    Investigating the climate change impacts on the water resources of the konya closed basin area (Turkey) using satellite remote sensing data
    (Springer New York, 2013) Ekercin S.; Sertel E.; Dadaser-Celik F.; Durduran S.
    This chapter presents the pre-results from an ongoing study that mainly focuses on the use of remote sensing data to investigate the climate change effects on water resources in the Konya Closed Basin Area (KCBA), Turkey. In this study, multitemporal Landsat images along with climatic data were used to explore the dimension of drought effects on water lands and lakes located in the basin area. Image processing procedure includes both normalized difference vegetation index (NDVI) image interpretation and pre-processing stages (geometric and atmospheric correction). Our results suggest that in addition to socioeconomic profits of the use of groundwater for agricultural purposes, its effects on the ecological balance and water reserves in the KCBA should be analyzed in detail. Also, management strategies and plans should be developed to protect and/or rehabilitate current conditions in terms of drought in the KCBA. Furthermore, the region should regularly be monitored by up-to-date remote sensing data (at least annually) for better management of the water resources in the basin. © Springer Science+Business Media New York 2013.

    Kelenderis uncovered
    (2005) Durduran S.; Erdi A.
    Today, Geographic Information Systems (GIS) are accepted as useful multi-disciplinary tools for archaeological planning, estimating, mapping and visualisation, including the creation of three-dimensional Digital Terrain Models (DTMs). While maps have traditionally been emplo yed to plot the location of archaelogical 'finds' and to trace the layout of ancient settlements, the advent of GIS has allowed much deeper analysis of the linkage between geography and historical events. This has certainly been the ca se at Kelenderis and where the compilation of digital mapping and the creation of a Digital Elevation Model (DEM) has yielded much useful information concerning the city's structure and antiquity.

    Renewal and completion problems in geographical databases in Turkey and a proposal model
    (Ubiquity Press Ltd, 2007) Erdi A.; Durduran S.; Yildirmiş Ç.
    Defence, security, public works, and many other branches of government require small-scale, current geographical databases. With this aim, small-scale geographical databases in Turkey were produced in the past and are still in use today. There are, however, problems in using the available geographical databases. These problems informing, sharing, updating, and meeting requirements necessitate the reconfiguration of the present system. Classical approaches are preferred when updating the present geographical databases. Many errors and difficulties in recording new objects have occurred in the field, in scanning and collecting data from related institutions, and in recording and controlling nonstandard completion data. Thus it is difficult to achieve the desired high quality data with the present method. In this study, we introduce and discuss updating and completing small-scale maps of geographical bases. The Geographical Information System formation studies in Turkey are summarized, and a model is proposed for the formation, updating, and completion of systems of small-scale maps of significant databases.
