QuantumGIS per la gestione dei dati dalla survey 2013 a Helawa nella piana di Erbil, Kurdistan, Iraq

The 2013 season of fieldwork of the Italian Archaeological Expedition in the Helawa/ Aliawa Area (MAIPE-Missione Archeologica Italiana nella Piana di Erbil, Kurdistan) was con- ducted by the University IULM of Milan, with the cooperation of IBAM-CNR of Lecce and the Sapienza University of Rome. The investigation focused on a small part of the South-Western Erbil plain and included two main mounds, Helawa (South) and Aliawa (North). A complete topographic plan was created starting from the measurements taken with differential GPS (for DEM and GIS elaboration). The collection of materials on the surface enabled us to make a preliminary assessment of the main periods of occupation at the site, spanning from the Late Neolithic (Halaf and Ubaid periods, 6th millennium BC) to the Middle Assyrian period (13th-12th century BC). The project of acquisition of topographic and archaeological records from the intensive survey conducted on the site involved the use of open source tools. All data were organized in a GIS system based on QuantumGIS and metadata are now stored in a PostgreSQL/PostGIS database, allowing for the subsequent phases of mapping elaboration. The topographic work produced a complete archaeological space-map, with distribution of materials on the surface, sections of the site, a digital elevation model and all the data collected during the survey entered in a webGIS. This paper illustrates the state-of-the-art of this GIS project, and introduces future developments like the web data-entry interface written in PHP, and the webGIS based on GoServer and GeoExplorer.
