Argentina Project has been refactored/augmented.
RHMSD is illustrated, works fine for creating image.
Otherwise of NO use for contour plot.
May have interest associated with 3D Spline(m,x,y).
User grid may be interesting for Publishing.
Welcome for more applications.
Take care ... Jean.

We had a freak hail storm in our northern suburbs, some growers lost their produce, sad.

I have worked with protection and control secondary systems, all my working life, there are some similarities to your Process Control and Instrumentation.
