Short summary

Any 3-D geological model is subject to uncertainty. We applied the concept of information entropy in order to visualize and quantify changes in uncertainty between geological models based on different types of geological input data. Furthermore, we propose two measures, the city-block and the Jaccard distance, to directly compare dissimilarities between models. The presented approach helps to locate areas of uncertainty within the model domain and quantify model improvements due to added data.
