Semantic zooming: Different representations for different spatial scales. When zooming away, instead of seeing a scaled down version of an object, see a different representation. The representation shown depends on the meaning to be imparted.
Example: Information Maps: See a city – zoom into restaurant and see what is served there – maybe zoom based on price instead (see expensive restaurants first, keep zooming till you get to your price range).
Working on the intrinsic structure of data and incorporating knowledge about its meaning (Meta data), semantic zoom adjusts the contents and density of information that is shown instead of only changing visual detail and scale.
