A conceptual model for 3D subsurface spatial data integration: the integrated information voxel (IIV)

To fully understand the characteristics of subsurface spatial objects and the relationships between them, the integrating multi-source data of geology is demanded. This is made possible to establish the 3D subsurface spatial data integration model: integrated information voxel (IIV), which is established on the basis of the analysis and recognition of the characteristics of subsurface spatial data. The partition of the IIV should be followed some criteria to construct the boundaries. The characteristics of the IIV and the simplified process for the multi-data integration based on IIV is introduced in this paper. As a concept model, some other key problems such as the weight of the boundary and the precision evaluation of the integration should be studied further.
