1973?
are you not doing a geography degree?
WTF is a UTM zone anyway?
LOL I had to google it. I've heard of it but even after googling it i'm non the wiser.
WTF is a UTM zone anyway?
universal transverse mercator projection. commonly used by the military as a georeferencing system.
how about 30 and three quaters ? does it realy matter ? 
No idea on the zone. UTM is a mathematical method of projecting an [u]almost [/u] round surface (the earth) on a flat map. I think it matters a lot because the zone defines the almost bit - get the wrong zone and you can be hundreds of meters out. Which makes anybody who positions things (military, industry etc) upset.
Makes a spherical world flat! Basically split the globe up into segments (like an orange) and then fit the outside face of that segment to a rectangle. All done by horrible maths.
Much easier to work out distances between points (as it's metric) than Geographical coordinates (in which a distance would be in arc seconds).
Not used too much in the UK since we have the British National Grid, this is a transverse mercator projection so not too different but means we don't have to cross utm zone boundaries as we move across the country.
EDIT the zone number essentially refers to the segment of the globe that you are in (each segment is 6 degrees wide). it does indeed make as massive difference to your coordinates since each zone has it's own origin (0,0 in eastings and Northings) so coordinate positions are only relevant to the zone you are in.
Elaine anne- it does matter because I've just plotted the results for yesterday's geological survey as being in the North Sea following a google when it was actually in West Yorkshire 😳
Jambo- I do rocks.

do you not need to know where they are?
Ive got it wrong at work before when plotting location of offshore developments. Simple mistake that makes you look a compltete tit.

......which according to the film 2012 could quite possible be feasible!
Know the feeling though - have spent the morning converting data from one projection to another - one typo could put it in a completely different part of the world.
Radical cartography and psychogeography are far more interesting.
