The AddSpeedZoneForCoord function is used to add a speed zone to a specific set of coordinates. This function is typically used in GPS applications and can be very helpful for tracking vehicle speed and ensuring that drivers are staying within a designated speed limit.
AddSpeedZoneForCoord(latitude: Float, longitude: Float, radius: Float, speedLimit: Float)
The AddSpeedZoneForCoord function takes in four parameters:
latitude: The latitude of the coordinate where the speed zone should be added.
longitude: The longitude of the coordinate where the speed zone should be added.
radius: The radius of the speed zone in meters.
speedLimit: The speed limit for the speed zone in meters per second.
The AddSpeedZoneForCoord function does not return any value. Instead, it adds a speed zone to the specified set of coordinates.
AddSpeedZoneForCoord(37.7749, -122.4194, 100, 20)
This function call would add a speed zone to the coordinates (37.7749, -122.4194) with a radius of 100 meters and a speed limit of 20 meters per second.
The AddSpeedZoneForCoord function is an essential tool for developers who need to track vehicle speed and ensure that drivers are adhering to speed limits. By providing a simple and straightforward way to add speed zones to specific coordinates, this function makes it easy for developers to implement GPS-based speed tracking in their applications.
