Patrones de Diseño para el Modelo de Redes en Sistemas de Información Geográfica

In this article, we describe two software design patterns that can be reused in the design of object-oriented geographical information systems (GIS). The first of them, called Spatial Object, captures the common structure and dynamics of the spatial entities represented in a GIS. The second one, called Spatial Graph, provides a solution to REVISTA COLOMBIANA DE COMPUTACIÓN Volumen 1, número 1 Págs. 91-104 Jonás A. Montilva / Yajaira Ramos 2 well known problems in the representation, management, and visualization of service networks in GIS. A more natural representation of a service network is achieved, when the Spatial Graph pattern is reused in the design of a GIS application. Both patterns, contribute to reduce the effort and cost of designing object-oriented GIS by providing reusable solutions to the modeling of spatial entities and service networks.
