Validation (KB11)

kb11_validation = Validation(traces, area, name=name, allow_fix=True)

# Run actual validation and capture the outputted validated trace GeoDataFrame
kb11_validated = kb11_validation.run_validation()

Validation results (KB11)

describe_results(kb11_validated, kb11_validation.ERROR_COLUMN)

Out of 707 traces, 1 were invalid.

There were 1 error types. These were:
SHARP TURNS

The KB11 dataset only contains SHARP TURNS errors which are normally non-disruptive in further analyses.
