The aim of this paper is to show the methodological approach and the research so far undertaken regarding the building up of a GIS on cultural and environmental heritage in Tuscan coastal areas.
Coastal wetlands represent a peculiar and interesting ecosystem both in terms of environmental settings related to characteristic vegetation or faunal associations or in terms of historical and cultural heritage as evidence of a past land use and human activities related to that singular environment. In Tuscany the coastal wetlands are particularly interesting for their environmental and geomorphologic contexts that today appear degraded and stressed by pollution and urban and industrial expansion. Due to their particular conditions these zones have been selected as study areas with the aims of setting up a Geographical Information.
The phases of the research are as follows:

The methodology adopted in this work is based on the comparative analysis and integration of different sources of archaeological, historical and geographical information chosen for various kinds of scale and detail. Cartographic and documentary sources are found in Toscana and Emilia Romagna Archives. In particular we have gathered and used historical cartography from 15th to 19th centuries preserved in the National Archives of Tuscany and in others Historical Archives. The complex set of data taken into consideration are archived and related by means of a GIS. The comparability of information regarding past and present phenomena allows for the understanding of some transformation of the wetland and ex-wetland landscape focusing in particular on the land use changes.
