Jumpers could just make a few jumps anytime and send the video in that could be analyzed for distance. That would cut down on a lot of travel expense. -

This has nothing to do with that they are using at Worlds. -

I think it is time to do away with the long jump board altogether. Now with lasers and such, they can just measure the true distance of the jump from start to finish. Just have a one meter area that the jumper has to take off from. Getting rid of all those fouls would make the sport more exciting.
I actually think this would be good for the sport... you'd have to re-do all of the records, of course. -

1.) Congratulations Brittney! Her accomplishments often go relatively underpublicized.
2.) It alarms me that the measuring is being done this way. I feel like results can easily be manipulated or mis-recorded. Just wait for the long jump scandal where somebody jumps 8.96m, but computer sensors record it as 8.66m, and it's never ratified as a WR.
As mentioned above, world records would be confirmed with a steel tape. But some are questioning the accuracy of this system, a number of people feel that DeLoach was robbed on her last jump: https://twitter.com/iownabook/status/711206056546975744
They rake the pit almost immediately, well before the mark is displayed, not sure what recourse the athletes would have to protest an incorrect measurement. -
The USATF link provided talks about measuring from the stake. So, that doesn't tell us how a system automatically determines the location to measure.

We could also have competitions measuring how high somebody jumps without having a bar to clear or how far somebody throws something without having a sector to stay in or how fast somebody does 100 meters with a running start.
Eliminating some of the skill components would certainly require less athleticism and might therefore reduce some of the competitive thrill and appeal to those interested in the outcome of a meet.
... an old bloke guessing where to put his stick.
Phrasing! -

PVP or anyone, Sorry if I'm obtuse but could you post a link to the system they are using and specifically the part that explains how the closest point to the takeoff board (the landing point) is identified by that system.
Thank you -

It is linked and quoted up thread. Haven't had time to google the details on that system. Something about cameras. -

At a high school meet I was at a couple weeks ago, they pointed a laser from the side and read the distance in meters. Luckily a guy had a conversion paper and he would post the distance in ft and inches so all the people watching would be able to understand how far the jump was. Must have been one of those foreign lasers.
Trump will put an end to this. Only American lasers in 2017! -
Adding to the sorcery... I don't know if the public can access this, but on the Commentator Information System, if you click on TJ and click on "VMD Details", it instantly tells you distances between each phase of the jump, and I think if they fouled it is telling you how far they fouled by.
Instantly. Mind blown. -

Solved, the robots do not decide, an official uses the display provided to identify the spot.
In this case humans are not redundant.
The way it works, in simple terms, is by stereophonic cameras being placed so that they can capture the landing area, and which are calibrated before the event starts. For each attempt images are created and used to identify the exact landing point in the sand.
“It works the same as photo-finish in that a cursor is used to mark the landing point and then the software calculates the measurement,†says Boobyer. “The technology is too complicated for the officials to use themselves but they (the officials) make the final decision as to where the cursor should be placed on the image to measure the jump. We don’t make any decisions. The official does that,†she emphasises.
She argues Seiko can accurately record distances within 2mm: a system is more precise than the previously used EDM (Electronic Distance Measurement) system in which a spike or object was placed into the landing area which could lead to displacement of the sand.

I agree. I was watching the women's LJ and was convinced that DeLoach went into the lead with her (alleged 6.89m!? jump). It was clearly over 7m, when comparing it to the other jumpers around that mark. It looked about 7.10m to me, and it would certainly have won her a medal.
I couldn't believe it when it came up as being less than 7m! I didn't know at the time that robots were measuring it, until I browsed this thread. -

One of the greatest moments in the history of track and field was when Beamon bypassed 28 feet and went straight to 29 and watching the officials in Mexico City as they measured the jump. And then the excitement and tension until the measurement came up. Alas. Now gone.

As I remember Beamon heard the measure in meters and until someone quickly, and roughly, told him the distance he had no clue.
I heard it recounted that who ever it was said "That is beyond 28 feet" -

Back in the glory days. Like the Renaissance, a golden era we may never see again. Society has changed, where everyone wins excellence is lost. -
This isn't new--in use since 2010 by Seiko. Used in Eugene in 2014 for the World Jrs.
