I see a lot of geocoding at work and one of the real mysteries is that null island is a fair few miles around. 0,0 isn't good enough for some people; 0.00001,0.

I see a lot of geocoding at work and one of the real mysteries is that null island is a fair few miles around. 0,0 isn't good enough for some people; 0.00001,0.00002, etc always have to get involved. Reliably catching that variant of the "Actually, I think your address is wrong" error needs a null island at least 50 miles across.
If I had to guess, there's a UI somewhere that allows people to drag a pin to the exact right location when it isn't close enough, and feeds that back into a geocoding database. They can only drag for so long across the Atlantic before they give up.
- yaur 10y agoI believe that anything between (1,1) and (-1,-1) is safe to kill if you are are only dealing with land based coordinates.
- Johnny555 10y agoThe distance between 0.00002,0.00002 and -0.00002,-0.00002 is only 0.006290km (or around 20 feet).
