AbstractGeoHeritage-GIS (GH-GIS), a web site concerning Palermo Historic Centre monumental Heritage, developed within Project 7T7 Cluster C29, funded by MIUR, has been designed as a permanent interface between who studies the hazard factors interesting this area and a vast category of final users which operate to safeguard Palermo Monumental Heritage, a very precious common weal. These end-users will benefit from homogeneously collected, frequently improved and periodically updated data concerning soil properties, seismic effects and all of that can help to define the hazard exposition of each monument, having an important tool in establishing a scale of priorities for interventions and resource allocation.On start-up GH-GIS shows the geo-referred monumental database (MD) of Palermo upon a geo-referred map of Palermo historic centre, that can be manipulated using some of the standard GIS tools (e.g., zooming, panning, distance measurement, etc). The user can access to all information concerning a specific database element by directly clicking it upon the map, by digitizing monument name or by selecting it from the list of database elements. GH-GIS can provide monuments lists answering specific requirements imposed by user. The user may superimpose on this map the total dataset concerning Palermo Historic Centre worked out within the aforementioned Project 7T7 Cluster C29, which includes a high density stratigraphic-geotechnical database, the stratigraphic and lithotecnical sections database worked out, describing fundation soils of several MD elements, the accelerograms database of the September 2002 seismic sequence, recorded by eight temporary digital seismic stations, installed by INGV and Geology and Geodesy Department Palermo University, inside Palermo Historic Centre, the “AeDES” damage census database set up after the 6th September 2002 earthquake by Civil Protection Regional Department -Sicily. These different databases can be simultaneously displayed and queried, directly relating them to MD elements, making readily evident possible correlations. Specifically designed dialog boxes give access also to relational information, allowing to recognise:MD elements affected by hazard factors as soft foundation soils (alluvial deposits, recent sea deposits, man made filling), a superficial water table, etc.., MD elements affected by vulnerability factors, as presence of crypts, MD elements affected by both hazard and vulnerability factors.The several implemented functions make GH-GIS a very effective support tool to safeguard Palermo monuments.
