Nail -> Head... Except that the front end processing you suggest - through automated generalization - doesn't quite work. See the discussion of "GIS Maps" on James Fee's blog: http://www.spatiallyadjusted.com/2008/06/09/that-looks-like-a-gis-map/ There is another process of semantic interpretation that occurs during generalization. Using automated generalization routines results in maps that lack semantic richness. So a semantic geoweb would be good for more natural-language querying of spatial information - but the display will be a simple graph without the application of similar semantic principles to the visualization design process. -Eric
