Measuring a world record attempt for highest altitude catch

澳大利亚的测量和工程公司土地调查has been involved in a wide range of projects over their 24 years in business, completing gyroscopic mining surveys, laser scans of hospitals, engineering surveys of solar farms, sand accretion monitoring on Penguin Island and many more. Offering specialities in aerial, engineering and hydrographic surveys, laser scanning, spatial data analysis and other services, it’s fair to say there isn’t much in the surveying world they haven’t seen or worked on.

然而，当他们被要求为澳大利亚足球英雄布雷丹·菲沃拉（Bredan Fevola）的世界纪录试图从直升机上落下的美式足球赛中提供正式衡量标准时，他们正处于新领土上。但是，随着他们丰富的经验和莉卡·地理系统（Leica Geosystems）的高精度工具和现场软件的结合，他们准备应对挑战。

2021年6月，布伦丹·菲沃拉（Brendan Fevola）向听众宣布了他的共同主持的早晨广播节目Fox FM墨尔本的演出“ Fifi，FEV和Nick，”他将试图驱逐统治的吉尼斯世界纪录持有者，以获取美洲足球的最高海拔高度接球。打破纪录意味着Fevola需要抓住 - 或者，按照澳大利亚的规则足球，“马克”是从198米的悬停直升机中扔出的足球。击败的纪录是由国家橄榄球联盟（NFL）球员和超级碗冠军Rob Gronkowski创造的，仅几个月前就有188.9米的接球。

Fevola是前球迷最喜欢的AFL播放器转身主持人，他熟悉了巨大的成就：在他的职业生涯中，他是Coleman奖牌的两次获得赛季的冠军，这是一个赛季的大多数进球和一个全澳大利亚人在卡尔顿足球俱乐部任职期间的选拔。就像他在球场上的岁月一样，他提议的破纪录的冒险也是团队的努力。成功设置该活动包括协调直升机服务，与民航安全局的通关以及准确，可证明的测量。

This is where Land Surveys was called in to fulfil a crucial role on the team. Founded in 1997 by Peter Rullo in Perth, Western Australia, today Land Surveys has over 260 employees across the country, giving them the workforce and knowledge to master small and large projects alike. The Melbourne branch of Land Surveys was excited to bring their experience to contribute to what the morning radio show dubbed “Fev’s Massive Mark.”

“这是一个独特的机会，因为我们的墨尔本团队的通常环境涉及在高层和其他建筑工地上进行地面的调查工作。参与打破世界纪录的尝试真是太好了。”墨尔本土地调查团队说。

Tackling the challenge with a total station

As exciting as the opportunity was, Land Surveys had several challenges to contend with to meet the requirements by the Guinness World Record organization. To verify the height that the football would be dropped from the helicopter, Land Surveys used twoLeica TS16机器人总站在地面亚博5分钟快三上，而测量师则持有Leica GRZ4 360° prismthrough the open door of a helicopter.

TS16以完成各种测量任务和应用的能力而闻名，还具有功能等功能Autoheight, which measures instrument height with the push of a button. This enables a quick, error-free setup that lets the Land Surveys team get right to work. Additionally, the GRZ4 360° prism delivers an overall accuracy of 2-5 millimetres and an automatic target recognition of up to 600 metres, ensuring that the Land Surveys team would be able to lock onto their high-flying target to secure the measurement.

Paired withLeica Captivatefield software to capture the data necessary to supply evidence within Guinness World Record guidelines, their work “ensured that the ball was dropped from a precisely measured point high above ground level,” recalls the Melbourne Land Surveys team. “Our goal was to provide Brendan Fevola and his team with an accurate height measurement conducted by a qualified surveyor to verify that the NFL ball was dropped from the correct height.”

官方尝试：测量飞行目标的标记

当世界纪录打破尝试的一天到来时，Fevola和Team遇到了阴天的天空和间歇性的风阵风。在一个泥泞，宽阔的露天中间，他们完成了热身的巡回赛，并进行了调整以在重要的时刻设置。

从直升机上的目标很难，风使球的下降方向不确定。随着跑步跑步的几个接球，该团队为最终的正式尝试做了准备。与直升机中的机组人员进行交流，并锁定在棱镜上，给土地调查团队带来了独特的挑战。但是，最终，他们能够实现稳定的锁，确认了标记的正确高度。

With measurement validation, the football was thrown to Fevola, who appeared little more than a white dot below. Tracking the ball through the air as it plummeted 198 meters, Fevola raced across the field to intercept it. Unfortunately, the football narrowly ricocheted out of his hands.

尽管目前的唱片仍然不完整，但激动人心的尝试引起了国际关注，并为墨尔本“ Fifi，FEV和Nick”的球迷提供了一场有趣的活动。此外，土地调查创造了自己的记录，成功完成了一个稀有项目，辜负了他们的公司座右铭“没有问题，只是解决方案”，并证明Leica Geosystems设备是适合最具挑战性或最不寻常的测量的正确选择。任务。

That’s why, as the Land Survey’s team says, “Leica Geosystems is our company’s equipment of choice” and has been for 21 years.
