TY - JOUR T1 - Environmental Monitoring of Spatio-Temporal Changes in Northern Istanbul using Remote Sensing and GIS AU - Göksel, Çiğdem AU - David, Ruusa Magano AU - Dogru, Ahmet Ozgur PY - 2018 DA - April DO - 10.30897/ijegeo.410943 JF - International Journal of Environment and Geoinformatics JO - IJEGEO PB - Istanbul University WT - DergiPark SN - 2148-9173 SP - 94 EP - 103 VL - 5 IS - 1 LA - en AB - This study aims to evaluate thelandscape transformation and the effect of the third Bosphorus Bridgeconstruction works on the natural ecosystem over seven years’ time in twodistricts, Beykoz and Sariyer, located at the northern part of Asian andEuropean Istanbul. The study applied supervised classification-maximumlikelihood algorithm to monitor land cover changes using multi-temporalsatellite data of Landsat covering study area for the years of 2009 and 2016.The overall classification accuracies are 92.36% with Kappa statistic of 0.89for 2009 and 91.25% with Kappa statistic of 0.89 for the year 2016. The currentstudy resulted with a rapid land cover change at the study area withapproximately 4% and %1 decrease in forest and green area, 2% increase in bothagricultural and urban/build up areas. Additionally, the destroyed areaincreased with approximately 1% of the study area in the 7 years period. KW - Change detection KW - Land use/cover KW - Landsat 8 OLI CR - References CR - Wu, J. 2008.
