Hello, we need more than external links because we can each template, see: http://de.wikipedia.org/wiki/Wikipedia:WikiProjekt_Vorlagenauswertung/en Grettings Kolossos
What about scanning the externallinks table [1] to find every link to http://tools.wikimedia.de/~magnus/geo/geohack.php?language=de&... ? If all the information you need is in the link, this could be an alternative method.
