I'm developing a web application that allows the user to insert the coordinates of a point which will appear on a map.The map shows the provinces of a region but, before the point is shown I need to do a zoom of the province which contains the point.
How can I define the zoom level I need to visualize the province which the poit belongs to and its bordering provinces?
