[Termes IGN] utilisation du solRésumé : (Auteur) Over the last fifty years, worldwide city shrinkage has become an increasingly common phenomenon. How to deal with the shrinking issue, and any problems caused by its chain effects, still remains a challenge for researchers from various disciplines. In this paper, Japan’s shrinking phenomena is analyzed based on a case study of Katsuura City. Changes in land use, population, industry, and residential preferences are detected through an analysis of census data, land-use maps and questionnaire surveys. On the basis of this analysis, a simulation model consisting of a land-use change model generated by rent-gap theory-based cellular automata combined with a residential migration decision model based on a multinomial logit model is built to project the current pattern of shrinkage in the case study area, and in order to compare various policy scenarios.

[Termes IGN] pollution atmosphériqueRésumé : (Auteur) This study demonstrates the potential value, and difficulties, in utilizing large-scale, location aware, administrative data together with urban modeling to address current policy issues in a timely fashion. We take advantage of a unique dataset of millions of odometer readings from annual safety inspections of all private passenger vehicles in Metropolitan Boston to estimate the vehicle-miles-traveled (VMT) implication of alternative metropolitan growth scenarios: a sprawl-type “let-it-be” scenario and a smart-growth-type “winds-of-change” scenario. The data are georeferenced to 250 x 250 m grid cells developed by MassGIS. We apply a greedy algorithm to assign Traffic Analysis Zone (TAZ) level household growth projections to grid cells and then use spatial interpolation tools to estimate VMT-per-vehicle surfaces for the region. If new growth households have similar VMT behavior as their neighbors, then the let-it-be scenario will generate 12–15% more VMT per household compared to the winds-of-change scenario. However, even the “wind-of-change” scenario, will result in new households averaging higher VMT per household than the Metro Boston average observed in 2005. The implication is that urban growth management can significantly reduce GHG but, by itself, will not be sufficient to achieve the GHG emission reduction targets set by the State for the transportation sector.

[Termes IGN] risque naturelRésumé : (Auteur) Natural hazard analysis often makes use of alphanumeric data sets whose content is mainly expressed using natural language expressions that describe where and when events such as eruptions, avalanches, floods, etc. took place. However, a lot of expressions used in natural language are vague and imprecise and especially those which are used to locate places (around, near to, north of, etc.) and dates (between 1710 and 1711, at the beginning of the century, etc.). Some works propose approaches to define a spatial expansion representing the localization of any vague spatial information. Yet, these approaches do not allow to define any spatial or temporal localization that takes into account their physical environment: topographical or meteorological elements of the studied ground, nature and the characteristics of the observed phenomenon, etc. We propose a methodology that allows to improve the localization and the cartographic representation of imperfect spatial and temporal information. This methodology relies on a specific extension of Spatial ML and TimeML markup languages and an ontology for the integration, quantification and representation of imperfect spatio-temporal information expressed in natural language in order to locate natural hazard phenomena. In this paper, we present the elements of the STELLA (Spatial - TEmporal LocaLizAtion) methodology and framework .

[Termes IGN] venteRésumé : (Auteur) Simulating the dynamics and processes within a spatially influenced retail market, such as the retail gasoline market, is a highly challenging research area. Current approaches are limited through their inability to model the impact of supplier or consumer behavior over both time and space. Agent-based models (ABMs) provide an alternative approach that overcomes these problems. We demonstrate how knowledge of retail pricing is extended by using a ‘hybrid’ model approach: an agent model for retailers and a spatial interaction model for consumers. This allows the issue of spatial competition between individual retailers to be examined in a way only accessible to agent-based models, allowing each model retailer autonomous control over optimizing their price. The hybrid model is shown to be successful at recreating spatial pricing dynamics at a national scale, simulating the effects of a rise in crude oil prices as well as accurately predicting which retailers were most susceptible to closure over a 10-year period.

[Termes IGN] rivièreRésumé : (Auteur) Rapid population growth and human activities (such as agriculture, industry, transports...) development have increased vulnerability risk for water resources. Due to the nature of river networking distribution, the interactions between hydrosystems and human pressures are difficult understand. In addition, many hypotheses about river water pollution can be formulated. In this context, knowledge discovery is a promising process to better understand and manage such phenomenon. We have combined the results of several data mining methods to extract actionable knowledge from data collected by stations located along several rivers. First, data are pre processed (aggregated) according to different spatial relationships, which leads to the extraction of semantically different patterns in the second phase of the process. Then, the resulting datasets are mined to extract sequential and spatio-sequential patterns. Finally, patterns are filtered using a new quality measure based on the notion of contradiction. Such elements can be used to assess specialized indicators to assist the experts in river water quality restoration.
