I am trying to create 3 random points with a minimum separation of 75 meters within each polygon of the attached shape file. I am using Sampling -> Create Random Points
The tool runs to completion with no error messages. However, upon inspection, many of the polygons contain 2 points, not 3.
Any thoughts?
Basically those types of algorithms will fit as many as they can within the number of tries it is given and will get as close as it can given the spatial area that it has to work with.
In short... it may try 100 combinations to fit 3 in... each time it fails only producing 1 or 2... then it gives up
Your options...
I have written a similar toolset that does the same thing,
Point Tools for Pro … # 7
but I likewise tried to get as close as possible to the target number within what I considered a reasonable period of time. Beyond that... the user can plunk in a point themselves if they can find a fit.
Thanks Dan. The weird thing is that it doesn't throw an error. If I increase the inter-point spacing from 75m to 100m, it then throws an error. 3rd party tools such as ETGeowizards don't seem to have any trouble placing 3 random points per grid with the 75m inter-point spacing.
100 means that it didn't work
Maybe Ianko's toolbox tries harder to get the job done
