I tell ya ayeball. What WGT is doing is state of the art. Thousands of pictures of each course are required. They even use a helicopter with high speed cameras to get all the high elevation shots we get from different cams.
Then GPS finders are placed all over the course providing unheard of accuracy in elevation details. It's done even finer on the greens. I read once that the elevations on the greens are within an inch or so. Now all these images have to be lined up with that elevation detail.
This has never been done before. I can only imagine the time it takes to give us these high definition courses. I too really want to see more. I want them to stay in business as long as possible. It has to be a real hairy balancing act.
