Study on Topological Relationship and Spatial Reasoning in GIS;

A hybrid spatial reasoning approach based on fuzzy sets;

Making use of the concept of symmetry group,spatial reasoning is implemented and the construction in group theory for sets of possible relative locations among bodies can be developed.

Comparison of realistic geo-space and virtual cyberspace in China;

The paper discusses with reference systems of geo-space, how to use these reference systems and their limitations, and also gives the conditions required by reference systems used for digital geo - space.

Development of a regional geospatial framework based on multilayer model is an application system with spatial unified benchmark on the basis of regional geo-information,and by integrating specialized data and knowledge rules.

Based on various investigation and wide research on the current status of city geospatial fundamental data (CGFD),this paper gives the principle to set up the CGFD application mode,describes basic contents of CGFD and introduces the classification of users.

Geographical Space and Interest Groups:On the Practical Pattern of Community in China;

New Frontiers in MNCs Theory from a Perspective of Endogenous Interaction between Global Strategy and Geographical Space;

However,modeling geospatial relations should consider some special properties of geographical space and geographical phenomena.

This paper discussed the multi-scale and temporal issues in the application services for social public,database management and data updating of fundamental geographic spatial database combined with the construction of Ningbo geographic information system(NBGIS).
