Model builder - automatic selection of quantiles for raster data

KarolinaKorzeniowska

I would like to find values of quantile 5% and quantile 95% of my data. I know that I can find statistics using Get Raster Properties; but there is no possibility to get the quantile values of the data. Finally I have found the quantile values using Reclassify option. I reclassified my data for three classes using Quantile as a method for classification with thresholds: 5, 95, and 100%

However, here I have a problem, because I would like to apply the evaluated quantiles in Model Builder am when I change the input data I have to evaluate the qauntiles every time manually, because model builder is not doing this automatically. Is there some other way to evaluate quantiles which can be fully automatically used in Model Builder?

Thanks in advance for some suggestions.

NoData values should be converted to None, according to the doc.  I'd try this with a small dataset at the python prompt and look at the array on the numpy side to see if things are what you think they are.

Quantile breaks can be unexpected when there are a lot ties (many cells with the same value) in your data.
