I am making an application in java using GMaps4JSF where the person will enter the address on the map I'll take this coordinate and consult on my postgis base regions in which region this point is inserted and return this information on the screen. It's very simple. Google Maps Api uses the Mercator projection (EPSG: 3857), the coordinate of the queried map will be returned in this projection? I must redesign my data to it does not need to do conversions.
