the sending of free e-card with varios motives (e.g. various map projections) is now available.
thank you for using it
For creating a data model of map projections, first it needs a systematization of map projections.
Both, a systematization of map projections as well as data model of map projections is found in:

I’d like to make a conformal world map, of low scale-variation, ror use as a wall-mounted map.
By “scale-variaton”, I mean: Maximum scale divided by minimum scale.
I’d be willing to construct something that requires a function of a complex variable, as do August and Oblated Stereographic, but no elliiptic integrals.
For a conformal world map, not interrupted (except of course at its convex border), what projection, meeting the above requirement, has the least scale variation?
For an interrupted conformal world map, what projection, meeting the above requirement, has the least scale variation?
In particular, can the Oblated Stereographic be used as a world map. Would it be oval, with low scale-variation?
What other oval, non-interrupted conformal world map is there (not using elliptic integrals)?
