Zone Constraints

Zones Constraints allow you to define areas where access is or is not allowed using inclusion and exclusion zones.

If a constraint is not available for accesses from an object, it will be disabled (grayed out) in the Constraints properties page for that object.

When an access involves a child object (i.e., sensor, transmitter, receiver, antenna, or radar), use the child object's parent or grandparent in the table below to determine whether the constraint can be used for access to that child object. For example, if a constraint can be used for accesses to all vehicles, then that constraint can also be used for any child object of a vehicle.

Constraint Description Constraint used for accesses to...
Exclusion Zone Use the options in the Exclusion Zones area to specify regions that should be excluded from access calculations. Values set here serve as the perimeter points for the zone to be excluded. An exclusion zone is formed on the basis of the values entered. F, T, Pl, V, P, St, AT, LT
Inclusion Zone The Inclusion Zone area can be used to define a region that will be included in access calculations, to the exclusion of all other regions. You can only have one inclusion zone constraint for an object. F, T, Pl, V, P, St, AT, LT
Latitude

This option is available because of backward compatibility needs. We suggest you use the options in the Inclusion Zone area to specify latitude bounds.

Use the options in the Latitude area to indicate latitude boundaries. You can specify a latitude boundary within which accesses to the vehicle must fall in order to be valid. If ON, specify the Minimum and Maximum latitude values to define the latitude boundary.

 F, T, Pl, V, P, St, AT, LT

Add Exclusion Zones

To define regions to be excluded from access calculations:

  1. Click Add.
  2. Enter the Minimum Latitude and Longitude that will define the exclusion region.
  3. Enter the Maximum Latitude and Longitude that will define the exclusion region.
  4. Repeat steps 1-3 to add as many zones as necessary.
  5. Click OK or Apply to save your changes.

Use the slider to switch among zones. The value to the left of the slider is a sequential identifier assigned to that zone definition.

Delete Exclusion Zones

To remove an exclusion zone:

  1. Use the slider to select the zone of interest.
  2. Click Delete to the right of the slider.
  3. Click OK or Apply to save your changes.

Set an Inclusion Zone

To define a region to be included in access calculations:

  1. Select the Use check box.
  2. Enter the Minimum Latitude and Longitude that will define the inclusion region.
  3. Enter the Maximum Latitude and Longitude that will define the inclusion region.
  4. Click OK or Apply to save your changes.

You can change the Minimum and Maximum settings at will, though the changes will not be reflected in your scenario until you click OK or Apply. To turn off the inclusion zone, clear the Use check box.
