Objectives & Themes

Objectives

• Establish a standard for managing and governing data in spatial and linear referencing systems at transportation agencies, including but not limited to routes, intersections, interchanges, roundabouts, road segments, roadway characteristics, infrastructure assets, model inventory of roadway elements (MIRE), HPMS data items and ARNOLD road network.
• Develop guidance for States for engineering spatial transportation data and preparing it for sharing and provisioning at the enterprise level, across various business functions and stakeholders at the DOT and their Federal, State and Local partners.
• Conduct a series of webinars, workshops, peer exchange meetings and provide consulting services to the States participating in the pooled fund to develop national standards in data modeling and management; enhance existing enterprise GIS systems at these agencies.
• Update the AEGIST Guidebook that was prepared in Phase 1, by documenting best practices, patterns and similarities across agencies in managing spatial data using enterprise data systems, including but not limited to Asset Management Systems, Traffic and Safety Systems, Project Planning and Programming Systems, Design and Construction Systems, and GIS and Linear Referencing Systems (LRS).
• Collaborate with States to enhance and develop spatial data management systems, processes, platforms to establish a structured and systematic approach for management of spatial data. This would involve establishing spatial data governance systems, business rules, applications, tools and platforms for:
  • Spatial Data Modeling
  • Spatial Data Integration and Engineering
  • Spatial Data Analytics

Themes
