Infrastructure services, such as wastewater, water, natural gas, electricity and telecommunication services are the major application areas of UIS (Urban Information System). In Turkey, since the population in urban areas has been increasing rapidly and uncontrollably, infrastructure services have been extremely insufficient. After the destructive earthquake which happened in the Marmara region on 17(th) August 1999, the infrastructure system was seriously damaged. Use of GIS (Geographical Information System) has been an indispensable tool to control the infrastructure services more efficiently in case of such emergencies.
