I have changed the No Data of a raster Forest.asc into No data = 0 using Raster -> Conversion -> Translate option in QGIS. So, when I add the output raster layer Forest_1.asc in QGIS and check for the minimum pixel value, it is showing that Minimum = 1 and Maximum = 3. But, when I open this Forest_1.asc in TextPad and read the values, I can see that it is written that No Data Value = 0. But, I am not able to find any zero as pixel value in the ascii file. I can find only 1 and 3 as pixel value in ascii file.
How can I solve this issue ?
