This is really a simple/naive question, but I’m fairly new and please be kind with your responses. More specifically,
the above image explains the screen (x,y) coordinates.
the second image above explains the map location (latitude, longitude) pairs in the map.
I’d like to know how to transfer between the two. For example, given the (x,y) coordinates, how to get the corresponding (latitude, longitude) pair in the map? On the other hand, given the (latitude, longitude) pair, how to get its corresponding (x,y) coordinate in the screen?
I think this might have something to do with the zoom level of the map? Any comments are greatly appreciated. Many thanks !
