A method of data structuring for the study of diffusion processes of raw materials and manufactured objects
2017
International audience; Workgroup 3 of the ArchaeDyn II programme aims at studying the diffusion systems of products in ancient times. In order to be able to structure data in GIS in an appropriate way, we propose to go through three levels of modelling: the first one aims at gathering together the different components of the diffusion systems taking into account their interactions; the second corresponds to a conceptual data model created with the help of the HBDS method, that will, as we get to the third stage, lead to the creation of a "three-dimensional" geodatabase. Here we point out the fact that the approach through the simple notion of “site” is not sufficient to study the products’…
Suoli d'Italia: minacce, stato ed efficacia delle risposte
2011
La degradazione del suolo è uno degli aspetti più rilevanti del cambiamento globale e la vulnerabilità dei terreni italiani ai processi di degradazione è certamente superiore ad altri paesi europei, a causa delle caratteristiche specifiche e dell’ alta variabilità delle condizioni ambientali.Oltre alle cause naturali, la degradazione del suolo è spesso causata dall'effetto delle attività umane ed in particolare all'utilizzazione delle terre non corretta. Le informazioni memorizzate nella base di dati nazionale del suolo sono state usate per un primo controllo della qualità dei suoli italiani e degli effetti delle politiche gestionali. La banca dati è costituita da un database, contenente in…
Promoting Research and Landscape Experience in the Management of the Archaeological Networks. A Project-Valuation Experiment in Italy
2020
Archaeological sites are part of the history and identity of a community playing a strategic role on the different scales of the cultural and economic common life. Whereas on the one end the most famous archaeological sites attract huge flows of tourists and investment, on the other hand, many minor archaeological sites remain almost ignored and neglected. This study proposes a project-evaluation approach devoted to the &ldquo
Theoretical space-time modelling of the diffusion of raw materials and manufactured objects
2013
International audience; Workgroup 3 of ArchaeDyn II programme focuses its study on the diffusion systems of ancient products. In order to be able to structure data in GIS in an appropriate way, we propose a general theoretical modelling integrating the different components of the diffusion systems, and identifying their interactions and the factors affecting the location of products and their transfers. Three dimensions are considered: the Time, the Space and the Function of places. A product's pathway can be apprehended efficiently by distinguishing spatial entities as well as functional entities. This modelling highlights the fact that the approach through the simple notion of "site" is n…
The soil map of Italy: a hierarchy of geodatabases, from soil regions to sub-systems
2014
This paper is aimed at showing the organization of the national soil information system managed by the Agriculture Research Council of Italy (Soil Information System of Italy, SISI). The available soil geodatabases for the whole of Italy are those of the soil regions (1:5,000,000), subregions (1:1,000,000), and systems (1:500,000), while the soil subsystems geodatabase (1:250,000) is available for most part of Italy.
