    金沢大学理工研究域環境デザイン学系The decline of the downtown has been observed in many cities across the world. In response, many small cities in Japan, for example, have been making regeneration efforts including development controls on large-scale shopping centers. It is extremely useful to analyze the potential effects of relevant planning policies before implementation. We developed an urban planning support tool, a multiagent simulation (MAS) model called Shopsim-MAS, to investigate the impacts of some downtown revitalization policies through consequent spatial dynamics of shop market shares. We discuss methods to model household behavior and to understand the market area dynamics of shops. The Shopsim-MAS model developed in this project has proven to be a useful means to analyze the impact of downtown revitalization policies in Japan. It is also expected to be further expanded for impact analysis of similar or more sophisticated urban policies in other parts of the world. © 2011 Pion Ltd and its Licensors

    Location-based services and GIS in perspective

    No full text
    This paper examines location-based services (LBS) from a broad perspective involving deWnitions, characteristics, and application prospects. We present an overview of LBS modeling regarding users, locations, contexts and data. The LBS modeling endeavors are cross-examined with a research agenda of geographic information science. Some core research themes are brieXy speculated

    Spatial queries with qualitative locations in spatial information systems

    We discuss locations as defined by their qualitative spatial relations to other features, dubbed qualitative locations (QL). We further propose a mechanism to handle queries with qualitative locations in geospatial information systems. For the realization of the mechanism for QL-based queries, we propose a conceptual framework that takes advantage of models of qualitative spatial reasoning to bridge the gap between conventional metric spatial information systems and the general publicÕs common-sense query of spatial relations in natural language.
