Better late than never - welcome to the game! :) - Mampfred 07:59, 11 October 2012 (EDT)

Thanks a lot! I'll have some catching up to do to get to the same league as you guys! - Tilley

Welcome to Finnish geohashing community! - Isopekka 12 October 2012

Thanks! I'll send you a hashcard some day! - Tilley 23 October 2012

There is globalhash in your neighborhood tomorrow, I hope you have noticed? :) - Suurnesu 29 November 2013

OMG! I hadn't noticed! I just came back from this graticule's normal hashpoint and opened the site to start to write the report. But now that can wait - I have to figure how to get to the globalhashpoint! Nobody is gonna believe that - but it's really only less than a kilometer away! The only problem is that it's 50 meters into a small lake, the ice of which probably isn't thick enough to support a person yet. I may need to build a raft of some kind or try to borrow a rowing boat, or something else.. Need to go now! Tilley (talk) 07:08, 30 November 2013 (EST)

And the rest is history.. Tilley (talk) 17:27, 30 November 2013 (EST)

Congratulations on reaching the globalhash. You live in a lucky location! If the regular hash is near your home, the global one will also be "close" as it is a function of the fractional part. Easy to remember. Palmpje (talk) 07:52, 2 December 2013 (EST)

Wow! That is interesting! Is there some simple function to calculate how close the globalhash is in related to the closeness of the regular hash? Tilley (talk) 11:52, 2 December 2013 (EST)

It's very simple. The globalhash is based on the W30 coordinates (lucky for us...). Take the fraction (after the comma or dot, whatever is common for you). For lattitude (N/S) multiply by 180 and subtract 90. For longitude multiply by 360 and subtract 180. For your recent global hash, the fraction for lattitude is 0.8491884 so you get 180*0.8491884 = N 62.853912. For lattitude the fraction is 0.5767650 so you get 360*0.5767650 = E

27.6354. So... you just need to calculate how far away 0.01 of the daily coordinate is in each direction. Then you can see how far out the global hash is. My "sweet spot" for 52, 4 is in the North Sea, hard to judge.... Leave a note on my talk page if you need more help. Palmpje (talk) 15:35, 2 December 2013 (EST)
