The Area Target Object
The Area Target object models a region on the surface of the central body. Select one or more of the following to model an Area Target and impose constraints:
The boundary of an area target extends infinitely and geodetically above the ellipsoid when used in Access calculations.
Basic Properties
| Property | Description |
|---|---|
| Boundary | Define the area target as a pattern bound by selected points or as an ellipse with specified parameters. |
| Centroid | Define a 'center' point for the area target to be used as, among other things, a terminal point for access lines drawn to the area target during animation. |
| Description | Record useful information about the area target. |
2D Graphics Properties
| Property | Description |
|---|---|
| Attributes | Define color, line style and other graphics characteristics for the area target, and opt whether to inherit or override global attributes defined at the Scenario level. |
| Display Times | Set time intervals during which area target graphics display. |
3D Graphics Properties
| Property | Description |
|---|---|
| Attributes | Define color, line style and other graphics characteristics for the area target, and opt whether to inherit or override attributes defined at the 2D Graphics level. |
| Vector | Control the display of vectors and other geometric elements related to the line target. |
Constraints
| Property | Description |
|---|---|
| Basic | Impose minimum elevation and line-of-sight constraints on access from an area target to another object. |
| Temporal | Impose time-based access constraints from an area target to another object. |
| Vector | Constrain access computations with respect to any valid vector or angle. |
