Here we present an inventory of virtual outcrop models from the Cantabrian Zone and Asturian Basin, North-Northwest Iberian Peninsula, and the procedure employed to obtain the data, construct the models and interpret them geologically. There is no doubt that the development of digital techniques in recent times has facilitated these tasks. The first steps to study natural structures are data collection, their representation and their geological interpretation. The 3-D visualization and cross sections help in the understanding of the geometrical relationship between the different geologic features, allowing a reexamination of the tectonic history of the area during the late Mesozoic. The case study chosen to illustrate the method is the Beirut watershed (Lebanon), an area with relatively simple geology. To illustrate how a 3-D geologic map can be computed, we explain the steps taken to build a dummy model with simple faulting and depositional sequencing.

The major advantage of using such technology is that it provides the user with a way to quantify geology. It is based on a modeling algorithm that only, uses surfaces calculated from scattered data points and that intersects them following a series of geologically sound rules. The method is innovative in that it only uses surface information based on the combination of a standard geologic map, a satellite image, and a digital elevation model. We present a way to produce mathematically and geometrically correct three-dimensional (3-D) geologic maps consisting of the volume and shape of all geologic features of a given area.

Recent discoveries in earth sciences are mostly related to technologies allowing graphical representations of volumes.
