John,
A drone and aerial photography have so many benefits to the game of golf, here are 3 examples of why drone photography can be beneficial.
Example 1: Showcasing an architectural feature
I wrote an article about Tillinghast's Great Hazard, the best way to truly understand the feature is drone footage, it allows an unfamiliar student of architecture to visually seen the magnitude of this architectural feature.
Example 2:An Unseen factor
Here's a photo of Loblolly, its a course that is a couple hundred yards from the Ocean but you would never know that it was there. Thus when its windy its really tough but many wonder why it gets so windy there. Without this photo from a drone, you would never know that its so close.
Example 3: Explaining Width and playability
Aerial photos allow for comparison in width of different courses and different holes. GC of Houston's best hole is the short par 4 12th, is it possible because it is the widest and allows for options, different playing angles and strategy? Look at how wide it is versus the long and narrow par 4 11th coming the other way?
I will eagerly awaiting your response and attempt to debunk the validity of the benefits of drone and aerial photography that I have laid out above.
