Hi all,I've been thinking about extra colours for super hires imagery and been doing a little research. See the following list of some notable places sorted by their highest Bing zoom levels.
Hamburg 20 Vienna 20 London 20 Rome 20 Paris 20 Tokyo 20 Singapore 20 Montreal 20 New York City 20 Denver 20 Los Angeles 20 Kansas City 20 Mexico City 20 Port-au-Prince 20 Munich 19 Helsinki 19 Madrid 19 Warsaw 19 Moscow 19 Istanbul 19 Delhi 19 Tunis 19 Perth 19 Sydney 19 Amsterdam 19 Netherlands rural areas 19 Stockholm 19 Bogota 19 Santiago de Chile 19 Beijing 18 Cape Town 18 Rio de Janeiro 18 Berlin 17 Dublin 17 Damascus 17 Cairo 17 Lagos 17 Germany rural areas 17 Kansas rural areas 17It seems that all places that have hires imagery of z14 also have it up to z17 (of which z14-z16 are scaled versions, of course). So no need to introduce extra colours for anything below z18. Then the question is: How many colours make sense between z18 and z20 (the absolute maximum)?
I think one colour for each zoom level doesn't make sense, because the overall differences in image quality are too stark (compare for example NYC and Santiago de Chile at z19, respectively).
So what about: 14-17 "high resolution" 18-19 "very high resolution" 20 "ultra high resolution" ?And... which colours? I would have liked a kind of red-yellow-green scale, but I'd rather keep the green now in order to avoid confusion (old green tiles vs. new green tiles and so on). So I propose a dark green for "very hires" and a blueish green for "ultra hires" -- see the screenshot.
In anticipation of your comments, ant
