Hi Totò,

There are two constrains related do sliver polygons:
- Maximum thinness
- Max. area

The value should be the one failing the condition for the feature. Can be one of the two. The enum ValueType (defined in src/analysis/vector/geometry_checker/qgsgeometrycheckerror.cpp) is not exposed, so there is no explicit information about it.

I hope it helps.

What does the real value of Sliver polygon represent?
- it's not the area of the polygon
- it's not the perimeter
- is not the area of the bounding box

so I ask if anyone can tell me what it represents, I can't find anything useful in the documentation.


Thank you
