I’ve been thinking about my GeoURL again (the link is on the SiteMap, too):

SiteMap

GeoURL

GeoURL

I added the stuff to my Wiki configuration:

$HtmlHeaders = '<meta name="ICBM" content="47.3787648948578, 8.52716503722805">'
  . '<meta name="DC.title" content="Home of Alex">';

Where did I get the numbers from? I visited http://www.travelgis.com/geocode/ and entered my address.

http://www.travelgis.com/geocode/

The seems to be absurd, however.

Let’s do some testing:

The next house number gets the following coordinates:

1. 3787648948578 latitude, 8.52716503722805 longitude. The same numbers!

Hm. The house 10 numbers higher:

1. 3791029892217 latitude, 8.52731103252156 longitude.

The distance: (sqrt (+ (sqr (- 47.3787648948578 47.3791029892217)) (sqr (- 8.52716503722805 8.52731103252156)))) ⇒ 0.00036826949999436975

Then consider that there are 10’000km per 90°:

          (/ (* 0.00036826949999436975 10 1000 1000) 90)
       => 40.91883333270775

Well, 41m for 10 numbers (ie. five buildings) makes sense after all. Amazing.
