NOAA AVHRR VERİLERİNİ KULLANARAK TÜRKİYE’DE BİTKİ ÖRTÜSÜNÜN İZLENMESİ VE İNCELENMESİ

Abstract

Turkey represents a considerable range of biodiversity due to its location in the World. Several types of forests and grasslands are the main vegetation formations of Turkey, but there are many other secondary vegetation areas in the country. The distribution of the different formations is controlled largely by climate and topography. The main objective of the study is to examine the utility of NOAA AVHRR data (which were collected for the years of 1992, 1993 and 1995) for monitoring vegetation conditions in Turkey. The NDVI is calculated and the data are composited for selected temporal periods to evaluate vegetation state. The results showed that the frosted areas, which have larger amount of biomass, represented high NDVI; on the other hand grassland areas had low NDVI. Grassland areas reached peak NDVI level during at the and of may and beginning of June in the Interior Anatolia, in contrast Eastern Anatolia has reached the peak NDVI at the end of June
