This study attempts to integrate geophysical data with other spatial data using Geographic Information Systems (GIS). The study is carried out in a part of Galatean Volcanic Province, north of Ankara. Gravity, magnetic, topographic, rock type and volcanic eruption center data are the data layers used in the study. All data layers are converted to raster format with a grid spacing of 100 m.
The first step in the analysis is the pair-wise analyses of all data layers. For the geophysical data, different layers for the depths of 1 to 5 km are generated. All paired analyses indicate that geophysical and other data sets are correlative among each other but show no relationship for any two layers from different sets.
In the second step of the analyses, two geophysical data are combined and overlaid with layers from the other set. These analyses indicate that relationship between geophysical data with other spatial data becomes more evident and that the geophysical data can be successfully integrated with other data sets. Accuracy of the results is highly dependent on the accuracy of both data sets. Analyses have shown GIS can contribute to the investigation of spatial distribution of buried planar structures using geophysical data.
