Historical maps (cabrei) and remote sensing technologies to understand landscape evolution (Bologna province, Italy). The purpose of this paper is the evaluation of the landscape transformations through almost four centuries by superimposing old maps, known as Cabrei, on current aerial images. These maps, drawn by land surveyors (between the XVI and XVIII century), included important crop and land use information as well as rural edifices, shafts and natural elements. After digital acquisition and smart cataloguing, the maps were georeferenced with a new two-stage technique, using the international UTM-WGS84 datum. With the use of GIS it is possible to discover the landscape invarians and to highlight the rural architecture: this is necessary to draw up territorial development plans that can valorize and preserve typicalities of the countryside.

Abstract

Historical maps (cabrei) and remote sensing technologies to understand landscape evolution (Bologna province, Italy). The purpose of this paper is the evaluation of the landscape transformations through almost four centuries by superimposing old maps, known as Cabrei, on current aerial images. These maps, drawn by land surveyors (between the XVI and XVIII century), included important crop and land use information as well as rural edifices, shafts and natural elements. After digital acquisition and smart cataloguing, the maps were georeferenced with a new two-stage technique, using the international UTM-WGS84 datum. With the use of GIS it is possible to discover the landscape invarians and to highlight the rural architecture: this is necessary to draw up territorial development plans that can valorize and preserve typicalities of the countryside. It is also possible to exploit these maps for historical research, the study of toponyms and the evolution of rural settlements.
