Update Info:Last Updated: June 3, 2015 (View the centerline update schedule: https://docs.google.com/spreadsheet/ccc?key=0Aj18jufMWioidENRNDhPb3VtRTFGamJfYzlPal9TNmc&usp=sharing)Contact Info:The statewide roads dataset is maintained by AGRC in partnership with local government, the Utah 911 Committee, and UDOT.Questions can be directed to Kelly Green (801.537.9079) at AGRCUsage:Transportation.Roads utilizes the Statewide Roads Data Model Standard, formally known as the Utah Transportation Data Model. The UGIC Road Centerline Sub-committee has been in the process of revising the content and structure of the Utah Transportation Data Model. The final draft of what is now being referred to as the ‘Statewide Roads Data Model Standard’ is pending approval by the UGIC Standards Committee.View the data model attribute descriptions and definitions: https://docs.google.com/document/d/1ojjqCa1Z6IG6Wj0oAbZatoYsmbKzO9XwdD88-kqm-zQ/edit?usp=sharingView the data model schema diagram: https://docs.google.com/open?id=0Bz18jufMWioiU25icDNoQWlJa2MThe Statewide Roads Data Model Standard is divided into two ‘tier’ levels:Tier Level 1 fields pertain to address location, cartography, and routing. Stewards are encouraged to maintain data that will map to the Tier Level 1 fields. The field named DOT_* are an exception, as UDOT will maintain these themselves.Examples of the CARTOCODE (formally CFCC) field descriptions:1 – Interstates2 – US Highway, Separated4 – Major State Highway, Separated7 – Ramps, Collectors9 – Major Local Roads, PavedTier Level 2 fields pertain to local agency maintenance and inventory and are utilized and shared if the local steward chooses to do so.Changes to the data model include a more logical approach to the ordering of fields and their names, in addition to the removal of multiple redundant fields. Proposals by the UGIC Standards Committee are meant as suggested ‘best practices’ and are primarily designed for data transfer and sharing. It is not the intent that all stewards will change their current data management process to match this standard, but rather that stewards will evealuate their current practices to see how well their data ‘maps’ to this schema for data sharing purposes. Questions can be directed to Kelly Green (801.537.9079) at AGRC.The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter coordinate precision). |
