Abstract:
The combination of Geographic Data Warehouses (GDW) and Spatial OLAP (SOLAP) provide efficient browsing and storing of very large spatio-temporal databases. However, some advanced techniques of geovisualization are not well supported in many of these tools. Three-dimensional Thematic Mapping through Virtual Globes is one of them, and it can provide a friendly but powerful mechanism for summarize visually huge amounts of geospatial-analytical data and their changes over time. This paper shows the GlobeOLAP, a prototype of a Web-based SOLAP tool that allows the customized generation of many types of Thematic Maps to be visualized three-dimensionally in a Virtual Globe (Google Earth), together with the traditional tabular view. This tool can improve management decisions by allowing managers to identify patterns and build knowledge in a spatial realistic environment.
