The Map Room: Google Maps API E-Book, GeoChalkboard Blog
Eric Pimpler of the GeoChalkboard blog (which I was not aware of prior to this) has posted the the fifth revision of Mashup Mania with Google Maps , a free 52-page e-book on the Google Maps API; direct link to the PDF . Via AnyGeo .

Like many developers, my maps often have a great number of markers in a small geographic area, but these areas may be few and far between in the larger area of the full map. Perhaps you are advertising Mercedes dealerships and there are 23 in greater New York, 19 in Chicago and 51 in Palo Alto. If you put all these markers on a US map, you would end up with 3 indecipherable blobs at these locations. One solution is called "clustering", and by using the Marker Manager , you can just put a single marker at each of the three cities. These "cluster markers" serve as proxies for the many underlying markers. Typically an application would allow clicking on one of these cluster markers to zoom you in to that particular location, exposing the underlying markers.
DragZoom + Marker Manager = Cluster Zoom!

In the scoreboard, you can see an "AREA" score and a "LENGTH" score. The area score is my attempt to measure your deviation from the Google route, and is calculated by forming a shaded pink GPolygon from your route + Google's route, calling getArea() on the poly, and comparing it to the total area of the map. This isn't perfect, as sometimes the routes will cross eachother and cancel eachother out in the area formula.
