How to find different (Errors)in two polygon layers

Two polygon layers shapefile
valid 3 meter criteria

Can you describe the issue you are trying to solve in more details?

I have 2 polygon shape file layers
both layers present in same location but some where one polygon not matched with 2nd layer polygon
So we need that error only as an output.

You could use Shapely, a geometry library, to describe your polygons. Then, shapely.difference can tell you where your polygons do not overlap.

What data format are your polygons in?

Shape file.

You’re going to need to be more specific.
