Hi, We have a new forum, and questions should be best addressed here if possible :
https://forum.orfeo-toolbox.org/ Regarding your question, we have an issue running on this topic, it should be fixed in a near future. https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/issues/1798 Regards, Julien De : otb-users@googlegroups.com <otb-users@googlegroups.com> De la part de Julien Radoux Envoyé : vendredi 1 février 2019 07:34 À : otb-users <otb-users@googlegroups.com> Objet : [otb-users] Re: Is there any way to make Band Math ignore NA values? hi, the workaround is quite heavy but works most of the case : testing that you value are within a range: it wold be something like (((im1b1>-9999)and(im1b1<9999)?im1b1:0) + (((im2b1>-9999)and(im2b1<9999))?im2b1) + .... if this does not work straight aways, try first with a gdalbuildvrt -vrtnodata None Le jeudi 31 janvier 2019 22:39:22 UTC+1, Álvaro Paredes a écrit : Hi everyone, I'm using otb BandMath to calculate some stats through several images, and the problem that arises is that nodata values from the images are interfering with results. Every image is a geotif of the same extent and resolution, but the location of the NAs values are variable (due to clouds principally). If I compute the sum or average of the images I end with and image full of NAs, without any valid value (in all the images, there's at least one cell with NAs). For example, I'm running: otbcli_BandMath -il im1.tif im2.tif im3.tifim4.tif im5.tif im6.tif im7.tif im8.tif im9.tif im10.tif -out test.tif -exp "(im1b1+im2b1+im3b1+im4b1+im5b1+im6b1+im7b1+im8b1+im9b1+im10b1)" Is there any way to tell to the program to ignore nodata values or is there a workaround to solve it?
