dschmidt Posted June 1, 2007 Share Posted June 1, 2007 Check out the new free online tool available at: http://www.geomidpoint.com that could come in handy for the sport of geocaching. You can quickly find the true midpoint coordinates (based on a spherical earth) for two or more cities, such as Chicago, Los Angeles and London, or you can enter your own latitude/longitude points and get the exact midpoint coordinates. You can see your points and the midpoint on a map (Google maps). Quote Link to comment
Team MAG Posted June 2, 2007 Share Posted June 2, 2007 THANK YOU THANK YOU You have just helped me with a puzzle cache I've been working on for over a month - tracking down high school geometry kids with a TI82 hasn't worked so far.... Quote Link to comment
dschmidt Posted June 2, 2007 Author Share Posted June 2, 2007 No problem. I've just been having some fun playing around with this thing. Quote Link to comment
+Knight2000 Posted June 2, 2007 Share Posted June 2, 2007 tracking down high school geometry kids with a TI82 hasn't worked so far.... I had a TI-81 in high school. It was great for writing messages back and for with my girlfriend (now my wife.) Other than that, what was it for? Quote Link to comment
+All Jacks Posted September 23, 2015 Share Posted September 23, 2015 I still have my TI82 but it's not doing me much good with a puzzle on my desk. I have six cities each with a distance to the cache. I need a Survey convergence calculator or a Masters in Maths Quote Link to comment
+J Grouchy Posted September 23, 2015 Share Posted September 23, 2015 Another useful site: http://www.geocachingtoolbox.com/ Is there a limit on the number of points you can input? I used over 1000 for my most recent cache. Ended up just using Excel to average the coordinates. Quote Link to comment

I used over 1000 for my most recent cache. Ended up just using Excel to average the coordinates. I was looking at that site and it says you have to "authorize geocaching toolbox". What does that mean? I'm too chicken to take a chance of downloading something potentially "bad". But it looks like a really cool website! The only maps I saw were in Europe, though; does it include the US? Quote Link to comment
