Cell Statistics "ignore nodata values" is not working

Discussion created by k.blauvetl on Sep 25, 2012

I have 12 geotiff rasters of the U.S., and I am trying to calculate a mean, median, max, and min raster from those 12 using cell statistics. There are some nodata values inside each raster, and I want the calculations to ignore these values (if the value of a pixel in each raster is: 7, 2, 4, 3, nodata, 1, 4, 2, nodata, 3, 1, nodata, then I would want the mean to be 9. Instead, if there is a nodata value in any of the 12 raster's, the output raster produces a nodata value. I have tried selecting the "ignore no data values" in cell statistics, but there is no difference; the output always produces a nodata value if there are any in the input rasters. I was wondering if anyone else had this issue, or if I am doing something wrong in the formatting of the nodata values.

Thank you!
