Is this possible with our projection? The closer to the pole the more
infinite the values get.
You might reproject, calculate the intersection of the borders with lat
85 and create a new end point of the borders instead of Southpole.
That way they could be correctly displayed.
Maybe insert the mentioned points as nodes into OSM and have osm2pgsql
filter away all nodes with lat >85. So at least the display of the
remaining lines should work.
