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.

We considered the specification of temporal geospatial information, and produced a temporal geospatial dataset of the area close to Kenkyu-Gakuen Station of the Tsukuba Express in Tsukuba City. Using geospatial data of each year generated from the temporal geospatial dataset, we conducted a temporal spatial analysis of human impacts such as the development of a new traffic network and land surface change such as land use. Effective temporal spatial analysis is possible using a temporal geospatial dataset if the dataset is revised with high temporal resolution.

The aim of this paper is to examine regional differences in the prevalence of pollinosis by social area type in a geodemographics dataset by carrying out binomial logistic regression analysis on the 2002-2006 Japanese General Social Surveys (JGSS) data. The results indicate that people living in rural areas and working in the agriculture and forestry industries are less prone to contracting pollinosis, and people with a higher household income have a higher risk of contracting the disease compared to those with a lower household income. These findings are consistent with the hygiene hypothesis that sanitary environments impair normal development of immunity and increase the risk of contracting allergic diseases. This study also exemplifies the usefulness of geodemographics as a concise indicator of the local environment for explanatory analysis of environmental health risks of pollinosis.

<p>Sun glare may be a major hazard for car drivers in the winter. This is because the sun is low in the sky during the morning and evening where the roads are at their busiest with people driving to work and to home. The purpose of this article is to analyze what to extend the sun glare disability arises in rectangular area. We derive the probability of sun glare by use of computing the number of trips driving toward the sun. In addition, we examine how the shape, the direction, the latitude of the rectangular study area affect such probability.</p>

How influential and effective GIS could be in the society was actively discussed in English-speaking countries through the 1990s. Noticing potentials in “Public Participation GIS (PPGIS),” many conducted research. This study reviews research trends and practices related to “GIS and the Society,” promoted in English-speaking countries, and discusses its possible directions in the future. One noticeable trend is that, due to rapidly advancing information-communication technology and its global-scale availability, now citizens can participate in more diverse ways, using the web technology. Taking this trend into discussion shall lead to further development of PPGIS research, from which the sites of citizen’s participation will hopefully benefit.

The image of region often is not identical with the actual boundary of the region, sometimes the image crosses over the boundary. In this study, we focus on the building name, which includes place name, and analyze about the determinants of place name exuding (exuding phenomenon). We use GIS data of 23 wards of Tokyo in Japan, and focus on the 934 place names to analyze the spatial distributions. Our findings show that railway-station, high-rise buildings, and large infrastructure (river) in the region influence the place names to cross over the region because they play as a symbol in the region. Moreover, we can see low-exuding-places are located around high-exuding-places, because high-exuding-places are distributed overall in Tokyo. The average distance of exuding is nearly the same as the distance of walk, and the distance of exuding is high near the boundary of Tokyo, because of the frequent use of car in the area. It is found that the image of region is relevant to the range of life and activity.

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.

The purpose of this study is to develop a quantitative site grouping method as a supportive measure for prehistoric settlement researches. One of the basic procedures in settlement archaeological studies is to group individual sites. Grouping scale must be determined in relation to hierarchical level of the social units (e.g. micro level, semi-micro level, macro level). Conventional methods (i.e. Voronoi, Buffer) for site grouping had a difficulty in taking hierarchical structure into account. In this study, hierarchical grouping is attempted by utilizing the scale flexibility of cluster analysis. Spatial extents of the units were also measured through 'time-distance', which simulates the Jomon people's sense of distance. Sites were clustered into groups by suitable threshold values, which were estimated by spatial statistical scores calculated by K-function. Effectiveness of the method was verified by observing its correspondence to the site distribution with specific hierarchical structures. The verification confirmed the developed method to be relevant for quantitative and hierarchical grouping of Jomon-sites.

This paper focuses on two types of sports clubs located in Fukuoka City and analyzed their service areas using GIS. The service area of each type of club was compared with that of three sports clubs located in Kagoshima City. The results of the analyses in this study are summarized as follows:1) About 90% of the members are included within circles of 4km and 6km defined around "Next to Residential area" and "Terminal" types of sports clubs respectively. 2) For the type of "Terminal" sports club, intermediate level of service area was expanded to the districts along subway and rail-way. 3) Market penetration ratio for "Next to Residential area" type had fallen more sharply than for "Terminal" type with the increase of distance from the club. 4) As the result of comparing with the clubs in Kagoshima city, these two sports clubs in Fukuoka city were classified as the concentrated type in terms of the inner structure of service areas.

In this paper we propose a new interpolation method using monotone functions to generate a digital elevation model (DEM) from contour lines of a topographic map. The proposed method has the following features. (1) It does not yield unnecessary vibrations that the other methods like the spline interpolation may often do. (2) It can generate more suitable surfaces of DEM. (3) It may choose and utilize the simple-averaging method or the Grimson's regularization method as a post-processing to make the surfaces more smooth. We carried out the experiments to verify the effectiveness of our method. From the results, we conclude that our method is more effective than the traditional methods like the spline interpolation, Akima's interpolation, etc..

This paper reports the development of a time-series topographic map viewer "Konjyaku Map 2": Capital, Chukyo and Keihanshin Area Edition, working on Windows 2000/XP/VISTA . Although there are considerable needs for acquiring knowledge of the past status of local areas, it takes a lot of time and effort to satisfy such needs. The software shows old topographic maps on a scale of 1 to 25,000 since the early 1900s and is downloadable from the internet. The software was developed for viewing maps with these fairly simple functions and can thus be easily operated.

Due to the increase in a necessity, operability, and data availability, spatio-temporal analysis has been gathering popularity. However, there are few studies focusing on systematic reviews of it. This paper first shows basic concepts for spatio-temporal analysis such as geometrical representation of entities and changeability of attribute values over time. Then the paper constructs a matrix showing the characteristics of earlier studies. The matrix consists of two stages, where the first stage concerns the temporal representation and types of the entities, and the second stage concerns spatial representation, changeability of location, shapes and attribute values. The matrix helps us to understand the characteristics of the studies and uniqueness or similarity when compared to others.

Demographic composition, e.g., population composition by age-groups, is one of the most basic information for discussing regional issue or planning. The present study compares the future Japan through 2010-2060, estimated by National Institute of Population and Social Security Research, with all municipalities in 2010 from the perspective of demographic compositions classified by fiveyear age groups (0-4, 5-9, ..., 90+). The (dis-)similarity of compositional data can be measured with Aitchison distance, one of the core concepts of compositional data analysis. We create choropleth maps based on Aitchison distance. The maps, for example, indicate that the demographic composition of Sobetsu-cho of Hokkaido prefecture of 2010 is the most analogous of the future of Japan of 2060.

Many studies have investigated the relationships between gravity data and subsurface caldera structure beneath the area. Difficulties may arise, however, for these analyses because of different interpretations of the buried rims of the calderas. For buried calderas, ground deformations and erosional processes including landslides have significantly reduced the appearance of the original caldera rims. Generally, the interpretation of caldera rims is based on gravity data together with geological observations, because the preserved rim has a large negative gravity anomaly that reaches minima over the marginal low-density ridges. In this study, we propose an effective method to enhance the delineation of caldera rims from gravity data using watershed delineation in GIS. The proposed method incorporates a correlation analysis to appropriately assume a rock density to correct the gravity anomalies, and a band pass filter to eliminate noises in the data. Using gravity anomalies corrected with 2.60 g/cm3 of assumed rock density, and with bandpass filter that spanned the size-range of calderas, we have successfully extracted rims of the late Cenozoic calderas from NE Honshu, Japan.

This paper aims to improve the confidence limits of the results of overlay and to increase the efficiency of the line work. First, regression analysis shows that the area sensitivity measure has a quadratic relation with the fuzzy tolerance. Second, the frequency distributions of sliver polygons are compared with those of the other polygons on compactness, perimeter and area. Compactness characterizes sliver polygons more distinctly than perimeter or area. Third, discriminant analysis and logistic regression analysis correctly classifies 93 and 94 percent of polygons into sliver polygons and the others respectively.

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.

We developed a flooding-type algorithm for drainage network extraction and show a full program source in the language C. The program generates automatically Drainage Direction Matrices (DDMs) from Digital Elevation Models (DEMs) with sink holes. By using a random technique of random walk type, the drainage networks are processed adequately in flat plains or alluvial fans.
