Hi Joe, There are tricks there, such as egg-balancing on watching the water go down the sink in different directions - supposedly induced by the coriolis effect. This tells you all you need to know; it's not science, it's just a tourist spectacle. I once kept a tally on my bathroom mirror t

So essentially even the so-called 'scientific museum' was a sham/lie and the experiments they showed-off were made up. The real equator is nearby, but not where they said it was. A positive implication: all the mapping that is done to higher accuracies (<10m) is meaningful. On 26 January 2011 1

My understanding (which may not be correct) is that civilian GPS units are supposedly now as accurate as the military units in terms of latitude and longitude, but are deliberately much less accurate at altitude readings. ---Original Email--- Subject :[OSM-talk] military vs consumer GPS

Not too long ago I was in Ecuador at the "Mitad del Mundo" and noticed a fairly significant discrepancy between my own GPS and an official marker. The Mitad del Mundo is a monument setup to mark the equator, after which Ecuador is named. Obviously the equator is a line, but this is a single monum

Great, I love this idea. I'm working on mapping the trails of my community, and have wanted to create panoramas as I go. I'm in the USA, so I can't use OTV as is, but maybe in the future as it matures it will expand to the globe or I could setup OTV just for my area. Keep up the good work! -Josh O
