A job perimeter is a polygon feature class that controls the spatial area in which modifications are allowed for a specific job. Perimeters are mainly for Survey applications, but you can use them for any job.
The perimeter feature class stores the job perimeter of the respective jobs. Assign a polygon feature class that is used only for perimeters. If necessary, create a polygon feature class for that purpose.
You can define feature rules to apply to the objects within a perimeter, such as a perimeter check. If you assign a perimeter feature class, the Perimeter Check feature rule is activated automatically. This is a predefined server-side feature rule. It checks whether a feature is inside the selected perimeter.
