With QGIS 2.14.3 I am attempting to convert a raster layer to a binary layer, using a certain threshold. With some layers I can use this formula in the Raster Calculator and get the expected output;
"raster@1" < 0.994 = 0 AND "raster@1" > 0.994 = 1
But when I try it with another layer the output is either all
nan or all
0's. I've tried saving it in a different format (.img instead of .tif) as suggested in another answer here, but get the same result.
Is there a mistake I'm making with this?
Or an obvious reason it might give this output?
Or maybe the raster is just corrupted in some way?
(The imagery is the output from a long process, and confidential, so I can't share the actual file).
