The aim of the TILES project is to develop an advanced decision support system that can aid in the sustainable extraction of offshore sand in the North Sea for coastal maintenance and industrial use. To obtain this, tools that link 3D geological models, knowledge and concepts to numerical environmental impact models are required in order to quantify natural and man-made changes. The main contribution of DDCM is the extraction of knowledge from a 3D voxel model through an advanced multi-criteria decision making platform.
