GPS (Global Positioning System) is a helpful tool used to identify the borders of a wildfire and help scientists predict how far the wildfire will spread. GPS can be used to track the location of firefighting equipment and personnel, map the extent of the fire, and model the fire's behavior based on terrain and weather data. This positioning data is crucial for creating accurate maps and projections of wildfire movement.
