How is the Point on surface tool calculated in QGIS

by AWGIS   Last Updated June 13, 2019 10:22 AM

I am interested to know how the Point on surface tool works in QGIS 3. I am choosing to use this rather than the Centroids tool which works of the "center of mass" methodology because this creates a point outside the area of the polygon which is not suitable for my needs.

The QGIS documentation does not seem to explain the calculation used but I would like to know so I can test whether it is suitable for my analysis and so I can incorporate an error with my calculations.
