Feature Analyst: Flat Feature

The Flat Feature analysis function allows the user to test that the feature Delta Z (MaxZ – MinZ) is less than the specified Z tolerance range. By default the value is 0, but the user can specify the tolerance value when activating this function in the Feature Analyst Options dialog. This is useful for quickly determining whether a feature, such as a water body, is flat with no z-value errors.

Feature Analyst Options – Enabling Flat Feature analysis

Once setup, a column will appear that, once analysis is run, will show a green check if the feature passes the tolerance range and a red x if the feature does not pass. This test is pass/fail for an entire feature. To pass, the difference between the Min and Max vertex z-values must fit within the specified tolerance.
