Hello,
I have multiple overlapping rasters (DEM) that I want to merge together using "Mosaic to new Raster". One raster has some noisy spots that I want to set to NoData, to be ignored in the final DEM.
How can I do that using polygons that mask the areas i want to delete?
The SetNull function is always setting everything BUT the area to NoData when i use an extracted raster as the condition...
Cheers
Are you following this procedure?
If it is masking everything but what you want, then you have to reverse the condition.
Perhaps you might want to show your steps and perhaps a sample image of where the problem lies.
- I created a polygon with the area i want to setNull
- extract by mask to these areas
The output is everywhere NoData exept for the area I want to setNull. If I use this raster as a condition the NoData areas will always be true and result in NoData...
You have your mask and you can use con and setnull to assign nodata to your mask cells

I solved the problem.
