Abstract
Spatial information science is a broad discipline originating geography, driven by data on real world phenomena. To promote the science and technology, it is very necessary to provide data platform where researchers can easily find base maps, statistics and fragmentary data material describing the changes or dynamics of the real world. Center for Spatial Information Science （CSIS）, the University of Tokyo, provides such a data platform. To further promote or encourage the advances of the science, CSIS collect, organize and integrate research achievements and data/knowledge product based on “space” or location. This article introduces such activities of CSIS, UT.
