I am working on optimizing an existing monitoring well network in ArcGIS as part of my master thesis. I successfully used the tool “Densify Sampling Network” for adding measurement locations to parts of the study area with a high kriging standard error. However I can’t manage to use the tool for the reduction of measurement locations for those parts of the study area where they have the least influence on the predictions. I keep receiving "Error 040043: Measurement error for data with coincident samples should not be equal to zero." (As parameters I used number_output_points: 5 and in_candidate_point_features: point feature class containing all 137 monitoring wells). What am I doing wrong?
Thanks for your help in advance.
