I am using QGIS version 3.8.3-Zanzibar I have a shapefile and I want to compute the area by using Vector/Geometry tool/Add Geometry attributes.

Runnig this tool I get :

Feature (11) has invalid geometry. Please fix the geometry or change the Processing setting to the "Ignore invalid input features" option. Execution failed after 0.06 seconds

Any suggestion how to solve this?

Run the "Fix Geometries" processing algorithm against your data, and then try once again computing the area on the newly-generated temporary layer.

If it all looks good, save it out to a new shp or gpkg.

  • Thanks for your answer. Could you please let me know where to find the "Fix Geometries"?
