As the application fields of spatial information system continue to expand, different sectors in different fields are in desperate need of spatial data sharing to reduce the expenses of spatial data acquisition and to enhance its utilized efficiency. And spatial data interoperability is an effective approach to solve this problem. The present paper proposes a grid collaborative model for spatial data...
Rough set theory is emerging as a powerful toll for reasoning about data. Attribute reduction is one of important topics in the research on the rough set theory. Heuristic, discernibility matrix and matrix method are three usually methods for designing attribute reduction algorithm in attribute reduction based on rough set. Some researchers use matrix method to design attribute reduction algorithm...
