The existing topomaps do not identify normally more than 50% of the terracements present in an area; yet, such data are necessary for any consideration about recovery and even more for any project. So, this is a basic problem for terraced areas, that nowadays is becoming even more interesting thanks to the use of GIS cartography.
Looking at what have been presented in Goriska Brda, and also to other works I have seen in international congresses, the idea of building a GIS map of terraced areas is being recognized as a common and important step to promote terraced areas. Summarizing the working process (as done in the presentation by Varotto) can open the way to propose it to other Regional or State Governments, or even to EC, as a standard method, that can perhaps be applied to other peripheral areas.
Furthemore, the idea of classifying terraced areas (launched, I think, by Prof. Scaramellini from Univ. of Milan) is very stimulating and useful to synthetize the characters of an areas in a definition that represent its various different aspects (agricultural, historical, social). The discussion about the proposal done in Brda should be continued whenever possible to implement this classification.
I am trying to summarize here below what said in the work session in Genoa, to start a deeper discussion about the point that remained open.
This topic aims at developing the use of Geographic Information Systems (GIS) in mapping of terraced area. The first points the partners have agreed on is:
Use of aerial orto-photographs at scale 1:10000 as effective base for mapping
Necessity of surveys on the field for higher detail
The next point to be developed regards the addtional data (’fields’) linked to each terraced sub-area, that are needed to support activities of monitoring and analysis. A list of such data is in course of development by the project, to produce a base GIS structure for terraced areas.
All the guys that took part to the discussion in the afternoon in Genoa are invited to give their response to this summary.
