Resumen
La integración de las operaciones para el análisis de redes de transporte en Sistemas de Información Geográfica (SIG) es una alternativa novedosa para la gestión y planificación de servicios en el ámbito urbano. Dotar a los Sistemas de Información Geográfica con tales herramientas contribuye a una mejor comprensión en el área de los Sistemas de Ayuda de Decisión Espacial. El módulo de redes de gvSIG contiene varias operaciones para el análisis de redes de transporte, pero no cuenta con las funciones maximizar cobertura, maximizar asistencia y maximizar mercado compartido de la herramienta Localización - Asignación. Estas operaciones son muy importantes si se quiere optimizar la cantidad de servicios de un mismo tipo necesarios dentro de una ciudado simplemente escoger los que están mejor ubica dos respecto a la demanda. En el presente trabajo se implementaron los algoritmosmencionados y se agregaron a este módulo, lo que permite efectuar un nuevo tipo de análisis con este SIG. Se presentaron las principales características de la nueva herramien ta que se añadió, así como una secuencia de pasos para su integración al módulo correspondiente en gvSIG. Se trabajó con el callejero de Sevilla, escogiendo como servicios a los colegios públicos y privados, y como demandas a los centroides censales de la ciudad, para realizar una comparación de los resultados de la nueva operación con los de ArcGIS, analogía que hizo válido el fruto de esta investigación, pues en ambos casos se llegó a la misma solución.
The integration of the operations for the analysis of transportation networks in Geographic Information System (GIS) is a new alternative for the services management and planning in the urban field. Providing GIS with such tools contributes to a better comprehension in the field of Spacial Decision Help Systems. The gvSIG networks module contains several operations for the analysis of the transportation networks, but it does not count maximize coverage, maximize attendance, maximize market share of the Location Allocation tool, very im portant if you want to optimize the quantity of services of the same type we need inside a city or to select the better located ones respecting the demand. In the prese nt work, the mentioned algorithms was implemented and added to this module. This allows us to develop a new kind of analysis for these GIS. The main characteristics of the new added tool were presented, as well as a steps sequence for its integration to the corresponding module of gvSIG. We worked with the street map of Sevilla by selecting public and private schools as services and the city census centers as demands. This was done for making a comparison between the results of the new operation and the ArcGIS results. Such analogy validated the fruit of the research, since we arrived to the same conclusion in both cases
