I'm using PHP to generate a GET request to the Static Map API. I can get around 300 markers to appear on a map but no more. If I use the default marker color (black) I can get more markers but I need to have different color markers. Since I'm not limited by a browser's URL limitation, what is the limitation for a programatic GET request?
I'm looking for a Static Image mapping API that allows for unlimited markers on a high resolution map. Does such a thing even exist? I could use POST to get around any GET limit, but apparently the MapQuest API does not support POST.
