| Abstract: | Information Society brings new requirements for on-line spatial data services. One of them is the entity-based spatial data framework that can integrate and support various social and economic information. Based on the analysis of state of arts of the field, the paper proposes a data model that can meet the requirement and can tie used for on-line information services via National Geo-spatial Information Service Platform. |
