Implementación de la fotogrametría para la salvaguarda del patrimonio paleontológico canario

Abstract

The fossil record of the Canary Islands has a great importance and outstanding nature due to its preservation in a context of oceanic and active volcanic islands. Along the fact that some of the paleontological sites are located near the coast, the difficulty of their preservation is increased. In this work we present the use of the 3D digitalization technique called photogrammetry for the first time in the Canary Islands. The chosen fossil site was Igueste de San Andrés, located inside the Anaga Biosphere Reserve (Tenerife, Canary Islands), which was recently proposed to become a site of Cultural Interest (Palaentological Zone). This fossil site was selected because of its complexity to test conventional photogrammetry usefulness. As a result, it was obtained that in cases of extensive and complex coastal deposits such as the one studied, models may be improved by using drones. Likewise, it is proposed the creation of a digital catalogue as a monitoring, preservation and dissemination tool for the canarian paleontological heritage
