The Integrative Storage and Management of Land Resources Data Center Based on Oracle Spatial

For the development of land resources informationization, the demand of data communion and information service becomes more and higher. It is necessary to construct integrative land resources data center to manage and maintain diversified thematic data, integrate dispersive and independent land resources information, in order to serve land resources management decision-making better and afford network social work. This paper proposes object-relation database management mode, and actualize integrative storage management and make the best of data center by Oracle Spatial. The paper analyses storage mode of data center, data structure of map document, and the integrative storage management of thematic layer based on Oracle Spatial technology. Experiment shows that proposed method performs very well in land resources management.
