I am doing the infamous qgistutorials:
Two raster layers (converted from vector to raster) having ("pseudo") band values 0 and 1, were added up with
+in the raster calculator.
This resulted in a "merged raster" with values 0, 1, 2; with 2 being the cross section of two 1s of the input rasters.
To remove the 2, the merged raster was put into the raster calculator. again with the expression
merged raster > 0.
As a result the latest raster has only 0, 1, (and the cross-section 2 was not represented in the raster image anymore).
Here is, where I have problems with comprehension. What does the calculator do in the last step?
I know that
> is a bigger sign. But would not it take all the values from the
raster > 0, i.e. take 1 and 2 and remove 0 information?
