Tue Sep 12, 2023 13 Projections for 2023 (Part 9)

A collection of projections for political world maps
(see Intro for further explanations)

September: Canters W13

Canters W13
Creator Frank Canters (1989)
Group Lenticular
Property Compromise
Other Names
  • Canters Polyconic 1989 f8
  • Low-error polyconic projection with twofold symmetry and equally spaced parallels
Remarks Please regard Naming Canters’ Projections. Also see my blogpost about the Canters projections, part 1 (W01 - W14) and part 2 (W15 - W34).

Again, I can keep this blogpost very short: I covered the Canters projections in 2021 in a two-part article, and there, I already pointed out that the W13 is similar to the Winkel Tripel. However, it has better overall distortion values, not only by Canters’ own metric, but (as far as I know) also by the Airy-Kavraiskiy and the Jordan-Kavraiskiy criteria and the Goldberg-Gott metric.

So if you like the Winkel Tripel but want some improvement in the distribution of distortion – or just a little variety – the Canters W13 is a good choice. In case you are bothered by the look of the pole line … well, sigh, there’s always the option to truncate the map without dismissing something that’s really important. I wouldn’t recommend this, but of course I generally don’t mind curved pole lines.

As for the OGABO version and the plagal aspect – they look good and highly usable:

So – after three months with very ordinary-looking projections, we’ll have a “daring” one in October.
See you!

"Angle triple"? Is this a machine translation fail?
