An Approach to Comparing Different Land Evaluation Methods with NDVI

Abstract

Land evaluation is a necessary process for determining the potential cabilities of the land under different uses and for sustainable soil fertility.Today, many land evaluation models are being developed and using for this purpose. But the availability of models is constantly being investigated by the researcers. In this study, Storie Index (SI) and Productivity Index (PI) models were compared with NDVI values which is a remote sensing analysis in Konya Besgozler agricultural field on the GIS environment. In the results of the study, SI land evaluation model was determined with higher accuracy coefficient (r 2 : 0.86) as far as PI model (r 2 : 0.29) to the ability of the soil cability depends on the density of vegetation and the use of this model is recommended for Arid region soils.
