Spatial analysis of metal finds from Vetricella

  By

The creation of a GIS analysis environment for the study of the archaeological finds from the site Vetricella is aimed at producing new information by integrating spatial to alphanumeric data. The position of the finds was documented with the aid of the total station that produced a cloud of points representing their location in the stratigraphic context (Fig.). The alphanumeric data derives from the classification and study of the metal finds recovered over the course of the excavation campaigns conducted… Continue reading

Documentation of Vetricella site with digital photogrammetry

  By

The documentation of the archaeological excavation in the site of Vetricella is made entirely with digital photogrammetry. This video, presented by the nEU-Med project team during the BRIGHT 2018 event, summarizes the various phases of acquisition, processing on the field and examples of use as support for the management and interpretation of the excavation. The same technique can also be applied to the study of finds as a basis for reconstructive hypotheses.   Continue reading

3D documentation of archaeological small finds

  By

For the “nEu-Med day in Maremma” held the 31st of October 2018 in Scarlino, a spear head found during the archaeological campaign 2017 at Vetricella was documented using the photogrammetric technique, and on this basis two reconstructive hypotheses were modelled. This work was aimed at presenting to the public, the kind of activities that the team conducts on the informatic side and as 3D documentation, that, as presented in other articles on this site, is applied on the stratigraphy in… Continue reading

Vetricella from above: documentation with the drone

  By ,

In the last weeks of the third archaeological campaign at Vetricella, an UAV aircraft was introduced to support the documentation of the site. The aim of the flights was to acquire several sets of images for the processing of three-dimensional models with 3D photogrammetry and to shoot videos which will be used for the dissemination of the  ERC nEU-Med project. The drone used in this video is “DJI Spark”, a 300gr aircraft which mounts an integrated camera of 12 Mpx… Continue reading

CONTRIBUTION OF THE 3D DOCUMENTATION TO THE STUDY OF THE VETRICELLA SITE

  By

The 3D documentation carried out at the Vetricella site (Scarlino,GR) has reached its final stage. All the models are elaborated and georeferenced, and then imported into a GIS with a 3D visualization platform. This system allows the researchers to join the spatial data and alphanumeric contents, recorded on field in a context sheet and then stored in a database. Moreover it is possible to navigate and expore the 3D models through queries applied to the attributes of the objects. The… Continue reading

3D documentation procedure at the excavations of Vetricella and Carlappiano

  By ,

3D documentation procedure atthe excavations of Vetricella and Carlappiano, in the frame of the nEU-Med project. Highlight the context’s boundary. Placement of four markers around the context for the georeferentiation of the 3D model. Besides the four markers, with the total station several additional points are measured along the boundary. These points create a path for detecting the context’s boundary directly onto the 3D model. This step is fundamental for keeping a reliable detection of the boundaries inside the virtual… Continue reading

UAV flight for the survey at Vetricella and Carlappiano

  By ,

Tuesday 25th October the UAV flight, by ATS srl, has taken place for the 3D recording of Carlappiano (Piombino) and Vetricella(Scarlino) (Fig.1-2). 3D photogrammetry from UAV flight produces a 3D model of the entire excavation area, a fundamental support for performing spatial analysis, measuraments and to extract orthophotos and cross section (Fig.3-4).

3D documentation at Carlappiano and Vetricella

  By ,

At the excavations of Vetricella (Scarlino) and Carlappiano (Piombino) an Image-based 3D modelling technique is used for the documentation of the entire stratigraphy. We decided to use the 3D model as the main form of documentation for its high precision in recording the geometry and the colours of the contexts. 3D models obtained during the excavation are gathered into a 3D GIS platform, where the stratigraphy is reconstructed, managed and analysed in three dimensions (Fig.1). For each context the following… Continue reading
