GIS a tool for 20th Century Architecture. From the territory to the building scale

Management, organization, and dissemination of data represent today one of the main topics of heritage protection and enhancement. Through four case studies, this contribution describes the use of GIS (Geographic Information System) applied to 20th century architecture, as a tool for critical analysis of data and their possible use for the design phase. The examination of the case studies highlights opportunities and limits of a peculiar use of GIS in the field of 20th century architecture, taking into consideration its specific features. Investigations developed at territorial, urban and building scale demonstrate GIS strengths and weaknesses for the improvement of projects on existing buildings.
