Abstract
 The Spatial Data Warehouse of Seoul Track: GIS Organization, Management and Implementation Author(s): Impyeong Lee, Jae-Ho Han, Yunsoo Choi The Seoul metropolitan government has constructed a Spatial Data Warehouse (SDW) by integrating various kinds of geospatial data since 1995. The objective of its construction is to prevent duplicated creation of spatial information, make data access and acquirement more convenient, establish data registration and standardization, and increase data sharing and joint utilization. The SDW integrates all the spatial and administrative data generated by 13 individual GIS systems separately performing its own specific task and thus enabling more synthetic spatial analysis by combining these numerous data. It also takes a role of a centralized data source to provide spatial data required for each local department and the individual GIS systems. All the department can access the GIS information of the entire area of Seoul through the Internet data sharing framework created in the SDW. This presentation will describe the integrated models and operational results of the SDW.
