- Abstract
- This paper concerns computer applications for the management of archaeological data through GIS software, as related to the 2008 excavation campaign at “Mura Bastia”, Onigo (Treviso), Italy. The approach allows for the correlation of data previously acquired with those collected more recently using newer technologies. The shift from the traditional way of drawing archaeological records to the new digital technique began during the excavation of 2007. All of the walls and the layers were documented using a total station and a digital camera (photo-mosaic method). The elaboration of raw data was obtained using Free and Open Source Software only (GRASS, E-FOTO, GIMP, OPENJUMP, gvSIG). All of the new information levels (bi-dimensional raster and vector layers) were connected with the digitized plan of the old excavation into a GIS project that became the final product of the whole work. 3D terrestrial laser scanning surveys, integrated with classical topography and digital photogrammetric methodologies, allowed us to extract an accurate and photorealistic digital model of the Onigo castle. Moreover, a partial 3D virtual anastylosis of the tower was completed thanks to the reallocation of two missing elements in their correct position.
