- Abstract
- This paper illustrates preliminary results of the research project “An inventory of the Terramare in the central Po plain: physiographic context, stratigraphic and structural characteristics, state of preservation”, part of the Cultural Heritage Special Project, promoted by Italian National Research Council. The project involves GIS and remote sensing applications in order to integrate different 2D-3D georeferenced data (sites, excavations, surveys, landscape and territorial data) such as: a) raster data (aerial photographs of different periods starting from 1950, regional cartography, DEM); b) vector data (cartography, thematic layers, archaeological sites, etc.); c) a DEM created by cartographic contour lines and using a total laser station on the ground; d) alphanumeric data (excavation databases, territorial databases). The methodological approach has been to represent and analyse archaeological data from micro-scale (intra-site) to macro-scale (inter-sites), in particular exploring the perspectives of 3D GIS visualisations. Attention was therefore concentrated on the topographical reconstruction of microrelief in relation with the aerial photos (of different periods) used as textures, geomorphological features and archaeological data. We can define this kind of processing as a visualisation of an invisible landscape, as much more information can be retrieved from the terrain than using traditional techniques (aerial photo-interpretation, survey, etc.); in many cases this is very useful in order to help plan an excavation. Regarding the acquisition and processing of multi-temporal, multi-layer and multi-dimensional data, this research deals with a large-scale detailed study of the data collected by topography, but enhanced by surveys and acquisition of data on the ground. In fact one of the main tasks of our project is the creation of detailed models on the basis of the microrelief.
