median filter results in "ribbon" around raster

Question

When I run a median focal filter using a large circular neighbourhood area (approx. > 1/5 of raster extent) the result is a "ribbon" around the raster with an empty middle (nodata values). Not the case when running other stats. At what point does the calculation of the median returns Nodata and what would be the max. neighbourhood extent?

cheers,

Javier

Hello Javier.

I know this is an old issue, but I was going through the archives for another purpose, and thought I could provide an update for this one in case you might still be interested.

If you have access to ArcGIS Pro 2.3 or later, this issue should be resolved.  Please reach out to me here or to your Support contact if you have any further questions.

Cheers,

Juan
