I have to create Thiessen polygons with the spatially weighted averages for specific contaminate concentrations from different borings. I have the Thiessen polygons created but this only shows me the polygons based on the point locations not actually point concentration values that I would like. What tool can I use to get this info?
I only have ArcGIS free trial which limits the amount of tools I have access too. I also have QGIS and could use either to do solve the problem.
