Goldberg & Gott (2008) developed six error measures to rate flat map projections on their verisimilitude to the sphere: Isotropy, Area, Flexion, Skewness, Distances, and Boundary Cuts. The first two depend on the metric of the projection, the next two on its first derivatives. By these criteria, the Winkel Tripel (used by National Geographic for world maps) was the best scoring of all the known projections with a sum of squares of the six errors of 4.563, normalized relative to the…

TLDR
Since the impact of distortion for global-scale mapping is the most challenging, I will focus on what makes maps work (or not), and some solutions, at this scale.
High fidelity fiber orientation density functions from fiber ball imaging
TLDR
Requirements for the construction of high fidelity fODFs, in the sense of having good angular resolution, adequate data to avoid sampling errors, and minimal noise artifacts, are described for fODF calculated with fiber ball imaging.

Part 2: Distortion-Spectrum Applications Projection Cross-breeding
TLDR
The concept of projection cross-breeding is introduced as a technique of mixing two or more 'parent' MCME projections selected from the MCME Atlas in order to produce an 'offspring' projection that minimizes cartographic distortions and inherits the most desirable cartographic characteristics for the specific data-mapping task.
