I am still a beginner with GIS.
I can't find an easy way to get a maximum distance from multiple points.
I have a layer of up to 100 points (without a unique ID - maybe that is part of the problem? but I could easily add that) and I want to get the length of maximum distance between any two of them.
I tried plenty of line-points plugins, but nothing seems to work, I also tried to make a minimum convex polygon (basically convex hull of all the points) and get a diagonal of that but failed in all tries again.
How do I do this without using a programming language?
I am using QGIS 2.18.5
