Issues with land cover classification

[bweeding]

Hi all, I'm trying to use the land cover reclassifier on the attached .tif file:

However, when I attempt to use the classifier, I receive the following error:

Any suggestions as to what I'm doing wrong would be greatly appreciated!

You need to fill in numbers in the "greater than" column also. Your screen dump show that this column is empty.

I have now done this and it is generating the landcover file. However, when I attempt to run the model using the file, I receive the error:

QgsProcessingException: Error in land cover grid: Land cover grid includes Confier land cover class. Ground cover information (underneath canopy) is required.

How do I go about generating the ground cover information under the canopy?

Cheers

Well, when deriving land cover from lidar data this is a decission you need to do without knowing what is actually underneath. I usually reclass tress to bare soil which is the most common lc under a tree. However, is some cases there could be grass or paved. You simply have to make a judgement.

Ah ok cool. How do I tell the model what I have decided? With a separate TIF file?

Just reclassify your conifer and deciduous to e.g. Bare soil

Ah so the trees are only represented in the cdsm, not in the land cover?

Correct. Land cover represent what material is on the ground, underneath the trees.

Ah excellent, I've got it working now! Thank you.
