I am trying to get a certain expression in QGIS right, but because I am quite new to QGIS expressions, I cannot quite get it right.
Basically I want another field, to have specific kind of text based on the value of the pre-existing field. In this case, when the height of a tree ("Height" field) has the following values, the following text will be displayed:
- <6 meters: >6 meters 3rd category
- between 6-12 meters: 2nd category
- >12 meters: 1st category
How exactly do I do this and what I am doing wrong here?
As for a side note, should I better do this using AutoFields plugin, so I am sure it happens automatically?
