One of the main components of a Geographic Information System (GIS) is the formation of the database. More than 70% of the time and cost is spent on developing this database. The success of a GIS project depends on the accuracy and currentness of the obtained spatial data required for development of the GIS project. This study presents analyses of the accuracy and costs of several methods of obtaining spatial data for a GIS project in a test area selected at the Campus of Konya Selcuk University. The conventional and Real Time Kinematic Global Positioning System methods were found to be appropriate for GIS projects requiring high accuracy (e.g. cadastral, public work, or infrastructure projects). On the other hand, photogrammetric methods, digitising and scanning, and high resolution satellite images (remote sensing) were determined to be the most suitable methods for GIS projects requiring lower accuracy over large areas (e.g. in environmental management, highways, railways, forestry, disaster management, land consolidation).
