map V8i data model for airport information modeling that is compliant with Federal Aviation Administration (FAA) mapping guidelines. The new data model includes a comprehensive database schema, feature symbology libraries, and feature placement and editing rules that simplify the initial creation of, or migration to, an airport geographical information system (GIS) - accelerating the mapping, spatial analysis, and information modeling of airports.

    Integrated Environmental Solutions (IES) released an updated version of its VE plug-in to Autodesk Revit Architecture and MEP. The plug-in allows Revit 2011 users to easily export models into any of the IES Virtual Environment (VE) environmental building performance analysis tools; VE-Ware, VE-Toolkits, VE-Gaia and VE-Pro. Removing the need to re-build models, the IES plug-in greatly enhances design workflow and simulation accuracy, bringing comprehensive and integrated analysis options for all design stages to the Building Information Modeling (BIM) process.

    Informative Graphics Corporation (IGC) announced that it will be demonstrating the newest version of its Brava! 6.2 web-based viewing and collaboration tool for EMC Documentum Webtop 6.5. This release of Brava includes new redaction features, additional language support and the new, zero-footprint Brava Flash Viewer. Ideal for securely sharing documents, Brava for Documentum makes it easy to view, annotate and collaborate on virtually any file, including office and PDF documents, CAD drawings, and image files such as TIFF and JPG.

    Cadsoft Corporation announced the official release of the SAPPHIRE Structure Integration Module, a productivity add-on for Cadsoft's Envisioneer software.

    Open Design Alliance (ODA) announced the release of version 3.3 of its Teigha software development platform. In addition to the new Teigha (pronounced tee-ga) brand names throughout the software development platform, this latest release includes performance enhancements, interface changes designed to provide greater flexibility for application developers, maintenance fixes, and a new module which provides rendering support for PDF files referenced from .dwg files.

    Oracle announced the launch of Oracle's Primavera Inspire for SAP 7.0 for enhanced integration between Oracle's Primavera P6 Enterprise Project Portfolio Management and SAP enterprise resource planning (ERP) project-related modules.

    Bricsys NV, the developer of Bricscad, and
    Rösberg engineering, a leading software company for I&C (instrumentation and control) systems, announced that its Prodok software is now available for Bricscad V10. Until today, Prodok was available only for AutoCAD.

    Bricsys NV, the developer of Bricscad, announced that the beta version of Bricscad V10 for LINUX is now available.

    Bricscad V10 is recognized as the number 1 alternative CAD platform for the DWG file format. Until now, the software was available only for the Windows operating system. Since January 2010, a select number of users have tested several alpha releases of a version native to Linux. Today, Bricscad V10 for Linux is sufficient stable and has enough functionality to be released to the public as beta software.

    RAND Worldwide announced that its courseware division, ASCENT- Center for Technical Knowledge, will publish 18 courseware training manuals that have been designated as Autodesk Official Training Guides, covering a variety of Autodesk 2011 products.

    Autodesk Labs' Solar Radiation Technology Preview for Revit 2011 for understanding and quantifying solar radiation on various surfaces of the building information model.

    Solibri has developed an innovative solution called Information Takeoff (ITO). In brief, this capability allows users to collect information from the BIM file, visualize, and report it - instantly. This information can be spatial areas for area calculations, envelope of the building e.g. exterior wall areas for energy calculations, volumes, quantity takeoff and so on. This mining of the model for important data is one example of how powerful BIM can be. While the practice of modeling geometry has very tangible visible benefits, the analysis of information contained within the model is really exploiting the potential of BIM.
