Sure! It's pretty straightforward actually. The first approach (which is a simplification) uses the usual way to calculate a distance between two points on a FLAT plane, which using is the Pythagorean Theorem. So d = √((y1 - y2)^2 + (x

Same here, we use GeoJSON for floor plans and it works great. Yeah, too bad that Turf is geographical only, but it still has some nice helpers that are agnostic to the shape of the plane.

Hey, that was the idea for the next article...

Indeed, I added a couple of paragraphs in the end explaining the difference and the actual results. As a side note, I actually got slightly different numbers, but maybe that's because of the lower quality of data that I used.

I've actually added this to the article, thank you again!

You're correct, this is just a synthetic value used to rank the distances.

Damn, this is a great point, thank you!

That is correct, but - as pointed in the article - we work on floor plans, which are flat, so I wanted to simplify this a bit to not create too much issues to solve in one article. That said, it was probably an oversimplification, since act

Impressive, thank you for sharing!

Indeed, but the convex hull approach also works for multiple sets of points, in any order. As for [2], in the article the data is separated into 16 polygons, so the interior lines are actually shared between polygons. It's still possib
