| Abstract | A system for visual spatial queries in Geographical Database (GDB) is characterized by the use of graphical representations that aim to abstract the syntax of the query language of the GDB. Web mapping is a service available on the Web that allows creating and displaying maps and routes from a Website. In this context, despite the popularity of Web Mapping Services (e.g., Google Maps, Yahoo Maps, and Maps Bing), these tools were not designed to perform spatial queries (e.g., topological, directional and metric) in a GDB. Aiming to offer an alternative to this limitation, this dissertation implements and specifies the Visual Spatial Query (ViSQ) system, which uses a Web Mapping service to perform spatial queries in a visual GDB. The ViSQ makes use of open, extensible and standard technologies, such as Java, XML and SQL. As proof of concept, we executed a case study with real data from the electricity sector that shows the viability of the ViSQ system. |
