In the light of current developments in Information Communication Technologies, this paper presents three case studies of the usage of geo- information technologies concerning the management and recovery of historical built heritage. With reference to the experiences of the authors in Sardinia, Italy the first example reports on the impact of the Regional Spatial Data Infrastructure to the safeguard of historical built heritage in urban and regional landscape planning. The second example reports on the use of Geographic Information Systems in historical centres redevelopment. The third example deals with the development of a web-based knowledge base on the earth architectural heritage aimed at supporting its recovery and reuse. Some conclusive remarks outline the role of authoritative and volunteered sources of information in the domain of historical built heritage. Keywords: Geospatial technologies, web-GIS, built heritage, urban and regional landscape planning, earth architecture. 1 Introduction The interest of researchers and urban planners on information systems developments as a support for the protection and management of historic built heritage has been developed in Italy since early 1980s. It is worth mentioning early experiences such as the development of a data base for the historic centre of Pietrasanta [1] or for the historic centre of Cittadella [2]. The attention to this field of study was further enhanced in the following decade, reaching a high degree of maturity along with the Information and Communication Technology (ICT) evolution. In Europe at the end of the 1990s the work of HISTOCITY [3], a European research network that between 1997 and 2000 has promoted the exchange of knowledge on the use of Geographic Information Systems (GIS) to support sustainable historic centres re-development, have helped to clarify the relationship between the construction of digital archives of spatial data on historical settlements and their support on decision making for urban recovery. In the last decade, developments and the pervasive diffusion of Information Communication Technology (ICT), have enriched the architectural models of GIS,
