Site index is defined as the power of product and service production of somewhere. However, a forested land has actual and potential efficiency power. In the application, it is the actual site index we have determined according to several criteria. Actual situation is far from reflecting the real efficiency. The stand could have been affected negatively from various factors. The common structure seen in Turkey forests is like that. When the real situation is demanded, it is necessary to identify the potential productivity. Within the scope of site index term, site indicators and indexes for productive stands have been determined and accepted. We have sufficient information about these. However, the subject of making disordered stands and clearings is site index hasn’t been clarified. The site index of the areas in inventory studies increasing the cost are assigned using age-length data of the trees. However, this method does not provide sufficient accuracy for someone examining the area in separation of the site classes. Inferences have been made related to actual and potential site index by comparing NDVI images through satellite image data for the study area of which site index maps have been decided in the study and the relations have been searched. Actual and potential site index thematic maps have been formed for the sample study area through NDVI image data as the final outcome
