Hello Artem,

OK thanks. 

What would be really good, incidentally, would be a resource on the web which 
explains all the subtleties with projections and ellipsoids (which I probably 
only half-understand TBH), with appropriate conversion equations, so that 
people who haven't done formal GIS training could read and understand the 
theory and then easily implement the code. Maybe such a resource exists 
though I haven't found it yet... Maybe it should go on the OSM wiki?
