Linear Location Translation within GIS
Defining Issue: Using a single linear location referencing method within DOTs is unrealistic and unacceptable. GIS Solution: The capability to translate spatial references within ArcView Version 2.1 using Avenue scripts and a customized user interface. Location translation is supported among the following referencing methods: spatial coordinates, street address, route-reference post-offset, and route-milepoint. Methodology: This paper discusses some of the issues that arise in the development of location translation systems. A description of the data model and database requirements of the system designed for UDOT is included. The context in which this location translation system was developed was to facilitate crash reporting in urban areas. However, UDOT has already begun to explore a variety of other transportation applications for which the location translation module will be used, including routing of field crews and support of customer complaint and response activities. Software: Avenue
scripts were written to translate linear references, customize data views, and generate reports. The system is operating within ArcView Version 2.1 on a digital database developed for Utah County.
