Abstract:

The citrus plantations in the Çukurova region were determined using the Landsat 7 ETM satellite data which was acquired in three years interval. Cadastral maps of the study area were digitized prior to the field work. The enhanced images, overlaid on the cadastral maps, are used in the field to collect information such as the location of citrus orchards, varieties and ages of trees, etc., in order to form a data base for the study area. The satellite images were later classified with the supervised and unsupervised classification methods to identify the location, variety and age of the orchards. The classified images were later compared with the ground truth. The most accurate result was obtained from the unsupervised classification method which had 6 classes. With this approach, the changes in last three years were determined and citrus plantation areas had increased by 71.2 ha in the whole study area. The citrus orchards 3 years old or younger could not be discriminated. The use of Landsat 7 ETM satellite data were found to be beneficial in determining the citrus production areas as well as monitoring the changes in their distribution. Unfortunately the varieties and the species could not be determined because of the similarities in reflection values.
