This presentation will take you through New York State DOT's past, present, and future techniques of intersecting linear data. NYSDOT uses two linear referencing methods. The first is a field-posted reference marker system. The second is called milepoint. Milepoint measures are based on an odometer reading from a county line. This presentation will provide a brief description of combining reference marker and milepoint data under ArcInfo 7.x. Next, a demonstration of a new ArcView GIS extension allowing users to more easily perform line-on-line intersections will follow. Finally, some future direction for this functionality including enhancements to underlying software and the resulting end user benefits will be proposed.
