# 12. Obstacle Avoidance

The **Obstacle Avoidance** function in AeroGCS GREEN is a powerful feature designed to prevent spraying in sensitive areas, such as wells, water reservoirs, and neighboring fields. To add obstacle points to an existing plot, navigate to the **Plot Creation** or **Plot Edit** screen and switch the "**Obstacle/Plot**" button to "**Obstacle**" mode. Once activated, a pop-up message will appear, prompting you to choose the preferred shape for the obstacle area. 

This functionality ensures safer and more precise operations, allowing you to avoid designated zones effectively.
