[Termes IGN] modèle numérique de surfaceRésumé : (Auteur) Terrain is a surface phenomenon that is measured, modelled, and mapped. However, it is continuously variable and must be simulated by points or mathematical equations that are inherently approximations. The error induced by digitally represented terrain can propagate to surface derivatives and geographical information science (GIS) applications where topography is considered. This can lead to uncertainty in model predictions and the use of data that are unfit for the application to which they are intended. This article outlines the problem of uncertainty in terrain representation and demonstrates the consequences for volcanic mudflow modelling. The response of a simple least-cost single flow algorithm to input parameters was investigated in order to assess output variation from the different sources of input variation. Elevation error was modelled with a probability density function (PDF) and propagated through stochastic simulation (Monte Carlo). Such combined uncertainty and sensitivity analyses enabled a qualitative judgement of the relative significance of elevation error on the flow model prediction. Different methods for terrain model construction were considered and show that supplementing global positioning system (GPS) measurements with information from field notes and reconnaissance photographs greatly improved the model performance and reduced the uncertainty. It is concluded that in terms of validity of model results, there is no substitute for constructing an elevation model that is informed by the terrain.

[Termes IGN] utilisation du solRésumé : (Auteur) Landscapes that we see today will change in the future. Scenarios are used as a method for dealing with uncertainties in change and to provide plausible descriptions of our future world. A number of projects have utilised scenarios and a modelling-based approach to quantitatively investigate land use change at the national/regional-scale using a GIS. However, the coarse-scale of such land use data can render outputs inapplicable within local, often environmentally sensitive, landscapes. Improving data resolution allows us to investigate alternative potential futures at greater detail thereby providing vital input into policy and future decision-making. It may also facilitate localised studies of habitat fragmentation connectivity and visualisation. This paper utilises scenarios and regional-scale land use change data to facilitate a GIS-based model of land use change within a sensitive wetland environment. Land use change data from the RegIS project is localised to the study area in Broadland, UK. Areal totals, from the land use change data, are replicated within 0.01% of areal totals prescribed, enabling very spatially detailed land use maps to be developed. This work represents a locally explicit realisation of coarser regional-scale land use change data using an integrated GIS-Multi-Criteria Decision Analysis (GIS-MCDA) methodology.

[Termes IGN] transport de matières dangereusesRésumé : (Auteur) The transport phase is an often neglected element in the risk assessment of non-nuclear hazardous waste life cycles. Data on special and hazardous waste movements originally collected by the Greater London Council during the 1980s give detailed information about waste consignments from cradle to grave, including UK grid references for waste producer and disposal sites, total tonnage and hazard category. Aqueous special wastes were chosen as a case study in wich a geographic information system was used to model the routing of waste consignments. Deficiencies in the consignment records required several assumptions to be made and various scenarios explored. Roads identified as likely to see passage of these waste materials, together with the estimated levels of tanker traffic, were then integrated with information on accident probabilities, groundwater vulnerability and the distribution of population to evaluate the risks the waste movements posed to different localities. Comparisons between specific disposal sites were undertaken and these assessments were also expanded to encompass the wider region.
