This paper is based on an interactive three-dimensional (3D) visualization of two-dimensional (2D) ground penetrating radar (GPR) data and their integration with electromagnetic induction (EMI) using EM-61 data in a 3D volume. This method was used to locate and identify near-surface buried old industrial remains with shape, depth and type (metallic/non-metallic) in a brownfield site. The aim of the study is to illustrate a new approach to integrating two data sets in a 3D image for monitoring and interpretation of buried remains, and this paper methodically indicates the appropriate amplitude-colour and opacity function constructions to activate buried remains in a transparent 3D view. The results showed that the interactive interpretation of the integrated 3D visualization was done using generated transparent 3D sub-blocks of the GPR data set that highlighted individual anomalies in true locations. Colour assignments and formulating of opacity of the data sets were the keys to the integrated 3D visualization and interpretation. This new visualization provided an optimum visual comparison and an interpretation of the complex data sets to identify and differentiate the metallic and non-metallic remains and to control the true interpretation on exact locations with depth. Therefore, the integrated 3D visualization of two data sets allowed more successful identification of the buried remains.
