  2. NCHRP Geospatial Synthesis Project Use of Advanced Geospatial Data, Tools, Technologies, and Information in DOT Projects Social media – international exposure TRB Report 446 http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_syn_446.pdf

  3. NCHRP 15-44 Guidelines for the Use of Mobile LIDAR in Transportation Applications MPN Components, Inc. Persi Consulting

  4. The Team • Dr. David Hurwitz (OSU) • Keith Williams (OSU) • HalstonTuss (OSU) • Dr. Mike Knodler (Innovative Data) • Anthony Squellati (DEA) The Timeline Project officially began September 2011 - Completed December 2012 Dr. Michael Olsen (OSU), PI Dr. Gene Roe (MPN Components) Dr. Craig Glennie (U of Houston), Co-PI Dr. Fred Persi (Persi Consulting) Marcus Reedy (DEA)

  5. Transportation Asset Lifecycle

  6. Presentation Overview • Project Objectives and Motivation • Establish Baseline • Management Considerations • Applications • Level of Detail • Decision Flow Chart • Benefit\Cost • Implementation Plan • Technical Considerations • Factors Affecting Accuracy • Data Management • Deliverables and Documentation

  7. Project Objectives & Motivation • Appropriate, intelligent mobile LIDAR use • Cost effective adoption of mobile LIDAR • Common basis for communication between data providers and users • An easy-to-understand management-level approach, with guidance on quality management and specification of final deliverables

  8. Objectives & Motivation – Cont’d. • Adequate metadata and methods documentation • Data management, storage, persistence and compatibility to ensure long term viability of captured datasets. • Mobile LIDAR expertise not expected, but… • Technology agnostic, yet relevant to existing COTS

  9. Mobile LiDAR Guidelines - eLearning Extension • TRB Report 748 -http://www.trb.org/Main/Blurbs/169111.aspx • Website – see preview (maybe) • User Forum, Wiki, eLearning Modules and more • Webinars – 3 • The Guidelines, Management, Technical • Online Courses – 5 modules • Overview, Tech/Apps, Procurement, Data Management, Quality Management

  10. Where Would We Be Without Standards?

  11. E 57.04 Scope – Data Interoperability To develop and promulgate open, standard data exchange mechanisms for 3D imaging system - derived data in order to promote its widest possible use.

  12. ASTM E57 Data Exchange Format ASTM E2807-11 Standard Specification for 3D Imaging Data Exchange Not a working format All major vendors are supporting Extendable Reference implementation is available Goals Cross-platform Open source http://www.libe57.org • Foundation API – Comprehensive • Simple API – Easy to use, designed for common use cases

  13. LandXML and TransXML • Data formats, not models • LandXML is being moved to OGC; flavors • TransXML • NCHRP 20 – 64 (2006) • XML Schemas for Exchange of Transportation Data developed a set of Extensible Markup Language (XML) schema for transportation applications in a framework called TransXML • www.transxml.org

  14. Master Vision – An Integrated Built Environment Data Model • Scale - from the globe to your desk • Not trivial – transformative change • Many components including land, water, utilities, buildings , transportation • 3D of course • CityGML, LandXML building blocks • Think BIG - Google

  15. TDM – Transportation Data Model • Focus on the transportation component • Fertile ground – CAD and GIS being used to represent the same assets • Borrow from BIM – changed the world • Integrated CAD with database • Lifecycle approach

  16. Benefits of a Data Model • Communication and precision are the two key benefits that make a data model important to applications that use and exchange data. • A data model is the medium which project team members from different backgrounds and with different levels of experience can communicate with one another. • Precision means that the terms and rules on a data model can be interpreted only one way and are not ambiguous.

  17. Centralized Spatial Data Management

  18. Once in a Generation Opportunity • Transitioning from 2D to 3D graphics world • From linear referencing to Lat/Long (GPS) • 10 year process – just in third year • Maximize ROI – Utah DOT Asset Management Program (Stan Burns) • BIG Idea – change the world • Transformative change – status quo is not working – FHWA Every Day Counts

  19. Utah DOT – “Good Roads Cost Less” • Recently mapped the entire state – 6,000 + center lane miles • Asset management primarily, but multiple groups supported effort • Safety, maintenance and preservation • Mobile LiDAR, video, laser road imaging, etc. • Huge data management challenge • UPLAN – Public planning platform - http://uplan.maps.arcgis.com/home/

  20. A Path Forward • Complex, painful, but rewarding • Technical part is easy – it’s the will to change that is extremely hard • TRB funded project to develop the transportation agency data model • Tie into MAP-21 and Every Day Counts (FHWA) • Could be tied to revenue generating model
