Abstract
In this study, an algorithm that was developed for three-dimensional volumetric visualization of numerical data sets obtained from geophysical measurements by using orthogonal slices is presented. This algorithm was used for the presentation of the response of shallow synthetic models using direct current resistivity (DCR) method. Synthetic apparent resistivities were processed by two-dimensional inversion scheme and inverse model resistivity sections were obtained. The results were presented by three-dimensional volumetric sections produced from twodimensional inverse model resistivity sections of parallel profiles, and horizontal and vertical continuities of the anomalies of model bodies were easily demonstrated on a single figure. Additionally, the developed algorithm was used to evaluate DCR data sets which were obtained from various investigations in different areas, and the resultant volumetric images contributing to the interpretations were presented

Abstract
Bu çalışmada, jeofizik ölçümlerden elde edilen sayısal verilerin ortogonal dilimler kullanarak üç-boyutlu hacimsel görüntülenebilmesi için geliştirilen basit bir algoritma sunulmuştur. Bu algoritma doğru akım özdirenç (DAÖ) yöntemi ile sığ derinlikte gömülü kuramsal modellerin tepkisini sunmak için kullanılmıştır. Kuramsal görünür özdirenç verileri iki-boyutlu ters çözüm tekniğiyle değerlendirilmiş ve yer elektrik kesitler elde edilmiştir. Sonuçlar, birbirlerinden bağımsız paralel hatlara ait iki-boyutlu yer elektrik kesitlerin bir araya getirilmesi ile oluşturulan üç-boyutlu hacimsel görünümlerle sunulmuş ve model yapılara ait belirtilerin hem düşey hem de yanal yöndeki sürekliliklerinin tek bir şekil üzerinde kolaylıkla izlenebilmesi sağlanmıştır. Ayrıca, geliştirilen algoritma farklı ortamlarda farklı problemler için gerçekleştirilmiş DAÖ çalışmalarında elde edilen verilerin değerlendirilmesinde de kullanılmış ve yorumlamaya katkı sağlayan bu hacimsel görüntüler sunulmuştur.
