as the topic suggests , how do i take the co ordinates for google earth and use them in oziexplorer
for example - the co- ords for levis lane petrol station in google is
32°49'0.93"S
151°50'37.79"E
and in oziexplorer
32°49.002's
151°50.607' E
anybody able to help ?

Ozboc,
The coordinate format you have shown above is incorrect. I assume that the "1" after 32 is to signify a degree symbol.
The top format is DDMMSS.SS (degrees, minutes, decimal seconds) whereas the second format is DDMM.MMM (degrees, decimal minutes).
To change in Ozi goto file==>configuration==>maps, and change the Lat/Long Display to "deg, min, sec".
Hope this helps,
Andrew

Remember, the whole world does not have to be in Degrees,Minutes and whatever.
That might have been handy back in William
Dampier's day - but its not all that hard to put your Gps, Ozi, Google Earth, Natmap etc in metres. most maps have had metric grids and co-ords for the last 30 years.
I find it much easier to picture how far 823m is than trying to figure out how far 0.354" are. And at least 823m is always the same length, unlike 0.354" which varies as you travel from
Darwin to Tazzie
Good Luck

Certainly easier to visualise in metres, but 0.354" is the same distance regardless of where you are.

Matt,
0.354" lat at
Darwin is 11m .354"lat and at
Hobart its 8m
1'00" lat at
Darwin is 1.85 km and at
Hobart its 1.36 km
Longs doesn't vary at all. Only Lats.
This obviously gets much less in Antarctica.
Good Luck - it looks like you'll get more
miles to the gallon in the north.

Swampy,
I sit corrected, but I think you have it bass ackwards. The distance between lines of latitude varies very little and only due to the fact that the earth is not a perfect sphere (an oblique spheroid) meaning that lines of latutude subtend a smaller arc at the equator than they do at the poles. In any case it is small enough to be insignificant for most applications.
The distance between lines of longitude however does vary more significantly. Unlike lines of latitude, longitudinal lines are not parallel and converge at the poles meaning they subtend a greater arc at the equator and down to zero at the poles.
Cheers,
Matt.

Matt,
Your right
Longs are the ones that vary

Swampy,
you raise a good point but one difference between using geographic coords (lats & longs ) versus Grids coord ( metres) is that geographic coordintes are unique to one location on earth whereas if you quote
grid coordinates you need to also quote the correct Zone, because the same
grid coordinates do exist in any one of the 7 zones in Australia and so on.

I'm not at home right now, so I can't explain how to do it step by step, but Oziezplorer has IMPORT/OUTPUT options that allows one to excahnge files to and from Gooogle earth. Do a search through the Help screen in OziExplorer using Google earth in the search options and it will explain what to do.

I seem to recall in the ExplorOz blurb, a couple of years back, that Exp0loreOz uses as it's conventioin Latitude and longditude, rather than the map
grid. Thought it was a bit strange at the time so have never bothered with ExploreOz coordinates.
Have I got the bull by the tail?
Of course, if you're using a handheld GPS and a paper map, maybe with a rule and a pencil, you need metres.
Regards,
Laurie.

To just throw in another grenade!
Imagine being in an aircraft and take off on the equator flying due west then turn 90 degrees to the right and you get to the GNP then turn 90 degrees to the right again and you get to the equator where you turn 90 degrees to the right again and you end up where you started from.
That is three 90 degree turns in a triangle that is supposed to only have 180 degrees and not 270 degrees.
That's Euclid for you!

Yes but No but Yes..
I think that turn at the north pole of 90 degrees will not intercept the equator at 90 degrees. Great circle
routes, rhumb line track and distance.. It's all lurking back in the dark corners of my mind somewhere!
