| Özet |
| A key step in natural resource management is the delineation of land units that are similar relative to type, structure, and productivity of vegetation in a given area. This is accomplished by land classification system on the basis of satellite images with appropriate specifications that serves as an essential database for forest management planning. Managing forests on an ecosystem basis relies upon accurate estimation of forest land classification that responds in a similar manner to management practices. The integration of remotely sensed data into a GIS offers a wide variety of new perspectives and possibilities for the analysis, evaluation and interpretation of such data, in combination with auxiliary digital information maps. The aim of this study is to compare accuracy of classified data with land use maps reclassified from the stand type maps. Two forest planning areas, Artvin and Bulanıkdere Forest Planning Unit (FPU) in Turkey, were selected as case study areas. Two land use maps were produced using Landsat ETM+(2000) data and reclassified the stand type maps. The results suggest that accuracies of classified Landsat ETM+ for Artvin and Bulanıkdere FPU are 82.14 and 88.75%, respectively. Later, classified Landsat ETM+ data were converted to vector database. Landsat ETM+ data and reclassified stand type maps were overlaid the appropriate spatial analysis carried out using GIS. As a result of spatial analysis, accuracy of vectorized Landsat ETM+ data is around 5-10%, lower than classified Landsat ETM+ data. In addition, according to land use map derived from stand type map, accuracy of land use map derived from Landsat ETM … |
