Özet
In this study, acquisition of spatial data for GIS with RTK-GPS and conventional survey methods have been compared in view of cost and accuracy. 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. About a 20 ha test area were established in Selcuk University Campus to compare RTK-GPS and classic methods. Detail points in the test area were measured according to polar coordinate method by using electronic tacheometry. Spatial data concerning the same area were obtained with Real Time Kinematic GPS (RTK GPS). Polar coordinate method (classical method) was accepted as a basis and compared with the spatial data obtained from RTK-GPS method in terms of accuracy and cost. As a result, it was noted that real-time kinematic GPS methods were found to be appropriate for the GIS projects requiring high accuracy (e.g., cadastral, public works, infrastructures, etc.).
