Abstract

In recent years, a large number of studies have been carried out on determining geological characteristics using remote sensing studies and their usefulness. The integrating satellite images and terrestrial spectral data are used distinguishing lithologies in geological units. The use of remote sensing images helps to save time and to reduce the cost of mapping works. In this study, the usability of ASTER SWIR images in distinguishing rock types and in determination of contacts between lithological units in Kösedağ area between Zara and Suşehri towns of Sivas Province. Syenitic, andesitic, basaltic and ophiolitics rocks are cropt out in this area. Spectral signatures of the representative samples from these rock types were measured via ASD spectroradiometer. The signatures were resampled to ASTER SWIR bandwidth as end member. Matched filtering method was performed on the images for spectral classification. The results showed that distinguishing of the mentioned rock types is possible and the boundaries between rock types on the spectral images are mostly coincided with the boundaries on the 1:100.000 scale geological map of the study area

Özet

Son yıllarda, jeolojik özelliklerin uzaktan algılama ile belirlenmesi ve yararlılığı konusunda çok sayıda çalışma gerçekleştirilmiştir. Jeolojik birimler içindeki kaya türlerini ayırtlamak için uydu görüntüleri ve yersel spectral ölçme verileri kullanılmaktadır. Uzaktan algılama görüntülerinin kullanılması harita çalışmalarının maliyetini düşürmekte ve zaman tasarrufu sağlamaktadır. Bu çalışmada, Sivas ili Zara ve Suşehri ilçeleri arasında yer alan Kösedağ yöresinde kayaç türlerini ayırtlamak ve litolojik birimler arasındaki dokunakları belirlemek için ASTER SWIR görüntülerinin kullanılabilirliği araştırılmaktadır. Bu sahada, ofiyolitik, andezitik, bazaltik ve siyenitik kayaçlar yüzeylemektedir. Bu kayaç türlerinden alınmış temsili örneklerin spektral özellikleri/belirteçleri ASD spectroradyometre ile ölçülerek belirlenmiştir. Belirlenmiş özellikler, referans spektra ASTER SWIR bant dalga boyu aralıklarına yeniden örneklenmiştir. Spektral sınıflandırma için eşleşen filtreleme (Matched filtering) yöntemi uygulanmıştır. Sonuçlar, belirtilen kayak tiplerinin ayıtlanmasının mümkün olduğunu ve aralarındaki sınırların inceleme alanının 1/100.000 ölçekli jeolojik haritası üzerinde çizilmiş dokunaklar ile çakıştığını göstermiştir
