Has anyone written any code to convert lat/lon to Mercator projection in metre
units (metres east and north of the intersection of the Greenwich meridian
and equator)? There's plenty of lat/lon to Mercator converters around (e.g.
that in JOSM) but they give the answer in obscure units, e.g:
I need this to generate Freemap tiles using Mapnik in mercator projection, but
I want to be able to specify the scale in something like pixels/km.
