Hello, I am trying to generate a predetermined number of systematically located sample points across multiple polygons.

I have been able to create randomly sampled points using Create Spatial Sampling Locations tool stratified by polygon and setting Strata Sample Count Allocation Method to a population field.

However, I cannot see how to achieve systematic sampling within each polygon.

Any advice appreciated, thanks.

What parameters are you using in the tool?

Thanks for the response Dan. The below settings look to do what I need but with random rather than systematic sampling.

Input Study Area: woodland polygon layer

Output Features: default

Sample Method: Stratified by individual polygon

Strata Sample Count Allocation Method: Count equal to population field

Population Field: Plots (number of plots per polygon)

Minimum Distance Between Sample Plots: default 0

Not sure, but looking at the parameters, I suspect some of the "optional" parameters are only available depending upon the sampling method chosen and not available for others

I created the Sampling Design Tool add-in for doing more complex sampling. Take a look at its documentation to see if it has the capability to do what you're wanting.
