- Abstract
- The main target of the Sistan Project is the reconstruction of the prehistoric archaeological landscape, beginning from multispectral satellite data. In order to draw a new map (historical, cartographic and geological) of Southern Sistan, a TM image of Landsat 5 satellite was used, with a resolution of 28.5 mt per pixel, including 7 spectral bands. By comparing geological features with the position of archaeological sites in the prehistoric age, and processing this digital data, new information have been obtained and hypothesis proposed for the ancient population of the region. In particular, DTM (Digital Terrain Model) reconstruction, multispectral classification (raster data) and vector integration of data (archaeological sites, terraces, geomorphological features, contour levels), have allowed us to visualise a complex and dynamic model in 3 dimensions. For this aim virtual reality techniques (not immersive) have been used: on a workstation, the user can explore in 3D the landscape model in an interactive way, navigating through the digital data and choosing different perspectives and points of view. Moreover, it was also possible to process at the same time multidimensional information, such as the altimetrical model, unsupervised classification, natural spectral color, different spectral bands, vector data and so on.
