Hi and thanks a lot for this great library - it is really helpful!
I have found and issue with the caclulation of centroids for some polygons.
In some cases the centroid is calculated wrongly: It returns the correct position but with a wrong algebraic sign.
For example:
"geometry":{"type":"Polygon","coordinates":[[[11.504408,48.5300738],[11.5043411,48.5298856],[11.5045044,48.5298578],[11.5045017,48.5298478],[11.5045637,48.5298367],[11.5045684,48.5298463],[11.5046393,48.5298347],[11.5046361,48.5298246],[11.5047081,48.5298117],[11.5047115,48.5298221],[11.504932,48.529786],[11.5049734,48.5297792],[11.5049843,48.5298138],[11.5049874,48.5298132],[11.5049908,48.5298222],[11.5050429,48.529814],[11.5050458,48.5298037],[11.5050587,48.5298057],[11.5050564,48.5298166],[11.5050881,48.5298351],[11.5050994,48.5298276],[11.5051079,48.5298343],[11.5050971,48.529842],[11.5051094,48.5298702],[11.5051246,48.5298705],[11.5051236,48.5298803],[11.5051092,48.5298804],[11.5050929,48.529905],[11.5051034,48.5299119],[11.505095,48.5299183],[11.505084,48.5299115],[11.5050372,48.5299177],[11.5050653,48.5299939],[11.5049485,48.5300126],[11.5049373,48.5299829],[11.5047937,48.5300075],[11.5047977,48.5300183],[11.5047108,48.5300322],[11.5047074,48.5300221],[11.5046331,48.5300348],[11.5046361,48.5300432],[11.50458,48.5300531],[11.5045767,48.5300445],[11.5044831,48.5300607],[11.504408,48.5300738]]]}
returns:
[0]: -11.504723502784723 [1]: -48.52992432037955
It would be great if this issue could be fixed.
Thank you for reporting this issue. I have addressed the algebraic sign problem in the centroid calculation for specific polygons. The fix has been implemented and published in the latest release v2.2.1. Please update to the latest version, and let me know if the issue persists. Your feedback is greatly appreciated!
Hey, thanks you sooo much for your quick reaction! I can confirm that the centroid is now calculated corretly! Five stars! :-)
