A quattro mesi dalla conclusione dell’indagine, è’ on-line tutta la documentazione della campagna di scavo 2011-2012 in modalità open data, rilasciata con licenza CCBY. Due volumi e un insieme di dataset scaricabili gratuitamente.
Martedì 23 ottobre, alle ore 16,00 presso l’aula C del Dipartimento di Scienze della Terra – Università di Pisa (Via Santa Maria 53, Pisa)
il Prof. Neil Roberts dell’Università di Plymouth terrà un seminario dal titolo:
“Holocene climate change in the Mediterranean region”
School of Geography, Earth and Environmental Sciences Plymouth University Plymouth PL4 8AA, UK
Proxy palaeoclimatic methods provide the main source of empirical data by which Mediterranean climate change can be reconstructed for the period since the end of the last Ice Age. They enable testing of numerical simulations of regional climate under boundary conditions significantly different from the present-day, including changes in radiative forcing, ice volume and atmospheric greenhouse gas concentrations. In this talk, I will assess the spatial and temporal pattern of past climate change across the Mediterranean region for four different time periods during the last 15 ka. This offers insights into the mechanisms that have controlled long-term shifts in atmospheric circulation and climate dynamics in this region.
Neil Roberts is Professor of Physical Geography at Plymouth University, UK.
His research emphasizes past climatic and environmental change since the time of the last glacial maximum, specifically derived from lake-sediment archives. He is author of the key text, the Holocene, and is an editor of the journal Quaternary Science Reviews. Professor Roberts served on the National Academies Committee on Surface Temperature Reconstructions for the Past 2,000 Years, set up at the request of the US Congress. In 2007 he was visiting Blaustein research fellow at Stanford University.
Monitoraggio sugli open data in Italia nella pubblica amministrazione (aggiornamento settembre 2012):
The Archaeoscapes strategic project aims to address the study and development of a semi-automatic (in the form of a demonstrator) for the production of probability maps of the presence of significant archaeological sites based on the joint processing of multi-sensor data sources of different nature. This system will be able to store, compare and manipulate data from these sources in a completely transparent way to the user. The demonstrator will show a set of layers that will provide information on historical data, physical characteristics of the area of interest and results of signal and image processing for cataloging and production of maps aimed at the so-called “predictive archeology.” The dataset will be converted and processed in the same Geographical Reference System.
Dutch archaeology has experienced profound changes in recent years. This has led to an increasing use of archaeological predictive modelling, a technique that uses information about the location of known early human settlements to predict where additional settlements may have been located. Case Studies in Archaeological Predictive Modelling is the product of a decade of work by Philip Verhagen as a specialist in geographical information systems at RAAP Archeologisch Adviesbureau BV, one of the leading organizations in the field; the case studies presented here provide an overview of the field and point to potential future areas of research.
The project proposal is the prediction model based on GIS for the prediction in the field of archeology. It is an interdisciplinary project in which these methods were used:
- Iteration number (prediction model outputs are compared with the results of subsequent research in the field and process prediction is restarted with the correct inputs)
- A multidisciplinary approach – cooperation experts from different disciplines (archeology, geodesy and cartography, computer science)
- Fuzzy model (GIS functions with blurred interface)
- Spatial analysis based on two-valued or fuzzy logic
- Expert system – making use of the expert’s skills in the evaluation and interpretation of partial and final results
CAA is an international organisation bringing together archaeologists, mathematics and computer scientists. Its aims are to encourage communication between these disciplines, to provide a survey of present work in the field and to stimulate discussion and future progress.
