  Canters W30 Canters W30/UE (non-optimized)
Creator Frank Canters (2002) Frank Canters, Tobias Jung (2021 / 2002)
Group Lenticular Lenticular
Property Equal-area Equal-area
Other Names
  • Low-error equal-area transformation of Hammer-Wagner [Wagner VII] with twofold symmetry and correct ratio of the axes
Remarks Please regard Naming Canters’ Projections. Also see my blogpost about the Canters projections, part 1 (W01 - W14) and part 2 (W15 - W34). An umbezifferte (renumbered), equal-area variant of Canters W30.
Please note that in contrast to Canters’ original projections, it has not been optimized for low distortion values.

Using the Böhm notation, this would be the Canters W30 90-150-60-0-200. Also see my blogpost.
