| Özet |
| In this study, a new methodology, based upon Local Climate Estimator (LOCCLIM) free software of Food and Agricultural Organization (FAO) of the United Nations (UN), was developed to create the climatic maps of Nallιhan Region in Turkey. Suggested methodology improves the spatial resolution quality of the derived climatic data and contains the steps that show how climatic surfaces can be established in geographic information system (GIS) environment. For this purpose, total 570 points (sites) were established with 0.01 decimal degree (∼1000 m) grid intervals on the map of study area. Then, climatic variables (temperature, precipitation and potential evapotranspiration) of each point was derived by using LOCCLIM and (user defined) digital elevation model (DEM) with 1/25000 scale. Finally, climatic maps were developed by using derived point data and Inverse Distance Weighted Average (IDWA) method in GIS. To test the developed climatic surface maps, linear regression analyses were conducted with the original climatic data. Additional climatic surfaces were produced by using regression equations, DEM and map calculation functions of GIS. All developed climatic maps originated from LOCCLIM were subtracted from the corresponding regressed surface maps. The differences were found low for temperature variables, when some great differences were detected for the other climatic variables. Results showed that LOCCLIM supplied a strong background as a worldwide database source and software and proposed methodology could be a good solution to create the temperature related continuous surfaces. On the other hand, it is concluded that users should be cautious when they are working with precipitation and potential evapotranspiration variables. © 2007 Asian Network for Scientific Information. |
