Evaporate mapping in Bala region (Ankara) by remote sensing techniques

Abstract

Evaporate minerals are important industrial raw materials used in diverse industries for years. One of the extensively used evaporate mineral gypsum has become very common raw material in construction, agriculture, textile, dentistry and chemical industry in recent years. In coherence with its common use especially in construction industry as plaster, demand to these minerals rises each following year. The aim of this study is to further develop thermal image processing methods to identify gypsum minerals. For the remote sensing analyses ASTER images which have high spatial and spectral resolution are used. Ankara Bala region has well known outcrops with operational mines and mapped in detail by the studies of MTA so that this region is selected as the test area.
