Le procedure per la realizzazione di modelli 3D di beni culturali ad alta risoluzione richiedono in genere sia fasi di rilievo impegnative sia operazioni di elaborazione ed editing dei dati spesso assai onerose dal punto di vista computazionale ed operativo. In particolare, il numero enormemente elevato di punti che deriva dalla fase di acquisizion...

The diffusion of the use of Geographical Information Systems in archaeology has considerably increased in recent years. This multiplicity of applications is due mainly to the growing interest of archaeologists in modern methodologies for the management of archaeological data, surveyed by topographic, photogrammetric and remote sensing techniques. G...
Conference Paper
A first topographic survey of Grotte della Gurfa was carried out by Prof. Marescalchi in 1995. In 2009 a second survey was executed with the use of more recent techniques (total station, laser scanning, GPS). The comparison between the two surveys provides valuable indications to assess the evolution of the Geomatics techniques in these fifteen yea...
Conference Paper
The advance of information technology has enabled in recent years new fruition scenarios for cultural heritage sites. Multidisciplinary approaches integrate survey techniques with multimodal interfaces to allow enhanced fruition for larger group of users. In this paper we propose a multimodal interface to a virtual representation of a medieval ceil...

Telephone and radio communications are based on the electromagnetic wave motion in the ether, that may cause electromagnetic pollution. Italian laws provide surveying on electromagnetic emissions, standing on the point of interest with certified instruments for six minutes. Measures carried out according to this procedure are so long and expensive...

The paper describes one of the first outcomes of an Italian national research Project on inertial positioning in photogrammetry. The focus of the paper is on the quality which is attainable from direct photogrammetry in an industrial production context. Even if GPS/IMU -aided photogrammetry is used rather widely, it is still useful to perform rigor...

The paper describes the first results of a study, supported by an Italian research project "Integrated Inertial Positioning Systems in Aerial Photogrammetry" on the potential use of these techniques for production of digital large scale orthophotos. The study has been done with aerial photographs collected from two different flights executed in Sic...

This paper describes the first results of a study, carried out within the national research program "Cofin2001", on the potential use of high resolution satellite images for making digital orthophotos at a scale of 1:5000 and 1:10,000. Particularly, images from IKONOS II and QuickBird of four different types of areas were employed: the first area i...

Aerial photos, both in colour and in black and white, have always been very important tools in archaeological surveys. Sensors, called hyperspectral, were available on the market for some years: they are able to expand the research beyond the visible area of the electromagnetic spectrum as far as the thermal infrared too. The use of these sensors,...

Archaeology is one of the sectors that can benefit by new surveying techniques (i.e. those ones related to the use of GPS) for the representation and the management of an archaeological site. Another aspect of the archaeological sector that can take advantage from the use of both GPS and GIS instruments is guided visits of archaeological sites. Tod...

This paper proposes a study on the virtual reconstruction of temple B in Selinunte. It is the smallest of Selinunte's temples yet, despite its size, it has been the subject of great interest and debate by scholars since its discovery in 1823. The studies carried out throughout the XIX century and the first half of the XX century provided different...
