This paper presents a perspective of market analysis using Geographical InformationSystems. There are three types of applications in this area. The first is MarketingInformation Systems. MIS provides retail managers two kinds of information for presenting market maps and defining retail trade areas. The second is geodemographics, which is used as a geodemographic discriminator for consumer behavior. The third is trade area analysis by spatial analysis and mathematical models. Spatial Decision Support Systems are discussed for optimal location of public facilities and private firms.

This study attempts to clarify the actual road traffic circumstances and to investigate the change of accessibility of Nagano Prefecture from 1990 to1997 by using GIS. The main findings are summarized as follows. Firstly, there is a great difference between the speed of automobiles moving in the city and those moving outside the city. Secondly, as a result of extension of highway, time distance from Matsumoto to Hokushin area is reduced largely. Then, movement efficiency of automobile in Nagano Prefecture has improved, and the time required for the movement by 1km is improved from 1.3 minute to 1.0 minute.

Environmental issues involve a variety of underlying, interwoven factors.Geographical Information Systems (GIS) can be effectively utilized, both inanalyzing such factors and in organizing environmental preservation programs.This study aims to investigate, by utilizing GIS, the relationship between humanactivities and desertification in a semi-aridarea, based on which to proposefeasible measures toward sustainable aguriculture. An equation to compute theamount of soil loss was formulated from field data collected in Makutapora, andinput data to GIS are produced by digitizing existing materials available for thesurvey area, such as topographic maps and multispectral image data. The equationand data are then combined to GIS, in order to identify causal factors and assessthe areal distribution of soil losses

There is growing interest in developing Geographic Information Science (GlScience) curricula both in Japan and abroad. In this paper we examined GIScience education systems at 14 universities in North America for the 2005-2006 academic year. The GlScience education systems were more developed in North America than in Japan. Most of the 14 universities offer GlScience-related curricula, and several provide GlScience-related degrees or certificates. Seven universities offer GIS certificate programs, and five of those feature interdepartmental curricula, with classes from the geography and information science departments. The observations from this investigation are helpful in developing GIScience curricula in Japan.

In this paper we propose a method for measuring the area of attainable region from a given railroad station over the Tokyo metropolitan area in which railroad network is well developed. By calculating time distance between arbitral two stations using railroad network databases for 1960, 1980, and 2000, changes in the area of attainable region are used as a measure for advantage of the given place. We reveal that the growth of railroad network and the introduction of express train systems have affected not only on the reduction of travel time but also on the formation of multinucleated urban structure.

Understanding travel behavior is essential for urban transportation planning. This paper presents the development of a GIS-based system for understanding individual travel behavior under space-time constraints and its application to the graduate class of environmental information system in spatial planning and policy. Required input data consist of activity schedules, transportation networks and activity opportunities. Potential Path Area (PPA) and the feasibility of participating in activities in space-time prisms can be simulated and represented on GIS, before and after changing constraints. The system is very useful for students to understand activity-travel behavior in urban space.

This paper estimates the benefit of a plan for information providing system on road administration by WebGIS. The system will reduce travel costs of visitors from their business establishments to a road administration section of a city office. The authors had individual interviews with the visitors at the section of the Ichikawa City Office. Annual total sum of travel costs was estimated at 37 million yen at most. This paper also proposes formulas which expect the frequency of visits or the total sum of travel costs from the spatial distribution of the business establishments without questionnaires.

In this paper, walking distance and diverting ratio from Shibuya station, Tokyo, where redevelopment around the station is planned, to all surrounding facilities are calculated using pedestrian path network in the neighbor of the station. We observe that walking distance is shorter in northern and western parts, whereas it is longer in southern and eastern parts, and that diverting ratio is high in circumference and southern part of the station where the influence of a pedestrian overpass to stride over Route 246. We also estimate that average walking distance decreases by 139 meters by the installation of the high-level pedestrian decks around the station, which is planned in a redevelopment plan in the neighbor of Shibuya station.

This study aims to evaluate the accessibility to the natural environments of residential environment evaluation in Utsunomiya City. For the purpose, the evaluation functions which use multiple regression analy-sis with residents'evacuation of accessibility as the criterion variable and the traveling time to the destinations as explanatory variables were developed using GIS.As the result, compared with the case which the air distance was used as explanatory variables, the coefficient of determination becomes more than two times. And this result shows that traveling time is an effective factor and GIS is useful tool for this kinds of study.

In this study, the analysis system of evacuation action at the time of flood was developed using GIS. The system applied the network analysis which considers multiple refugees and shelters simultaneously and searches the shortest paths through the network links from halfway of the links. Moreover, the evacuation action was simulated in detail by linking network analysis and flood analysis. As a result, it was shown that the analysis system is applicable to plan suitable evacuation routes and shelters, and enlighten the residents on the importance of early evacuation.

Natural disaster might cause traffic congestion, changing traffic network. In this paper, we propose the way of developing the road condition analysis, animated traffic simulations of GIS and apply to the traffic situation under the Tokai downpour by using travel survey and tachometer of the drivers who had been driving under the disaster, from 9.11 to 9.12, 2000. As a result, it was revealed that many drivers who had driven at that time had involved chronic traffic jam and it took many hours to reach to destination.

Two methods and a system for the measure against slope failure disaster using GIS are proposed in this paper. 1) Method of extracting cliff and potential area, suffered from slope failure, by DEM and Landuse data. 2) Method of extracting potential slope failure area by rainfall data, and a system of conveying this information to local residents. These methods can be applied to many places where these data are available. Moreover, dangerous cliffs and the areas are extracted at the same time even in wide city area. These methods will allow us to extract dangerous cliff and area without fieldwork, and this information will help local residents with proper actions. Minami ward, Yokohama city, was selected as a study area.

It is a fundamental process of urban planning to determine the planning area or to divide the area into the zones in which the tendency on urban activities at each place is similar to others. The area dividing process can be formulated as a minimization problem of the sum of the generalized distance. This problem can be numerically solved by using Hopfiled Network which is a basic model of neural network theory.Applying the proposed method to the actual urban lattice data, we can obtain divided zones.

Recent years, for development of computer hardware and software, information processing is about to accoplish remarkable progress. While, today, space use on each floor of buildings is more various, and has become difficult to be grasped by methods of numerical or two-dimensional.As a method of research, analysis and valuation on various space use on esch floor of buildings, we propose "three-dimensional mesh map" which is made of a cubic lattice with one unit-3.5m×3.5m ×3.5m, which is made out by three-dimensional computer graphics.

This paper aims to measure the positional accuracy of digitized point data by mouse operation. Fifteen operators digitized 225 representative points of buildings in the experiment designed with Latin square. The frequency distributions of X and Y deviations between digitized point locations and the centers of gravity of buildings on the original drawing are more peaked relative to the normal distribution. An analysis of variance and multiple comparison show that the differences among building coverage and among operators are significant. Substituting estimated deviations into a formula made by Teraki(1999), this paper estimates the probability of identifying buildings by the point-in-polygon interpolation.

The purpose of this study is to improve methods estimating for the distribution of population along urban roadways with heavy traffic in order to account the population exposed to serious noise or air pollutant. Recently, a census covering the whole country provides the population data with the Basic Unit Blocks and the locations data of its center point. Population density in the range of every 10 meters from the roadway is estimated by allocating the population data into the polygon data of blocks on the market. For more detail, the number of population could be allocated into polygon of buildings according to floor space and floor uses. The linear approximation of census population data could be applied for estimating the spatial distribution of people, if the polygon data are not available for the targeting area.

There are two important problems in clustering of small area statistics: handling of outliers in small area statistics and complexity of spatial distribution of typologies created by classifying small areas. The purpose of this paper is to show a procedure of geographical clustering using small area statistics in order to solve these problems. According to the results of two examinations, Self-Organizing Maps (SOM) constraining the range of updating weights is better classifier than K-means. As to the issue of simplifying spatial distribution of typologies, we showed that there are relations between the level of the spatial smoothing and the spatial extent of the study area.

This paper presents an expanded definition for measuring geometric attributes such as size, shape and location in irregular zones. The expanded definition involves identifying size with area, shape with edge roughness or smoothness and compactness, location with number of adjacent zones and distance to the central zone. A zone which has special geometric attributes and keeps significant spatial correlation and spatial interaction closely to adjacent zones is called prominent zone in regional science. The prominence of zone can be measured by prominence index which is a stationary distribution of Markov chains transition matrix identical to a spatial weight matrix. In this study, spatial clusters composed of prominent zones are extracted using by K-means cluster analysis, and relations between prominence and geometric attributes of irregular zones are showed by correlation analysis. This study reveals that prominence index and geometric attributes provide effective measurements to evaluate prominence of irregular zones.

A probability density function of demand for automated external defibrillators (AED's), which is based on the distribution of demand points by kernel density estimation method, is estimated from the data on occurrences of cardiopulmonary arrests. The probability that someone can be saved by AED's is formulated using probability of survival to hospital discharge. "Supply effect" is expressed as demand density multiplied by this probability of saving, and the locations of AED's are optimized by maximizing supply effect in the entire region. The results show that optimal locations tend to cover the center of the city and that the supply effect is approximately proportional to the number of AED's.
