La piattaforma GIS dello scavo di Poggio Imperiale a Poggibonsi. Dalla creazione del modello dei dati alla loro lettura

This paper concerns the specific experience of our Laboratory in managing archaeological excavations on a GIS platform; the development process of our solution started five years ago and brought us, through successive stages of refinement, to an efficient data model. The basic idea was to reproduce on a graphic level the exact situation we find in the field. We therefore organised our objects according to an overall composite plan representing all the excavated layers, as well as the necessary landscape features, related only in spatial terms; detailed alphanumerical data and interpreted information were derived from the DBMS using specific identifiers. The objects were organised in views according to different parameters and queries; examples of views we created involved the surrounding landscape (e.g. with archaeological surveys, land cover and use, geology, etc.), preliminary investigations (with analytical surveys and crop-marks detection), and stratigraphical data (with a composite plan of all layers as well as analytical views based on chronological aspects, excavated structures, etc.)
