Hi Christopher,
Hi list,
I have tested the reprojection according to your doc but it does not
work.
See the very simple attached example. They are two points that should be
in the south of France but they appear in the south atlantic ...The two
points are latlon coordinates (EPSG:4326) and the map is set to a
sphericalMercator projection.
Example :
