Document Density Mapping with MetaCarta

One of the new features MetaCarta is offering is a document density map. When MetaCarta's Geographic Text Search (GTS) has finished compiling the results of a location-based search, it will offer the user a map of where it found the highest number of documents for a given location which is slightly different than what it had offered previously. The map is a coarse rendering of shaded pixels depicting "hot spots" of ever-increasingly higher concentrations of "hits" from the search. It looks like a coarse surface map. The user can then zoom in on the area and click on the map to retrieve the list of documents found in the search. So, MetaCarta gave GTS a slight tweaking to make its visualization of its search results just a little bit better.
