Abstract

This study aims to evaluate the
landscape transformation and the effect of the third Bosphorus Bridge
construction works on the natural ecosystem over seven years’ time in two
districts, Beykoz and Sariyer, located at the northern part of Asian and
European Istanbul. The study applied supervised classification-maximum
likelihood algorithm to monitor land cover changes using multi-temporal
satellite data of Landsat covering study area for the years of 2009 and 2016.
The overall classification accuracies are 92.36% with Kappa statistic of 0.89
for 2009 and 91.25% with Kappa statistic of 0.89 for the year 2016. The current
study resulted with a rapid land cover change at the study area with
approximately 4% and %1 decrease in forest and green area, 2% increase in both
agricultural and urban/build up areas. Additionally, the destroyed area
increased with approximately 1% of the study area in the 7 years period.
