Yes, this service is pretty fast. Much faster than Swissgeo in any case. And the link generation procedure is much easier (simply click on “send by email” and copy-paste the displayed link).

But I personnaly find the rendered street maps quite ugly. On Swissgeo, depending on the zoom level, you can render a very nice street map or the official maps (in the appropriate scale) of the Federal Office of Topography, which are by far the most beautiful maps I have ever seen.

Alas, Swissgeo’s service is slow and the rendered maps are too small. But then, Swissgeo’s main service rests in its many GPS applications.

Does anyone know of a site similar to this one that covers Germany?
