Probably not easily and maybe not how you are thinking about it.  I know of no GPS that can accept input data like water temp and display it on a map.  But GPS can output location data to an application running on a computer.  That application could also be taking input from your sensors.  The application could then take your sensor and GPS data and use it to plot information on a map.  But you would need someone to write that application (which would need to include knowledge of the actual protocol the GPS uses when it outputs its location data).
