This thesis covers database creation, system design and application development for wire line telecom infrastructure within Geographical Information Systems (GIS) and concentrates on spatial decision support applications and serving wire line subscriber coordinates for emergency calls in Ankara. The main mission of the Telecommunication in the past was to serve for voice communication activities. Currently voice, internet, data and video communications are available. These new services need better bandwidth capacity and/or renewal of infrastructure with Fiber Optical cables. Telecom has a complex wire line infrastructure, both in physical and logical topology. It is important to manage this complex infrastructure to give better services with new installation and update activities. Due to these requirements Telecom infrastructure needs to be managed with GIS, which visually provide physical and logical relationships. In this study it’s aimed to build a GIS system for Turk Telekom (TT) including digitization of wire line cable infrastructure, geocoding subscribers and serving the coordinates of subscribers. The data layers are stored in Oracle Spatial Data Option (SDO) and spatial data information is kept in MapInfo MapCatalog. The data schemes for 81 provinces are created. The applications are developed with Borland Delphi version 7 and Microsoft Visual Studio 2008 .NET Framework. There are several GIS applications developed so far for the infrastructure of TT, since TT needs to know the location and quality of the infrastructure already present in the field and needs spatially to decide on areas that need maintenance including improvement, replacement, and new installations to improve the service. This study is presented as an alternative spatial decision support system for the improvement of the current infrastructure and services given to the customers, by using digitized network and geocoded subscriber data that is stored in GIS system. This study is carried out with customer participation and on site development with Telecom staff.
