u çalışmada farklı kaynaklı
(Sentinel-1, Sentinel-2 ve Landsat-8) uydu görüntüleri kullanılarak
Azerbaycan’ın Bakü kıyılarındaki tabii ve insan kaynaklı sızıntılar
incelenmiştir. Sentinel-1 Yapay Açıklıklı Radar (SAR) görüntüleri açık kaynaklı
Sentinel Uygulama Platformu’nun SNAP 6.0 yazılımı kullanılarak işlenmiş ve
değişik tarihli petrol kirliliği olan alanlar tespit edilmiştir. Bu
sızıntılardan en büyüğü 465 kilometrekare alan kaplayan 19 Ocak 2018 tarihli
görüntüdür. Sentinel-2 görüntüsü de SNAP yazılımı kullanılarak işlenmiş, obje
temelli analiz (OBIA) uygulanarak kirli alanlar tespit edilmiştir. Landsat-8
uydusu ACOLITE yazılımı kullanılarak işlenmiş ancak istenen sonuçlara
ulaşılamamıştır. Çalışma sonucunda farklı kanallı uydu temelli izlemenin,
denizel ortamdaki petrol kirliliği ile ilgili bilginin toplanması,
görüntülenmesi ve analizi için etkili bir yöntem olduğu ortaya çıkmıştır.

Monitoring Oil Pollution of Caspian Sea Coastline of Bakü, Azerbaican by Using Multi-Sensor Based Approach

Öz

In this
study Multi-Sensor (Sentinel-1, Sentinel-2 and Landsat-8) based approach is
used to investigate natural seepage and manmade oil pollution in the Caspian
Sea along the coast of Bakü, Azerbaijan. The processing of the satellite images
was carried out using the sentinel application platform (SNAP, 6.0), which is
an open source common architecture and oil pollution for different dates was
determined. The largest oil seepage was detected on January 19, 2018 that
covered almost 465 square km. Sentinel-2 image was also processed by SNAP 6.0
and by using object-based image analysis (OBIA) the polluted areas were
determined. ACOLITE software was used for processing however did not provide
expected output. As a result of this study, it was determined that multi-sensor
based satellite monitoring is an efficient approach for the collection,
visualization and analysis of information on oil pollution in the marine
environment.
