I have between 10,000 and 50,000 map points that need to be shown within a city space.
Each of those markers has a lat and lon, but when loading them into google maps with blocks I can only really load all of them, this takes a while.
How can I store them and only show them based on the coordinates?
Google Maps itself has a “Search This Area” button to only load results.
I can create a button (thought I would rather it be automatic), so how can I load them (very quickly) based on that area?
Can I find the grid that maps is showing and the run through a stored list of points to filter out the ones that fit within that?
