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.

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.

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.
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.

... an old bloke guessing where to put his stick.

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

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

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.
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.

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.

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.

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.

This isn't new--in use since 2010 by Seiko. Used in Eugene in 2014 for the World Jrs.
