Snow grooming for world cups

这Idre Fjall resort瑞典中部最近举办了第四次由国际滑雪联合会FIS安排的滑雪十字架世界杯。滑雪十字架是一项快节奏的滑雪运动，迅速转弯和跳高跳跃，同时有一个以上的滑雪者在路线上赛车。这项运动以公共友好和有趣的观看而闻名。

建立滑雪横路

这iCON alpine snow management solution来自Leica Geosystems用于准备滑雪横路和测量跳跃的确切高度并转弯以确保安全公正的竞争。该课程的设计模型由安装在雪地美容器上的机器控制解决方案读取，并基于夏季进行的裸露地形测量。可以计算确切的积雪高度以构建课程。

“我们even used the iCON alpine solution to measure the heights of the saved snow piles, and we also used UAVs [Unmanned Aerial Vehicles] to calculate exactly how much saved snow we had and how much technical snow we needed to produce,”explains Jonas Pålsson, snow groomer operator at Idre Fjäll.

Pålsson has worked with the iCON alpine solution for several years now –Idre Fjall was the first ski resort in Scandinavia to adopt the 3D snow depth measurement and snow management solution from Leica Geosystems.

“我一直在常规斜率和步道上使用图标高山解决方案。我使用该解决方案来测量深度，并尽早计划是否需要分配更多的积雪。这不仅节省了宝贵的时间，还节省了成本，因为可以更准确地计算出雪的需求，”解释说Pålsson。

IDREFjäll从位于顶部的本地GNSS基站开始。至确保连续连接和精确测量for the machines, the resort now subscribes to theHXGN SmartNet，作为Leica Icon Alpine解决方案的一部分，世界上最大的参考站网络。

在IDREFJäll上实施环境友好的技术

滑雪交叉比赛的计划在比赛开始之前就开始了。每年，IdreFjäll在一个季节中节省了下雪2-3 millimetre double-layered felt carpet。

“今年我们总共节省了260,000 cubic metres of snow，”IdreFjäll的运营经理Lars Fagrell解释说。“我们saved the snow from last year’s ski cross course, and even though 2018 was a record warm summer, we still had snow to build the course with less use of technical snow.”

Idre Fjall is adopting different technological solutions, such as the iCON alpine solution, to stay environmentally-friendly a be a snow-sure destination.

“我们总共1,500,000立方米的技术雪every season,”says Fagrell.“If we cansave 10 to 20 per cent of snow从上一年开始，这对我们来说意味着很大的成本。Leica Icon Alpine解决方案有助于我们控制雪量，因此我们可以将精确的雪高降雪和节省的积雪。” </p>

Efficient snow management

Idre Fjall also hosted the Speed Ski World Cup this year and created the steepest prepared track ‘Chocken’, or ‘shock’, for this purpose. Speed滑雪者可以达到每小时超过200公里的速度– this requires a100％的构建和修饰坡度。至create the steepest groomed ski slope in Scandinavia, Idre Fjäll is using the iCON alpine solution.

举办大型比赛需要有效的雪管理帮助整个度假胜地扩展滑雪季节。IdreFjäll配备了Icon Alpine解决方案，准备打开越野滑雪道和早期的高山斜坡，冬季季节将持续到复活节后一周，夏季活动接管。
