  1. Current Uses of the Mandli Photolog Data • View Photolog Images • web based viewer, Roadview Explorer • requires the frame locations to be • integrated with geodatabase/HAS • Extract Inventory Features • features currently being extracted include: • bridges, culverts, guardrails, luminaires, • paved shoulders, rest areas, rumble strips, • signs, and turnouts • via contract with Mandli , priced per feature • extracted • in-house using Roadview 7 application • requires the feature locations to be • integrated with geodatabase/HAS • Update/Expand Centerline Network • frame locations contain all of the necessary • data items to update or create new route • centerlines (X, Y, Z, Mpt, and CDS route • number)

  2. Integrating MandliPhotolog Data Photolog Frame Locations • Geodatabase Centerline Network • CDS route number – 292000 • route name – Craig/Klawock/ Hollis Hwy • area shown – mpt 27.980 to 28.300 • Original Frame Locations • green circles – forward inventory direction • red circles – reverse inventory direction • Integrated Frame Locations • black circles – snapped frame locations on • the CDS route • extracted CDS route mpt value for each • frame location • Integrated Product • snapped frame location table is exported • to the geodatabase for use with GIS or • Roadview Explorer (web based • photolog viewer)

  3. Integrating MandliPhotolog Data Features Extracted From the Photolog Data Extracted Features Include: bridges, culverts, guardrails, luminaires, paved shoulders, rest areas, rumble strips, signs, and turnouts • Geodatabase Centerline Network • CDS route number – 292000 • route name – Craig/Klawock/ Hollis Hwy • area shown – mpt 27.980 to 28.300 • Original Feature Locations • green squares – sign locations • Integrated Feature Locations • snapped sign locations on CDS route • extracted CDS route mpt value for each • sign location • Integrated Product • snapped sign location table is exported • to the geodatabase for use with GIS, HAS, • and MMS

  4. Integrating Mandli Photolog Data Example of Extracted Features Following Integration

  5. Update/Expand Centerline Network • Frame Locations • frame locations contain all of the necessary • data items to create route centerlines (X, Y, • Z, Mpt, and CDS route number) • could be used to update a realigned section • of the centerline network • could be used to create a new route to be • added to the centerline network
