# 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.

The image above illustrates the obstacle shapes available in AeroGCS GREEN, which include two main types: **Polygon** and **Circle**. If you choose not to proceed with creating an obstacle, simply click the "**Cancel**" button to exit the obstacle selection.
