Magnetic Compass ^{correct link this time!!}

Note: its positioned to fit the navigation control of Google Earth 4.3, not the separate compass, which has only recently begun working for me… Updates a few seconds after stopping moving.

Now have a way to determine the magnetic variation at a location have some other ideas for using this in Google Earth, eg magnetic bearing along a line, but this is a starting point. For example in the uk the variation is often too small to be really seen on the tiny control.

Thanks to heywhatsthat.com for the pointer to a webservice that gives the variation.

Update: Rather embarrassingly just noticed the link above was wrong! It was to a static compass. The link above has been updated, and it should now rotate! Sorry for confusion… (always wondered why this didnt get much traffic!)

Google Earth GPS

Once you have chosen a destination point, a small arrow will be shown in the bottom right of your Google Earth window, which points towards your destination! Ideal for use in the flight simulator, where you can play follow the arrow.

Note it only updates every 5 seconds, and comes with all sorts of disclaimers such as don’t use in life or death situations.

Note: I do also have a network link that shows the more exact bearing as a placemark label.

Updated to add: This has inspired a similar compass that rotates, nice work Gerardo64!
