random point in a circle centred in a geographical position
Dear List members
I am trying to find a way to generate a random point in a circle centred in a geographical location.
So far I have used the following formula (see code below):
random_x = original_x + radius*cos(angle)
random_y = original_y + radius*sin(angle)
where radius is a random number between 0 and the radius of the circle and
angle is between 0 and 360 degrees
The code bellow works
