Greetings friends:
I am working on lesson 7.3.5 in the User Guide / Manual (QGIS 3.10) –
Following along: Using the Raster Calculator.
I am having difficulty with the calculation formula as indicated below:
The manual states this formula should be used:
Aspect@1 <=90 OR Aspect@1 >= 270
Which I am assuming is incorrect because a) I get an error when I run it;
and b) when I set the parameters using the expression operators the formula
looks like this:
“Aspect@1” <=90 OR “Aspect@1” >=270
However, I still get the error:
Error parsing formula
Execution failed after 0.02 seconds
With some help – I then tried this formula
\“Aspect@1”\ <=90 OR \“Aspect@1”\ >=270
Which worked for this assignment.
However, moving on to lesson 7.3.6 – More criteria: which takes me to
21.12.2. Calculate slope (less than 2 and 5 degrees)
I get the same error as above again.
I am steadily working my way through the Manual and would appreciate any
help. I am using QGIS version 3.10.9-A Coruna (64 bit) on a Windows PC.
Thank you!
Wanda Norman
