Abstract

Simple photogrammetric data capture methods and equipment are able to measure accurate dense point clouds and detailed high geometric quality Digital Surface Models (DSMs) can be generated out of them. These products are frequently applied to the recording of rock art. However, their potential is not just limited to documentation and their use can be extended to perform analytic tasks. This paper describes the authors’ first experiments in the morphometric analysis of an engraved surface (an epigraph), based on a DSM generated from photogrammetric data. Slope and curvature models were derived from this DSM and used to identify and extract some structural features of the carvings, much in the same way as topographic landscape features can be identified on a terrain DEM.
