Find coordinates by moving around the map

1. Drag and drop the map to broad location.
2. Zoom in for greater accuracy.
3. Drag and drop the marker to pinpoint the place. The coordinates are refreshed at the end of each move.

Find coordinates using the name and/or address of the place

Submit the full location : number, street, city, country. For big cities and famous places, the country is optional. "Bastille Paris" or "Opera Sydney" will do.
