    Hoy en d铆a los Sistemas de Informaci贸n Geogr谩fica (SIG) se utilizan ampliamente al interior de las empresas para la gesti贸n de la informaci贸n espacial. Usualmente, el desarrollo de estos sistemas y sus bases de datos se realizan de manera aislada, generando inconvenientes a la hora de intentar compartir los datos y las funciones entre ellas. Este problema evidencia la necesidad de buscar opciones de interoperabilidad鈥攄efinida 茅sta como la capacidad de los programas para compartir sus datos y procesos de manera que haya poca o nula intervenci贸n del usuario鈥攅ntre los SIG. Existen varios esfuerzos realizados en esta direcci贸n, principalmente a nivel sint谩ctico y sem谩ntico, clasificados en cuatro grupos principales: 1) la definici贸n de est谩ndares, 2) la elaboraci贸n de ontolog铆as en el dominio SIG, 3) el desarrollo de servicios web y 4) la implementaci贸n de computaci贸n grid. En este art铆culo se realiza un an谩lisis conceptual de los trabajos realizados en cada clasificaci贸n, se sintetizan los aportes identificados y se presenta un resumen mediante un esquema preconceptua

    Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system鈥檚 utilization
