Displaying a map on your website is very easy: Install the module, publish it, done.
Set start location
Go to the module settings and switch to
Map configuration and edit the fields
Start position. You need the latitude and longitude values of a coordinate.
The easiest way to get the values is to search place on OpenStreetMap. The URL will show you the values, for example:
http://www.openstreetmap.org/#map=19/50.55543/7.28314. The first value
19 is the zoom level, the second one is the latitude
50.55543 and the third one
7.28314 is the longitude .
If anything doesn't work as expected or you have no idea how to solve a problem, feel free to open an issue or mail me your questions.
