项目摘要

Studies with digital geographical data including maps, census data and remotely sensed data are found in human geography, natural geography, economic geography and so forth. In carrying out these studies, however, it is difficult to find where necessary data are available ; there is no systematic way of sharing expensive geographical data among universities ; and there is no system of sharing research information about software. The objective of this project was to resolve these difficulties, and we have almost achieved this objective. Our major outcome is as follows.1.Catalog server system. In the past, clearinghouse was used for searching map data. However, this system could be run only a large organization with technicians, and it could not be managed by universities. Therefore, we have developed an easy system that university researchers can easily manage. At present, the Center for Spatial Information Science at the University of Tokyo(CSIS) runs this system, which can be used by any researchers for academic use. In the near future, branch universities will run this system.2.System for making catalog contents. We have developed software with which researchers can easily make catalog contents.3.Construction of catalog contents. Using the above system, we have constructed catalog contents of digital maps, census data and Zmaps which are frequently used by researchers. We have also constructed catalog contents of various maps toward the National Virtual Museum of Maps.4.Data sharing system. We have developed a system with which researchers can down load the data that are searched by the above catalog server system.5.Software search system. We have developed a web system for finding software packages, and a system of down loading free software packages.

人文地理学、自然地理学、经济地理学等领域都存在着对地图、人口普查数据、遥感数据等数字地理数据的研究。然而，在进行这些研究时，很难找到必要的数据。没有系统的方法在大学之间共享昂贵的地理数据；并且没有共享软件研究信息的系统。这个项目的目的就是为了解决这些困难，而我们几乎已经实现了这个目标。我们的主要成果如下： 1.目录服务器系统。过去，交换所用于搜索地图数据。然而，这个系统只能由拥有技术人员的大型组织来运行，并且不能由大学来管理。因此，我们开发了一个简单的系统，大学研究人员可以轻松管理。目前，该系统由东京大学空间信息科学研究中心（CSIS）运行，可供任何研究人员用于学术用途。近期，各分校将运行该系统。2、目录内容制作系统。我们开发了软件，研究人员可以使用该软件轻松制作目录内容。3.目录内容的构建。利用上述系统，我们构建了研究人员经常使用的数字地图、人口普查数据和Zmaps的目录内容。还构建了国家虚拟地图博物馆各类地图的目录内容。4、数据共享系统。我们开发了一个系统，研究人员可以通过该系统下载上述目录服务器系统搜索到的数据。5.软件搜索系统。我们开发了一个用于查找软件包的网络系统，以及一个免费软件包下载系统。
