Abstract

The Sentinel-2A satellite is a multispectral instrument with medium spatial resolution (10-60 m) developed by ESA. In general, one of the tasks of the satellite is also mapping process of land cover and use. In recent years, different studies have been conducted to demonstrate the adequacy and potential of Sentinel-2A MSI (MultiSpectral Instrument) satellite sensors. In our country, the limited studies done by the Sentinel-2A satellite images reveal the importance of this study. The main purpose of this study is to determine the temporal change of land use and land cover of Giresun province using Sentinel-2A satellites. In this context, the satellite images covering Giresun province center from Sentinel-2A satellite for 2017 and 2018 were obtained from ESA's data provider web address. The land cover changes for the years were determined and the losses and gains of the land classes were calculated. In practice area which is about 29 km 2 , it is generally determined that green and construction sites are replaced within the area. In addition to this, it is calculated that approximately 63 hectares have been passed from the green areas to the construction sites As a result, the usage of Sentinel-2A satellite images, which provide free access, has been demonstrated in the determination of land use and land .

Özet

Sentinel-2A uydusu, orta konumsal çözünürlüğe (10-60) sahip olan ve ESA tarafından geliştirilen süper spektral bir araçtır. Genel olarak bu uydunun görevlerinden bir tanesi de arazi örtüsü ve kullanımına ilişkin haritalama işlemleridir. Son yıllarda Sentinel-2A MSI (MultiSpectral Instrument) uydusunun yeterliliğini ve potansiyelini göstermek amacıyla farklı çalışmaların yapıldığı görülmüştür. Ülkemizde ise Sentinel-2A uydu görüntüleri ile yapılan çalışmaların sınırlı kalması, bu çalışmanın önemini ortaya koymaktadır. Bu çalışmada, 2017 ve 2018 yıllarına ilişkin Sentinel-2A uydusundan Giresun il merkezini kapsayan uydu görüntüleri, ESA’nın veri sağlayıcı web adresinden temin edilmiştir. Yapılan çalışmada bu iki yıla ilişkin arazi örtüsü değişimleri belirlenmiş olup, arazi sınıflarının kayıp ve kazançları hesaplanmıştır. Yaklaşık 29 km 2 ’lik alanda gerçekleştirilen uygulamada, genellikle yeşil ve yapım alanların kendi içerisinde yer değiştiği belirlenmiştir. Bununla birlikte yeşil alanlardan yapım alanlarına da yaklaşık olarak 6300 pikselin geçtiği hesaplanmıştır. Sonuç olarak ücretsiz erişim imkânı sağlayan Sentinel-2A uydu görüntülerinin, arazi örtüsü ve kullanımının belirlenmesinde olumlu sonuçlar verdiği tespit edilmiştir.
