Google maps api v2 - tens of thousands of markers?

You cannot visualize 7K markers at once on a map imo. I don't know what the goal of your question is, but I would have only the data uploaded that is in focus, e.g. On display and visible.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
