The example loads a Landsat 8 panchromatic band image, calculates the X and Y gradients, then determines the gradient's magnitude by combining the squared X and Y values and the gradient's direction using `atan2` function. Finally, it displays the gradient and its direction, centered on San Francisco. The image gradient magnitude is then illustrated.\n"]]
