This paper is an analysis of the Category Individual Residence urban spatial structure along the National Route 20 (Koushu-Kaido), one of the major roads in Japan, and the degree of differences between locations and its changes between the points of time. The analysis was based on the GIS technique. Whilst, previous studies were based on municipal boundaries or mesh units as sources of data, GIS allowed the use of variable geographical units, Roadside zone, Inner zone, North zone, South zone, Blocks. As an example to apply the technology of GIS, 1986's sand 1991's building polygon data of the Urban Planning Bureau of Tokyo Metropolitan Government are used. The layers referred to the analyses is the building polygons with the amount of stories, building area, floor area and the material of the building. Two statistical analysis are executed; one is the test of the regional equality about the number of story of building, building area, floor area and fireproof building ratio.

The role of a GIS as a tool for a national information infrastructure can best be fulfilled once GIS standards are implemented. In this paper, we have identified what the contents of GIS standards in other countries are, and what should be the future direction for implementing a nation's GIS standards. Based on a detailed review on GIS standards in the USA, Australia, Japan and the United Kingdom, we derived the following: (1) A nations's GIS standards should include both geographic information content standards and geographic information service standards: (2) A nation's GIS standards should be a profile of ISO GIS standards: (3) Each GIS standards should be developed on the bassis of the Entity-Relationship Model using Unified Modeling Language: and (4) Experts in GIS should pay much more attention on studies on GIS service standardization. As for building the national GIS Standards for Korea, we recommend both GIS Content Standards and GIS Service Standards be simultaneously developed. GIS Content Standards include geographic feature content standard, feature classification standard, portrayal standard, rules for application standards, spatial reference model and terminology. GIS Service Standards include standards for data sharing such as metadata standard and transfer standard, quality standard, quality principle and portrayal standards.

The flood damage due to heavy rainfall caused by not only geographical factor, but also social factors. In this paper we derived the flooding potential factors, and analyzed resident's understanding of flooding through the Tokai disaster of Japan, occurred in september 2000. Furthermore, the urban rate obtained by the data comparison between 1975 and 1985 using GIS is evaluated to estimate the effect of rainfall-runoff mechanism due to the urbanization. These efforts could be served as the information of flood damage for the communication with the residents and it would be helped the minimization of flood damage.

When and Where, What kind of agricultural products will be produced and provided for the market? It is a commercial requirement, and also an academic questions to remote sensing technology. Crop physiology analysis and growth monitoring are important elements for precision agriculture management. Remote sensing technology supplies us more selections and available spaces in this dynamic change study by producing images of different spatial, spectral and temporal resolutions. Especially, the hyperspectral remote sensing should do play a key role in crop growth investigation at national, regional and global scales. In the past five years, Chinese academy of sciences and Japan NTT-DATA have made great efforts to establish a prototype information service system to dynamically survey the vegetable planting situation in Nagano area of Japan mainly based on remote sensing data. For such concern, a flexible and light-duty flight system and some practical data processing system and some necessary background information should be rationally made together. In addition, some studies are also important, such as quick pre-processing for hyperspectral data, Multi-temporal vegetation index analysis, hyperspectral image classification in support of GIS data, etc. In this paper, several spectral data analysis models and a designed airborne platform are provided and discussed here.

Intense competition for resources has forced many countries pay attention to their eyes to the ocean. Therefore, the disputes and the conflict over the delimitation of the EEZ and continental shelf will be sharpened. Since 1982 Law of the Sea Convention, Korea has opened the talks with Japan and China to discuss the boundary issues as the adjacent water zone is less than 400 miles between Korea and Japan and Korea and China. This study is to review the important rules and techniques for the delimitation of the maritime boundary which have defined in the Law of the Sea Convention and IHO-51 technical guide and to figure out how to build the maritime delimitation GIS DB to negotiate effectively with the neighboring countries. Definition of the base point and baseline will be the utmost important concept to delimit the ocean boundary. The policy makers and the specialists who prepare for the international negotiation meeting between the countries have to be ready to draw the maritime boundary for our best interest under the Law of the Sea Convention. The negotiation strategies and the principles can be made with the concrete and reliable database relevant to maritime boundary issues. So effective and fast strategic decision for negotiation can only be made based on maritime boundary delimitation GIS DB.

This study investigates the spatial patterns of distributed population in terms of population density, age structure, sex structure and family structure in Chou (smallest political city boundaries) of seven cities of Kitakawachi region. This displays the population dynamics of those cities from 1955 to 1995. It demonstrates how the populations of the cities are distributed with topography and with respect to the train stations. The demographic characteristics of the cities are visualized utilizing Arc View GIS capabilities with new visualizing technique in 3D environment based on data from Pasco Digital Map 2000.

Japan is one of the countries where the number of the elderly people is most rapidly increasing. This study aims to locate the suitable areas for the lodgings of elderly people, using Geographical Information System (GIS). We focused on the areas where the residents can live a usual and customary life, which includes walking, shopping, hospitalizing etc. Combining the geographical and municipal data along with some other information obtained from social factors, we performed selection of the optimal locations for welfare institutions. Out of 413 areas within Nagasaki City three different areas were found suitable for such elderly people lodging.

In this study, the authors evaluate the suitability of the candidate routes selected by the route selection method, which is developed by the authors, by combination of Geographic Information Systems (GIS) and Analytic Hierarchy Process. To evaluate the suitability of the candidate routes, from the viewpoint of the residents, we have considered element factors such as, population, household, aging situation, elevation, gradient, housing density and the Control Point. The results of this study are expected to assess the suitability of the candidate routes of the hillside transportation for the residents and examine the application limit of the route selection method.

We live in an age of information. We also live in an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. During the past few decades, we have recorded a phenomenal rate of growth. and experienced an array of environmental problems such as pollution, destruction of natural environment, and ecological disturbances. In response to these problems we has embarked on a study of Environmental Information System(EIS). This study has four major components. First, it describes the current status of EIS in Korea. Second, it provides a survey of EIS in other countries, specifically USA and Japan. Third, the study also presents an application of GIS(Geographic Information System)in Korea, USA, and Japan. Finally, the study outlines strategies to develop EIS in Korea.

Downtown cities in Japan are facing sharp fall in customers and continued shut down of shops due to decrease of population, increase in family cars and flowing of customers into the suburban large-scale retail stores. Omura City in Nagasaki Prefecture, Japan is no exception to this. For the revitalization of the downtown, many actions have been taken to open the vacant shops. However, transportation problem is the most important one to be solved for the citizens including the elderly people having difficulty in movement. Accordingly, this study was aimed at the revitalization of the downtown by substantiality public transportation. We have attempted to develop routes from the view-point of convenience by using Analytic Hierarchy Process (AHP) and Geographic Information Systems (GIS). As a result of the study, we were able to select three bus transportation areas by incorporating qualitative factors into the analysis. Finally, the study concluded that, revitalization activities of the downtown city itself is required in addition to re-structuring of bus transportation system for the revitalization of the downtown city.
