Now let’s talk about bird spikes. You may have seen these on electric signs for businesses. These are usually for smaller birds. They come in plastic or stainless steel. They may not be very good for geese landing on your lawn or parking lot but they can be affective for roofs. If you have flat areas where these pests like to hang out you can lay spikes down to deter them. I would recommend the stainless steel spikes to avoid breakage.

Bird spikes might not be effective in your quest to shoo away geese but I put them in here as a possible idea that could be modified for your specific situation.
