Photogrammetric processing and fruition of products in open-source environment applied to the case study of the archaeological park of pompeii

Abstract. The paper presents the geomatic survey campaign carried out in the Domus V of Pompeii Archaeological site, the photogrammetric processing of the collected images and the following fruition of the deriving products deploying open-source software. Among all the produced results, the orthophotos of the vertical walls of one of the Domus V rooms are made available through a “master/slave” GIS environment, where each orthophoto is uploaded in a “slave” project whose visualization is triggered by querying the corresponding geometry representing the wall in the “master” project. This strategy allows to include the display of the third dimension, i.e., the altimetric one, within a traditional GIS environment, so to constitute a 3D GIS representation. This is particularly useful to realize a catalogue of all the archaeological site in the future to be viewed, queried and exploited also by non-specialists in geomatics or archaeology fields of knowledge.
