Farthest N E S W

Sarah tried to start a meme using the mapping sites to track "Farthest North, East, South and West" you've travelled from your current location. My map is below.

North: Edmonton, Alberta, Canada
East: Nice, France
South & West: Queenstown, New Zealand

Note that the resulting shape isn't a convex hull of my travels. To do that it would have to include London, England and Hawai'i, USA.

And yes, I could have done the map with New Zealand on the right, so I'd have a bigger area, but that would be cheating.
