Anyone thought of/already trying to use the LiDAR functionality of the new iPhone in an architectural/Course study context?

Looks utterly awesome - might have to give up on my Apple aversion...

   Seems a good ploy to sell more memory capacity phones...

There's an awful lot of data required for that . . . if they can build that all into the Phone, I will be amazed.

Might have to upgrade to the iPad Pro to do it -- I'd be shocked if we don't see Bryson playing practice rounds with one.

Buck:


I know, but a normal-sized putting green is twice as big as my house, and you need detail down to the inch if the scan is going to be useful.  That's a lot of data.

The 12's come with up to 256 GB of storage.  That's quite a bit actually especially if using compression...

Tom-
My point was really more that the USGA better get in front of this or it'll be another area where they are playing catch-up with technology. The way I understand it, with 5G device storage is going to be almost meaningless -- load it right to AWS. If not now it won't be long.

Looks like typical LAS format files, which LIDAR uses, are 500 MB.  Scanning and saving 18 greens to upload to the cloud later would only use approx 10 GB of storage on the phone, which is nothing...

Pretty sure the USGA/R&A ruling covered scale so the level of detail was dialed back. Whether it’s on a phone or sheet of paper doesn’t seem like it would matter, does it?

Oh it absolutely matters.  If you're on a screen there is no such thing as scale, you can enlarge the diagram as big as you want with two fingers, and if all the detail is there on the contours, you can read it much more easily.  The USGA's ruling was that you can only use a printed book, where the limitation on size makes it harder to read every little contour.


[I found it very funny that their scale restriction for the map of a green was 3/8 " to 5 yards . . . it took me a minute to translate that to how anyone with a planning or engineering degree would describe the scale, which is 1 inch = 40 feet.

   Reminds me of a Ross quote, i remember:  "golfers used to be made on the course, now they're made in the machine shop"  i don't think he was enamored of technology...


i suppose the green topo data could be used in gps glasses, projecting a blue line path to the hole for robo-golfer, or at least to line up Shivas' fabled cheater line...  i guess if you're that in need of help, go for it

The interpretation prohibits apps which can scale beyond the allowable size.

In electronic or digital form, any image of a putting green must meet the above scale and size limits. Even when an electronic or digital putting green map meets the above limits, the player is still in breach of Rule 4.3 if the player uses any device in a manner not consistent with the purpose of these limits, such as by:[/color]- Increasing the size of the green’s representation beyond the scale or size limits;[/color]- Producing a recommended line of play based on the location (or estimated location) of the player’s ball (see Rule 4.3a(1)).

The new green apps that use laser technology all now have versions that allow you to pinch and enlarge and zoom in/out, etc. and then you just click a button for the tournament-legal version. The tournament legal ones are still helpful, but barely. They are helpful on long putts and chips/pitches, but definitely not very helpful on "birdie-length" putts, if that makes sense. There just isn't enough detail allowed by the rules now -- which is a very good thing.
