Spatial Data-Dominant Generalization
Collect all task-relevant data sets
Generalize the spatial data first by merging the spatial regions according to the description in the concept hierarchy. Do not generalize beyond spatial generalization threshold limit (indicates max. number of spatial regions to create).
Non-spatial data is analyzed for each spatial object using the attribute-oriented approach.
Asymptotic run time of this algorithm is O(N lg N) where N=# of spatial objects
