Spatial Datawarehousing [chapter]

Alejandro A. Vaisman, Esteban Zimányi
2017 Encyclopedia of Database Systems  
Much of the interest and success in this area can be attributed to the need for software and tools to improve data management and analysis given the large amounts of information that are being accumulated  ...  Third, and closely related to the previous point, the data that needs to be stored in the warehouse is getting more and more complex in both structure and semantics while the analysis must keep up with  ...  Merging these two technologies allows us to exploit the capabilities of both systems for improving data analysis, visualization, and manipulation of huge amount of spatial data.  ...
