La Lluera I Cave (San Juan De Priorio, Oviedo, Asturias, Spain): Art and GIS of the More Figurative Areas or “Niche Areas” of a Sanctuary

Since the beginning of the rock art until today, the study of prehistoric art has been done with different tools (drawings, photos, tracings, etc.). The study of the engravings in La Lluera I cave is a good example. Today, everything can be integrated into the appropriate tool: GIS. The engravings are the peculiarity to destroy a portion of the surface rock leaving a hole made with an object or even by hand. This hollow drawn in 3D is the sketch. It is known as sketch to the delineation that is formed with the design or plant of anything. The present study focuses on the more figurative areas or "zones niche" the cave of Lluera I: the niche (379 sketches), the entry´s horse (22 sketches) and the bison´s area (111 sketches). The creation of a 3D GIS of the sketches has been, thanks to the technical advantages posed by GIS, a revision to the art of these three areas, and a face wink to the future: GIS, thanks to augmented reality and interactivity, may be the best didactic support for a virtual visit.
