Multi-scale mapping of a habitat on a rugged site: Silla del Papa (Spain)

As part of the ANR Archeostraits program, a mapping of the archaeological remains of the site of Silla del Papa (Southern Spain) was undertaken. It is made complex by a rugged topography, with strong unevenness and a ground covered by persistent vegetation. In addition, Late Iron Age buildings are embedded in rock walls at several levels, making traditional architectural analysis ineffective with 2D planimetry. Multi-scale 3D analysis, from the surrounding territory to the excavation of a house, requires an adaptation of 3D acquisition tools. For this purpose, we have used three technologies developed in the Traces laboratory to generate dense point clouds.
