I have checked the coincidence of data points with different values and it happens in a few cases somewhere else in the area but in those cases the resulting grid is approximated to the average of those points. I appreciate the suggestions to evaluate other methods and I have actually done it but I like the "control" we have in terms of restricting the extension of the search radius and having those cells with null values where there is no data while the other methods still interpolate over those areas. Perhaps I could just use one of those and build a buffering mask to clip the result. Independent of that, I still wonder why this abnormal high values show up.  ... View more

As I understand it, IDW would extend the search radius if no data points are found within the specified search distance. Is not clear to me why there is a higher cell value with surrounding cells that are either lower than the 353 outlier or null values. ... View more

Thanks Adrian for your prompt answer. I tried with IDW variable distance, krigging, and natural neighbor from the SA, and IDW standard circular with a radius of 4000 from the Geostatistical Analyst, always keeping the same cell size (1,000 m) and these methods do not show that behavior. It seems to be happening only with IDW fixed distance. It also happens at some boundary cells, where there are no more data points, as in the illustration included. Is that weird or explainable? ...
