Several climatic parameters have been widely is used in studies conducted by quite diverse disciplines (hydrology, agriculture, ecology, forest management, meteorology etc). Reliable climatic data can only be obtained from meteorological observation centers located in a specific location. However, climatic parameters which show subjective distribution of the climatic data are needed in many ... [Show full abstract] studies. Therefore, need to obtain subjectively distributed climatic parameters using point based climatic parameters is continuously increasing. The use of Geographic Information System (GIS) in climatic studies is essential. In this study, the generation of subjectively distributed climatic data layers and utilization potentials were broadly investigated.
