Re: relative positioning of the map

You can also find the coordinates of any point interactively without
using code.
1. Go to http://mapki.com/index.php?title=Get_Lon_Lat
2. Zoom in to the location whose geocodes you want.
3. Click it. The display will show you the geocodes.
4. Cut and paste these into your code.

Alternatively, if you know a street address and want the geocodes, go
to http://geocoder.us/ and type in the address.

Good luck!
