Some applications of satellite remote sensing to environmental monitoring in Turkey

Determination of runoff coefficient of basins by using geographic information systems Acınan, Sezen; Usul, Nurünnisa; Department of Geodetic and Geographical Information Technologies (2008) Turkey has very different geomorphologic, hydrologic and climatic conditions, so the runoff coefficient should be different from one basin to another. But only one constant value, which is 0.37, is being used for all the basins in Turkey. In this thesis, monthly, seasonal and annual runoff coefficients of 48 sub-basins in western and southern part of Anatolia are determined by using synchronous and average rainfall, runoff data of 26 year record period. Their temporal and spatial distributions are investiga...
Direct georeferencing and orthorectification of airborne digital images Kiracı, Ali Coşkun; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2008) GPS/INS (Global Positioning System / Inertial Navigation System) brings possibility of relaxing the demand for aerial triangulation in stereo model construction and rectification. In this thesis a differential rectification algorithm is programmed with Matlab software for aerial frame camera images. This program is tested using exterior orientation parameters obtained by GPS/INS and images are ortho-rectified. Ground Control Points (GCP) are measured in the orthorectified images and compared with other rect...
Real-time snow cover mapping over mountainous areas of Europe using msg-seviri imagery Sürer, Serdar; Şorman, Ali Ünal; Department of Geodetic and Geographical Information Technologies (2008) An algorithm has been developed for snow recognition (SR) over mountainous areas of Europe from satellite imagery. The algorithm uses Meteosat Second Generations (MSG) instrument Spinning Enhanced Visible and Infra-Red Imager (SEVIRI) data that are acquired in every 15 minutes through whole day. Although SEVIRI has low spatial resolution, its high temporal resolution provides a better discrimination capacity between ice clouds and snow. Discrimination of snow and clouds is the most challenging part of snow ...
The Impact of GCR on Local Governments and Syrian Refugees in Turkey Kale Lack, Başak (Wiley, 2019-12-01) In the last couple of years, more than 3.6 million Syrian refugees have been hosted under the "temporary protection" scheme in Turkey. Despite these high numbers Turkey did not have a centralized refugee settlement and integration policy. As a result, various stakeholders including local governments have played critical roles in providing refugee assistance services. This research looks at the role of local governments in delivering services evolving from emergency response to local integration. This articl...
Temporal evaluation of snow depletion curves derived for upper euphrates basin and applications of snowmelt runoff model (srm) Marım, Gökhan; Şorman, Ali Ünal; Department of Geodetic and Geographical Information Technologies (2008) Water is becoming very important issue day by day with descending usable water and energy resources. In the aspect of water resources management, especially for the optimum reservoir management, predicting runoff for large reservoirs by applying hydrologic model is a recent and crucial topic. The most important model input and predictor parameters to estimate runoff for the mountainous regions are to be distribution of rainfall; temperature and snow cover area, (SCA). It is seen that many predictor variable...
