Bookmarklet JumpToOsm

This bookmarklet retrieves zoom and coordinates in current url and opens a page on openstreetmap.org at the same place.

Recognized formats

Current url has to contain the following informations :

• either 0/0.000/0.000
• or zoom=0&lat=0.000&lon=0.000 (order not important and possible other parameters in between)

If none of these informations are found, no tab is created (an error message is displayed).
