1: What are the three main types of data warehouse usage?

2: A spatial DW is one that contains spatial data (among whatever else is appropriate). And when you consider a DW has a fairly wide scope, it is difficult to consider it exclusively 'spatial'. 'spatial DW' is more a marketing term from vendors who support spatial data. Spatial data are simply additional attributes that provide spatial context to measures.
