Geometry Uncertainty Computation
Geometry Relationships offer the ability to compute uncertainty using the uncertainty of the points included in the relationship. In order to compute uncertainty perform the following steps:
-
Ensure that all of the points included in the GR feature have uncertainty fields computed. This can be done by using the function Create Point Uncertainty Fields on the Alignments tab.
-
In the relationship properties check the Uncertainty check box and then press Compute. This will ask you for the number of samples to use and generate the uncertainty event, as well as adding the uncertainty statistics to the related GR Criteria
Once uncertainty has been computed for a relationship the relation- ship is put into a Dormant status. This is done so that the uncertainty values are not removed as part of the normal recomputation process of a relationship. At any time the dormant status can be removed through the right-click option Set/Clear Relationship Dormant Status.
