A thresholded heatmap, maybe. But really the area thingy seen on zooms lower than buildings is a concave hull on slightly expanded outlines of "interesting" buildings (as I said the ones which contain most of given POIs). The area only includes most concentrated areas, so lone interesting buildings don't count toward it. Therefore, it's a hybrid of a point-in-polygon, spatial buffer, concave hull and a heatmap. >I still don't see the innovation. The notion that something is not innovative just because it uses familiar methods is fundamentally wrong. A solution consists of a method (like an algorithm) and its application, that is a problem it solves. If you apply an existing algorithm in a new and meaningful way, that also is innovative. In fact, if the former were true, we would have to dismiss half of science papers, if not more. The classical heatmap on some random OSM hacker's website serves a different purpose - analysis. It hasn't been used on general purpose maps in a context of presenting "interesting" places automatically. Still, if anybody can give an example of anybody doing similar thing as Google did, I stand to be corrected. The bottom line is that we don't live in a vacuum and it's beneficial to look for fresh or unusual ideas wherever they come from. No need to perpetuate an echo chamber.
