The advantage of the map-query interface is that a map, coupled with the ability to vary the zoom level at which it is viewed, provides inherent granularity to a search process that facilitates approximate search. This capability distinguishes it from prevalent keyword-based conventional search methods that provide a limited facility for approximate searches that are realized primarily by permitting a match through a subset of the keywords. Being able to use spatial synonyms is important, as it enables users to search for data when they are not exactly sure what they seek or what the answer to their query should be. NewsStand's goal is to offer an alternative to the news-reading process and, more important, experience. Users can also constrain the spatial region and news sources; they need not be the same. This is a useful feature, as it enables users to see how one part of the world views events in another part of the world.
