The Single Line Street Network (SLSN) is a model, or abstraction, of the drivable surface and selected linear features in a city or a region. The major roles of the SLSN in Mobile Geographic Information Systems (GIS) are 1) to provide the underlying framework of positioning and navigating vehicles; 2) to provide location reference to road related information; 3) to act as a visual index for display and query; and 4) to link to attribute information. The SLSN is no longer just a graphical representation of the road layout but an intelligent, topologically structured database. This paper describes the construction of the SLSN in the City of Scarborough, its data model, data loading and maintenance issues, and how the SLSN can relate attributes to spatial objects for vehicle navigation and information systems (VNIS). This paper also examines a municipal government's contribution to VNIS and its view on partnership with private sector and external agencies in building a Mobile GIS.
