[Termes IGN] SuèdeRésumé : (auteur) Signatory countries to the United Nations Framework Convention on Climate Change (UNFCCC) and its supplementary Kyoto Protocol (KP) are obliged to report greenhouse gas emissions and removals. Changes in the carbon stock of living biomass should be reported using either the default or stock change methods of the Intergovernmental Panel on Climate Change (IPCC) under the Land Use, Land-Use Change and Forestry sector. Traditionally, volume estimates are used as a forestry measures. Changes in living biomass may be assessed by first estimating the change in the volume of stem wood and then converting this volume to whole tree biomass using biomass expansion factors (BEFs). However, this conversion is often non-trivial because the proportion of stem wood increases with tree size at the expense of branches, foliage, stump and roots. Therefore, BEFs typically vary over time and their use may result in biased estimates. The objective of this study was to evaluate differences between biomass estimates obtained using biomass equations and BEFs with particular focus on uncertainty analysis. Assuming that the development of tree fractions in different ways can be handled by individual biomass equations, BEFs for standing stock were shown to overestimate the biomass sink capacity (Sweden). Although estimates for BEFs derived for changes in stock were found to be unbiased, the estimated BEFs varied substantially over time (0.85–1.22 ton CO2/m3). However, to some extent this variation may be due to random sampling errors rather than actual changes. The highest accuracy was obtained for estimates based on biomass equations for different tree fractions, applied to data from the Swedish National Forest Inventory using a permanent sample design (estimated change in stock 1990–2005: 420 million tons CO2, with a standard error amounting to 26.7 million tons CO2) Many countries have adopted such a design combined with the stock change method for reporting carbon stock changes under the UNFCCC/KP.

[Termes IGN] tsunamiRésumé : (Auteur) The following research aims to enhance and spread the capacity of assessing risk due to landslide-generated tsunamis by fostering the use of a GIS (Geographic Information System), and in this particular instance, an Open Source GIS (where “Open Source” can be loosely defined as freely available source code). For this purpose, we tested a procedure to be spatially implemented in the Open Source GRASS GIS through developing a module named r.impact.tsunami that simulates landslide-generated tsunami. In this article we present its application in a case study performed on Como Lake (Lago di Como) in northern Italy. The review of the results identified sources of uncertainties while the model sensitivity outlined the influence of the parameters governing the model. Moreover, in order to verify the model validity, we implemented a new module (r.swe), that simulates the tsunami propagation and run-up with the shallow water equations, and compared the results. Notwithstanding non-negligible differences, the two models produced results of the same magnitude; this confirmed the validity of both models, although a rigorous validation of the models could not be performed due to the lack of observed data.

[Termes IGN] PostgreSQLRésumé : (Auteur) The Wales Institute of Socio-Economic Research, Data and Methods (WISERD) is an interdisciplinary, cross-institutional academic research group based in Wales, UK. One of the key objectives of WISERD is to develop a spatial framework that enhances a researcher's ability to discover socio-economic research data relating to Wales with the aim of encouraging collaborative research and re-use of existing data. This article describes the development of an online geoportal designed to meet this objective. Using free and open-source software (FOSS) components and services, a range of software tools has been developed to capture standards-compliant metadata for a variety of data sources. The geoportal is unique in that, in our review of over 120 geoportals worldwide, we have not previously encountered a geoportal dedicated to supporting quantitative and qualitative social science academic and policy research. A particularly innovative aspect of the geoportal has involved the building of a rich meta-database of government surveys, geo-referenced semantically-tagged qualitative data (generated from primary research), ‘grey’ data (e.g. from transcripts, journal publications, books, PhD theses) and Government administrative data. This article describes the challenges faced during the development of the WISERD Geoportal which can be accessed via http://www.wiserd.ac.uk/geoportal/.

[Termes IGN] WebSIGRésumé : (Auteur) In the State Archive of Como, Northern Italy, about 15,000 historical maps belonging to different national cadastral productions are preserved. The Web C.A.R.T.E. project was started to enhance the accessibility of this valuable cartographic heritage using FOSS (Free and Open Source Software) technologies. The system, which implements specific web geoservices for cataloguing and visualization, should assist the State Archive of Como in the digital management of its cartographic resources and related information. After the high-resolution digitization step, maps undergo a georeferencing operation. A special statistical procedure for choosing the best mathematical model was developed, verifying also strengths and weaknesses of georeferencing with a common free and Open Source GIS. Next, metadata consistent with current Italian standards were added to the georeferenced maps using an ad hoc localized version of GeoNetwork Opensource (recently provided as the official Italian version of the software). A dedicated WebGIS system was built for publishing the georeferenced cadastral maps. This system is capable of navigating large raster data in a georeferenced framework and easily retrieving their metadata. The WebGIS system for the State Archive of Como is an important contribution for the preservation of the original historical paper maps and also a great modernization and simplification of the end user's access to this archive.
