Everyone uses road data. Whether it's for driving directions, transit planning, engineering design, or road operations and maintenance, we all have a need for road information in our daily lives. Most municipalities do all of these things at once, and it is challenging to build GIS solutions that work between multiple departments. One strategy for database design for road data uses vertical alignment of features. This presentation will demonstrate how multiple feature classes can be integrated to produce a variety of output datasets for different application needs. This approach provides a simple approach for managing road data along with efficient techniques in FME to output data in a variety of data models and formats.

Key Topics
● Road data - a short history
● Modernization
● Data Integration

3. Roads - a Short History
● Road centerlines for geocoding, mapping, and emergency
dispatch
○ Typically managed by GIS or Planning staff
● Also road characteristics for annual reporting
○ Segments/attributes typically managed in engineering by the
road design/build managers
● Significant interest in data from planning, traffic,
operations, roads, and transit departments

5. Basic Data Strategy
● Use fme to overlay road data and produced derived
data
○ Can extend to traffic modeling, asset reporting, etc.
● A useful alternative to linear referencing for
municipalities and other organizations
