Evaluation Of Vulnerability On Turkish Coastal Provinces With Gis


                 •   All  data  was  converted  to  raster  data  through  Feature  to  Raster
                     process.
                 •   The resulting raster data was reclassified to be used in weighted
                     overlay analysis.
                 •   Thanks to the process done with Reclassify command, all complexity
                     in all the raster data set is eliminated, which allowed the reduction
                     of the data to a certain evaluation criteria.
                 •   After  the  classification  process,  the  Weighted  Overlay  analysis  is
                     implemented based on the data. During this process, each piece of
                     data was assigned a point depending on their level of effect. Thus,
                     the effect of each indicator on the analysis was observed.
                 •   As a result of all these processes, a map was created on costal cities
                     with high, medium and low vulnerability.
               For the vulnerability analysis, a data set was created based on the studies in this
            area. The data set on Table 1 is caterorized as physical, spatial, economic and social.
