Abstract: Spatial data fusion is a difficult problem in the field of geoinformation. The structure of Oracle geological data warehouse (GDW) and its advantages in storage and analysis are introduced in this paper. The spatial data organization model of Geodatabase of ArcInfo is elaborated. The authors emphasize on the study of storage model, spatial data and spatial index form of oracle spatial. The procudures of spatial data fusion is illustrated. Through customized development with ArcGIS, the GDW could fuse the spatial data in a high efficiency.

Key words: geological data warehouse, spatial data fusion, Geodatabase, Oracle Spatial
