Evaluating the distortion and fit of candidate projections for globe gores
Following my earlier interest in globes and (now outdated) code to produce one - this repository provides the code and results of the first rigorous analysis pf the properties of a range of projections for use in globemaking.
distortion.py
contains library code for evaluating the projectionsglobe.py
contains the evaluation itselfmaps.py
simply produces a figure comparing the projections under consideration
This code allow you to evaluate the distortion properties (shown here for a 12-gore globe):
And the mathematical 'fit' of the globe to the sphere (shown here for a 12-gore globe):
For most purposes, this analysis demonstrates that the Cassini Projection is best suited to globe production.
