>>Hi,
>>
>>can someone explain me the formula for the projection "EPSG:4362" used in
>>WGS84?
>>
>>It looks a bit like a mercator projection but with the pole not as much

>>
>>
>>
>>And when we are on it: The mercator projection can not project the north-

>>
>>How comes, that there are maps of the whole world in mercator projection?

>>Are there a standard at which latitude the projection stops? If I stop at
>>+-85
>>degree of latitude, I get a map with roughly equal dimension in width and
>>height. Is the "border latitude" for mercator somewhere there?
>>
>>Or is some kind of magic used to project the near-pole regions in mercator
>>projection and the formular at
>>http://en.wikipedia.org/wiki/Mercator_projection is simple wrong?
>>
>>
>>Ciao, Imi.
