Route mapping at Emlichheim wind farm

Westnetz GmbH是德国最大的分销网络运营商，拥有5,000多名员工和A覆盖面积为51,000平方公里。该公司向大约750万人提供电力，天然气，水和地区供暖。这包括负责计划，建设，维护和操作182,000公里的电网和24,000公里的气体分配系统。

在德国和荷兰之间边界的艾米希姆风电场项目记录了21-km route of cablesserving existing and new wind turbines. The cables will supply existing turbines and be ready to serve new ones. The existing turbines are 95 metre high, whereas the new ones will reach an overall height of最多143 m。

Up to400 points needed to be surveyed each dayduring the one-year project. Topography, such as roads, hydrants, slopes and buildings, were added from the land registry at the start of the project. The extensive field work was carried with a one-person surveying unit – the Leica Zeno GG03 Smart Antenna.

Carrying out the work in the field

许多项目参与者和建筑公司同时在项目站点上工作。在高峰时段，最多有四家钻井公司在现场，彼此相邻操作四个钻机。因此，测量部分是在开放式沟渠上进行的，需要同时进行。为了降低成本并提高效率，需要在现场执行协调和管理任务。

由于灵活的Zeno Smart天线与FX Survey（第三方和Cadastral软件）配对，因此可以同时进行测量，监视和测量。可升级的GNSS智能天线专为多功能使用而设计，允许用户选择现场软件和设置以适合每个工作流程和预算以及嵌入式自定义应用程序。整个系统主要由量身定制的FROX-IT软件和Zeno组成，可以立即使用。

The surveying system served as a central data hub, bringing together distinct types of information from current planning to boundary identification and topographical details.

"Using the graphic field book made it possible to plan and coordinate building operations on-site and in real-time. The cost advantages of having information immediately available on-site are obvious. Combined with the high precision Leica GNSS Zeno Smart Antenna it was possible to control, adjust and rerecord the planning down to the last centimetre,"said Mr. Markus Focks, network documentation and rights at Westnetz GmbH. Plan preparation needed to be done alongside surveying and be completed without the need for post-production. All planning data out of the FX Survey was transferred to the field into the Zeno Smart Antenna controller without the need of reworking the data. Further processing of the surveying data by the back-office team was provided as a DXF output, hence, the entire survey was available as a CAD graphic.

High accuracy, everywhere

By using Zeno Smart Antenna at its highest surveying quality, there wasno need to use a tachymeter.A measuring tape was not required either. The system delivered reliable positional accuracy within at least 3 centimetres.

The latest Leica Zeno GG04 Smart Antenna has a compact and lightweight design with enhanced tracking performance and precise point positioning without a mobile data collection. The GG04 can be used on Apple, Android and Windows smartphones or tablets. The newest Smart Antenna has extensive software support to be used with most data collection apps and software, making geospatial data collection easier than ever before.
