Validation¶

Validation allows you to check your data source and helps to identify features which do not conform to the test(s) you specify.

• Select a layer from the Layers View and go to Operations ‣ Validation...
• Select a test (*Is Valid Geometry for example*) from the list and click New to create the new test.
• Customize your test and click Run

Each feature in the current layer will be validated to ensure it passes each test. Features which fail a test will be displayed in the Issues List, which appears if at least one feature fails a validation.

Available tests:

• Is Valid Geometry: the feature conforms to its own geometry specification
• NameExists
• Line Not Self Intersection: LineStrings do not intersect self
• Line Not Self Overlapping: LineStrings do not overlap self
• Line Without Dangles
• UniqueFID: FID is unique
