Description
Using Master 5ed164a
This seems like quite a bad one because it appears to work but actually doesn't give feedback that its not or why not.
The following expression does "work" - it passes "expression valid" and the layer names are correct (I double-clicked them):
((IR SP1874@1 - RGB SP1874@1) / (IR SP1874@1 + RGB SP1874@1))
The problem is, the output result is "0" across the board.
To actually get a proper NDVI result, I need to rename my layers and use this:
((IRSP1874@1 - RGBSP1874@1) / (IRSP1874@1 + RGBSP1874@1))
So its not working when layers have spaces in their names.
