I wanted to update my Apache FOAF-file. Especially I wanted to add geo data <foaf:based_near><geo:Point>. But where to get that information? From Google Maps? I havent found any “Get GPS” button so I had to search … and found a short article. Basically it is easy: the location is stored in the ll-Parameter of the URL
So open Google Maps, enter the adress and have a look at the “Link” on the right of the map. The ll-Parameter of that URL contains the GPS data in “latitude,longitude” format. So the first part would be inside <geo:lat> and the second in <geo:long>.
