Earthquake-Oriented Spatial Modeling of Relational Coded Geographical Attributes

Abstract

The main goal of this study is to derive a digital ground quality map which is scaled, rectified, projected and database interactively by using contribution independent of amount through positional recoding and grading methodology. Within this target, the grading of ground quality and the effect assessment of residential areas were studied in terms of exposed to earthquake. Three-dimensional geographical modeling techniques were used in digital platform and attribute affects to ground quality were encoded in the ratio of their contribution to the outcome by mapping one by one. As a result, through the digital map, models were comparing with the data of the actual area, the influence risk of ground was graded and was spatial elaborated in terms of geographical attributes. For this purpose, based on case study, in the Eskisehir-Turkey region two districts were chosen and in an attempt to examined the regions ground quality, the results of the previous projects are compiled. As a layer, maps of all geographical parameter which were contributed to ground quality had been graded by using modeling techniques and re-mapped by encoding. As a result of this methodologic study, dynamical interactively digital risc map was obtained for check the actual situation of buildings in terms of earthquake effect.
