Hi,

 

 

I want to do a geographic analysis on height. Some cell values however are filtered out because of trees, etc and set to No Data. For this reason I want to change the no data values(brown) to the average of surrounding band values (green). I tried using the rasterConvolver, without success. Also I tried all these steps (https://knowledge.safe.com/questions/3796/fill-raster-nodata-values-with-minmaxaverage-value.html ) , also without luck, since I guess it requires a more profound understanding of FME.

 

 

Any help much appreciated!

Hi @ymor_v,

 

From your post it looks like you are using point data and not rasters, that could be the reason why the RasterConvolver doesn't work.

thanks @itay, if I use the raster itself, how do I merge the two sets (the original and the rasterconvolver output). What expression can I use so that the rasterconvolver output only replaces the no data of the original ?

 

 

thanks !!
