Abstract:

This paper discusses the implementation of an ArcView application at the Washington State Department of Transportation (WSDOT) for working with the Linear Referencing System (LRS). The MADOG (Mapping, Analysis, and Display Of Geographic information) application and centerline base maps are designed to be distributed through a client/server environment or on a CD to be operated at the person's workstation, desktop, or dashboard. The paper presents three custom ArcView extensions, written as Avenue scripts that were designed to: 1) access base and street centerline maps at several scales; 2) place point and linear "events" over the multiple route systems; and, 3) determine and locate the nearest milepoint value on the centerline map from GPS collected data. Also listed are some unresolved issues involved in the validation procedures and maintenance of an enterprise wide LRS for transportation related GIS applications.
