Agenda

• Background• Asset Problem

• Technology• Review Possible Technologies

• Innovation• Solution

• Partnerships• Review of Partnerships

• Implementation• Penta Career Center• How Things Were Conducted• Benifits

• Results• Collection Results

• Questions

Background - ODOT District 1 and 2

• Northwest Ohio• District 1

• John Puente GIS Coordinator

• District 2• Fred Judson GIS

Coordinator• Serving 16 counties• 7167 Lane Miles• 20,086,539 Miles Traveled

Yearly• 2031 Bridges

Background - Asset Problem

• What Quantity?• Where Is It?• How Old Is It?• How Many Times Have We Performed Maintenance To It?• What Is Its Life Expectancy?

Background - Asset Collection

Business Requirements• Asset Type

• Safety Related• Guardrail, Signs etc.

• Accuracy• Location On Earth• Collection Quality

• Frequency• How Often Does It Need Updated

• Cost• Restrictions

• Technology Limitations• Right Collection Tech. For The Asset

Technology For Collection• Remote Sensing

• LiDAR, Aerials etc.• GPS

• Mapping, Survey, Cell Phones• Inferential Statistics

• Calculate Base on Sample Sets

• 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

Technology - Asset Collection – Remote Sensing Methods

• Satellite Imagery• Some Free• Good Stuff Costs Big $$$• Most does not meet our resolution needs.• Limited By Weather

• LIDAR• OSIP LIDAR Very Accurate• 1 Meter spacing did not meet our resolution needs.• Freely Available

• Oblique Aerial Imagery• Most does not meet our resolution needs.• Expensive

• Orthorectified Aerial Imagery• Most does not meet our resolution needs.• Frequency of coverage is dependant of source.

Technology - Asset Collection – Remote Sensing Methods - ODOT Video Log

•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 - Asset Collection – Methods

• Identified Assets• Identified Collection Methods• Prioritized Asset Collection• Identified Update Procedures

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

Innovation - Build Our Own Asset Capture Software

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.

Innovation - Mobile Video Asset Capturing Application - Image Calibrations

Innovation – Asset Capturing

• Capture Any Asset• Video• Aerial

• Intelligent Attribute Forms• Efficient

Asset Data Entry

• Reposition• Video• Aerial

Innovation – Navigation

• Efficient Navigation

• Available For The Entire State

Innovation – Asset Capturing

• View Any Video Cycle

• 2 Different Vendors

• 3 Different Years

• Over 5 Terabytes Of Data

• Millions $$$ Invested

Innovation – Measurement

• Measure On Image• Vertical• Horizontal

• Measure on Aerial

Innovation – Zoom And Street View

• Zoom Any Portion Of The Image

• Link To Google Street View• Additional

Reference

Innovation – Extended Use

• Data Integration

• Spatial Querying

• Reporting• Linking To

Other Datasets

Partnerships

Partnerships - Penta County and Rhodes College Sign Asset Collection

• Training and collection started 4/15/2010• Penta County High School GIS Program

• 22 Students – Juniors and Seniors• OSU Lima Campus GIS Majors

• 2 Students from OSU – Lima Campus• Student Benefits

• Real World Experience• Working With Cutting Edge Software

• ODOT Benefits• Capture of our sign assets.• Develop workflows and benchmarks for internal collection.• Developed a method to access potential resources that not only helps ODOT but also helps Ohio’s Future.

Implementation

• ODOT officials providing the training.

Implementation

• Students learning the details for collecting the sign data:

Results

• Students collecting asset data. • Collection Period : 4/15/2010 to 5/25/2010

• Total: 6699 Signs• Value: $466,054• 200-500 Average Per

Session
