Things are changing, Google and Bing are going down to level 21 these days in certain areas... you can almost count the leaves on the trees: http://maps.google.com/?ie=UTF8&ll=37.763078,-122.424999&spn=0.000652,0.001013&t=h&z=21&vpsrc=6 It would be wise to redefine the built-in grid sets to reach 20 or 21. Just my 2 cents on the topic Cheers Andrea -- ------------------------------------------------------- Ing. Andrea Aime GeoSolutions S.A.S.
