Sorry if this sounds naive but I have no background in GIS and have trouble finding relevant information.
I want to zoom/move a map to fit a set of POI. So: Given a set of coordinates (WGS 84 reference frame) I want to find the bounding box (without any libraries).
There is also GMSCoordinateBounds (which I'm not allowed to link to for some reason) in the Google Maps iOS SDK that does this. Do they also just do 2D math?
