ORGANIZATION OF A GEOGRAPHIC INFORMATION SYSTEM (GIS) DATABASE ON NATURAL HAZARDS AND STRUCTURAL VULNERABILITY FOR THE HISTORIC CENTER OF SAN GIULIANO Dl PUGLIA (ITALY) AND THE CITY OF VALPARAISO (CHILE)

摘要

Remote sensing (RS) and geographic information systems (GIS) are powerful tools to create maps, scenarios, and inventories for habitats and heritage to manage hazard, vulnerability, and risk due to naturallanthropic disasters. In the framework of this huge investigation field, some research, susceptible to development, has been done. The first GIS nucleus, targeted on earthquake and joining architectonic/urban planning analyses with vulnerability evaluation, began in the framework of four master's theses, a cooperation between the ENEA (Italian Agency for New Technologies, Energy and the Environment) and Ferrara University. The work concerned San Giuliano di Puglia (hit by the 2002 earthquake) because a lot of material was available due to several activities performed there by ENEA experts. Architectonic/urban planning studies regarded the whole ancient core, while vulnerability analysis focused a specific inner sector. Another GIS activity grew in the MAR VASTO Project (centered on Valparaiso, Chile), managed by ENEA, with participation of ItalianlChilean partners and support of local stakeholders. The project stressed the following points: to evaluate the impact of main natural)'anthropic hazards; to provide architectonic/urban planning and vulnerability analyses for a pilot building stock in the historic area; to carry out surveys and vulnerability evaluations on monumental churches; and to suggest guidelines for future interventions.
