Set NoData value for pixels outside a region in a GeoTIFF

Hi ​@gbcfgeo2025 ,

I checked the GeoTIFF raster you shared with FME, and found that Nodata is defined already, as shown in the screenshot below. Isn't this Nodata definition what you required?

Yes, how can I assign a value of 0 or, for example, -10 to the NoData pixels? Can I set a non-existent (empty) value?

You can use RasterBandNodataSetter (Replace Cell Values: Yes) to assign a new Nodata value to the current Nodata pixels. However, the new Nodata value should be 0 or greater, since the band interpretation is GRAY16 (unsigned 16 bit integer). i.e. -10 is not available.
