Analysis of changes in vegetation biomass using multitemporal and multisensor satellite data

Turkey has always been one of the major agricultural countries in the world. The importance of agriculture is increasing due to the growing of population in Turkey and in the world. Although the importance of agriculture in Turkish economy has been declined relatively in the time with respect to GNP (Gnoss National Product) and export, this issue keeps its importance since the high number of workforce and direct relationship between food resources and agriculture. Turkey can make its place stable among the world countries by defining the potential of harvest. Today, new technologies such as remote sensing and GIS can be used for crop estimation and crop mapping. The analyses of the changes in vegetation biomass over years is also so important and will assist in taking stable decisions for national agricultural policies. In this study, which was also undergraduate final project, changes in the vegetation biomass at the Lüleburgaz district, Kirklareli, Thrace region in Turkey was analysed using three multitemporal Landsat TM scenes and one Spot XS scene. In the analyses, different vegetation indices for observing the biomass were evaluated with the help of ground truth data. Based on the results obtained, the effectiveness of the use of multitemporal satellite imagery was outlined.
