Potentially adding to your woes you should take into account that people
mix up axis order. It is a well established traditional fight between
developers, geodesists and the rest of the world. This page [1] sums up
the main issue. If you find a script that dares to deal with this, feel
free to add it as a link to that page.

Best regards,
Arnulf.
