Building software for reuse justifies the extra effort needed to identify and capture recurring patterns in software design, into a framework. Such recurrences of patterns exists at all levels of granularity. We report on the work in progress towards designing a GIS(Geographic Information System) framework. A GIS sub-domain is identified based on a recurring pattern. The central feature of the domain is linear spatial objects. We develop a scheme for representing linear space in urban setup. Many applications exists within the urban setup that can be best modeled with this representation of linear space. Keywords: Object oriented framework, GIS, Spatial network
