The Mercator projection is created by projecting the globe onto a cylinder whose center follows the Earth’s rotation axis. Most of the math here can also be applies to Mercator, where the scale reductions are applied to Y instead of X. It’s fairly accurate to measure from point to point within small distances and close to the meridian, so this post is based on that. The UTM projection is one of the most commonly used projections. creating a new projection for each point, do the math in spherical coordinate systems etc, but none of them are completely trivial. In many cases a “normal” circle is sufficient for accuracy, but still it got me thinking how I would do this 100% accurate. If you’re lucky, you’ll have an ellipse but often they get even more complex than this. All map projections adds distortion so you rarely end up with a circle. Recently a friend of mine asked me what projection would be the best to create point-buffer circles.
