What aspect of aerial application is improved by using GPS technology?

Using GPS technology significantly enhances mapping and monitoring application areas in aerial applications. This technology allows for precise geographical positioning, which enables pilots to accurately navigate and target specific areas for pesticide application. With GPS, aerial applicators can create detailed maps indicating where pesticides have been applied, improving record-keeping and ensuring compliance with regulations. Additionally, real-time tracking helps in monitoring application rates and coverage, allowing operators to adjust their strategies as necessary for optimal results.

While the other aspects, such as fuel efficiency, speed of application, and coloration of spray, are important in aerial application, they do not directly stem from the primary benefits provided by GPS technology. The focus of this question is on the mapping and monitoring capabilities that GPS brings to the practice, making it a crucial tool for effective and responsible aerial pesticide application.
