Abstract: An important feature for geographic systems is to identify directional relationships between objects stored in Spatial Database Management Systems (SDMS). This feature is used with other information type, such as Metric and Topological Relationships. This features group provides relative positioning between Geographical Objects in some direction, and supports decision makers job, such as to decide where setting up certain buildings, opening of access roads, and installation of transmission towers, for instance. Some approaches addresses to direction definition, but without implementation. Cone-Over-Projection Directional Model (COP Model) refines directions definition and enhances spatial queries accuracy in a significant form. The Model has a computational tool to support its application. This work presents the COP Model implementation through COP Viewer (COP-VW) application that uses Geometric Algorithms added to an SDMS located in a Web Server. Several users can access COP Model re sources at different geographical locations, and different geodatabases can be available to environmental and urban planning decisions. This is a first step to migrate COP Model to mobile platform. (More)
