Unit of radius about nayuki-web-published-code HOT 5 CLOSED

The smallest enclosing circle algorithm is only appropriate for a flat Euclidean plane. It is not suitable, in any way, shape, or form, for the surface of a sphere (Earth), latitude-longitude coordinates, etc.

Your question is beyond the scope of my work. You should ask on a forum like Stack Overflow, GIS Stack Exchange, etc.

In case of a flat euclidean plane. what would be the presumed unit of radius in this case?

from nayuki-web-published-code.

I treated it as decimal degrees and used the simple conversion supposing value to be at equator.
radius * 111.32 and rounded the value upto two decimal places to get a kilometer result.
gave me near accurate results although theoretically its not supposed to work 😆

Hi, I agree with the point you made regarding the applicability of the smallest enclosing circle algorithm only for the flat Euclidean plane. I still think if the geo points are "close enough" the use of this algorithm might make sense. However, for avoiding further confusion I recommend that you mention this on your website and remove the example/make a note on the slides on facility location example.

The PDF slides are from some random university and are not made by me. I will not be editing the examples.
