I am trying to make an IDW-interpolation in arcgis 10.1.
In my sample file i have points with the same x,y and z values. According the arcgis-resource-site, the points are considered duplicates and have no effect on the output.
However, i want these points to have an effect:
the more often a certain value has been observed in a location, the more important that z-value should be.
Is there a way to circumvent this ignoring of duplicate sample points, or to use the number of duplicate points as a 'weight-value' to indicate relative importance of sample points?
