A study on the determination of electromagnetic reflection values of agricultural crop pattern to improve accuracy of land use map by remote sensing technique

Abstract

With this study, using remote sensing technique, a data base which covers data on the electromagnetic energy reflections of various kinds of plants has been formed with the purpose of determining crop patterns. A 1/5.000 scale cadastral map was used as topographic map for the purpose of using remote sensing technique more effectively and sensibly for such crops as cotton, maize and sun flower of which the agriculture is exercised widely in Torbali township and in this context in all the Aegean Region. In the current study, August 2001 dated Landsat 7 satellite images of the region were interpreted and ground realities and satellite images of the agricultural crops with high economic value which are widely cultivated in the region were overlapped and their values of reflection were determined. Images thus obtained were overlapped with 1/5.000 cadastre maps and product varieties could be determined at the basis of large section of a map, plot and parcel. Separately collaboration with technical personnel from the Directorate of Torbali Township Agriculture was achieved in field and lab studies, and by transferring the data obtained into their computers, tangible steps were taken in the direction of applying technology at the basis of the Township. As a result, an important and basic database was formed that could be used for the payout of incentive premiums to the local organization for various crops or that could render functionality to the implementation of Agricultural policies based on record system.
