I'm also dealing with the amount of data to be displayed from a database. And my approach was to build a server side algorithm that would filter the information ( in my case pictures) to be overlaid in the map. The thing is.. as you mentioned before, I don't know if there's a way on knowing the area of the map the screen is covering.. it would be helpful for me to know this and like that I could filter the pictures to be overlaid by taking out the ones out of that screen area..
Any suggestions?
