• Through Work Orders• Collect when work is performed to it.
• Project Inclusion• Require contractors to collect after a project is completed.

Background - Asset Collection – Current Practices
• Multiple Data Formats• No Standardizations \ Localized Standards• Log Point As Primary Spatial Reference
•1 mi = 5280 ft Most Locations Carried To .01 = At +/- 52.8’• Average Error In Log Point +/- 300 ft.• Mile Marker Signs Would Be Placed Wrong• Mile Marker Signs Would Not Be Recorded Correctly• Locations Recorded By Multiple Methods
• Landmark, County Log Point, State Log Point And Intersection

Background - Asset Collection – GPS Devices
2nd Most common location referencing method used by ODOT is GPS.Pros
• Accurate Locations• Electronic Upload• Customizable Applications
Cons• Requires Specialized Equipment And Software• Requires Logistical Planning• Compounding Deadhead Times For Complete Coverage• Requires Specialized Training• Subject To Weather Conditions• Increased Safety Risk To Field Crews And Public
•Video Log as a remote sensing method for asset inventories.
• Good Update Frequency• Established Internal Business Process• Cheap To Implement
•ODOT Video Log• Occurs Every 3-6 Years• Process Is In Place• Possible to project coordinates into image.• The van has a GPS.• We did not have software to accomplish our needs.
Technology - Video Log Applications - Video Vehicles

Technology - Video Log Applications - Vendor Evaluations
• Evaluated Several Vendors With Video Log Solutions For Asset Extraction• Researched Extensively• Found Vendors At Extremes (Good and Bad)• Hard Part Was Finding Their Actual Capabilities• No one knows our business better than us.• All were too expensive for the district.

Innovation - Asset Collection – Methods
15Ohio Department of Transportation District Two
Innovation - Build Our Own Asset Capture Software
16Ohio Department of Transportation District Two
Innovation - Software Requirements
• Web Based For Scalability• Throughout District Office 1 And 2, And County Garages
• Flexible• We can add delete or change any asset any time.
• Independent From Any Vendor• We will be able to use this with any video vendors’ image.
• User Friendly• Asset collection is accomplished by a few clicks.
• Leverage Existing Resources\Investments
• OGRIP – LBRS\OSIP\VRS

Innovation - Mobile Video Asset Capturing Application - Image Calibrations
• Issue• We were not sure of the camera configurations for the different video cycles.• We attempted to measure everything our selves and found that we could not be accurate enough.
• Solution • By manipulating Tao’s equations and coming up with a few of our own we were able to develop methods to develop a configuration for each video cycle.• Uses the imagery with known points and measurements to calibrate.
