[Openstreetmap] Formula for EPSG:4362 and questions to mercatorprojection?

[Andy Robinson]

EPSG:4362 is the unprojected Lat and Lon WGS84 is it not??

Not sure if this document is of any use in answering your question but I
find it generally of interest whenever I need to get my head around
something relating to the shape of our good planet and the transformation of
that shape.
