环境管理与GIS和增强现实

The Grevel dump, like other hills in the Ruhr region in Germany, has been transformed from a waste dump site into a restored body planted with vegetation. This slag heap, or area of refuse material from a mine or industrial site, is known locally as the "Greveler Alm." The transformed waste dump now provides a new habitat for animals and has become a popular destination for excursions and local recreation with a fantastic view of the surrounding area.

But as in any green area, pests need to be managed and controlled. There are giant hogweed sites on the slag heap which are being recorded. The spread and growth of the giant hogweed, considered to be a noxious weed, is to be prevented by intensive mowing. The control is carried out in an ecological way without the use of additional chemicals.

Previously, a surveyor would record the locations of the giant hogweed with a GNSS controller, add the recorded coordinates into site plans and send PDF files to an engineering company. Engineers and landscape conservationists had then to print out these plans and navigate to the giant hogweed sites on the slag heap, using a traditional map-based navigation system.

Making invisible assets visible on-site

For this and further GIS requests, Tiemann & Partner need a lightweight and affordable GIS data collector that could be coupled to a smartphone, while providing a reliable position coordinate and be compatible with the AR application.

Fitting all criteria, Tiemann & Partner selected the FLX100 Antenna. For its first task, a field worker easily paired the antenna withLeica Zeno Connect softwareusing an Android smartphone with FX Reality App. The combination of the FLX antenna with the AR app fromFroxoverlays data into the visible world and provides users with the assets they need to visualise on location in real time.

“The digitalisation of the workflow leads to a considerable cost and speed advantage. The acquisition, data preparation and provision are accelerated by at least 70%,”says Ingo Tiemann, surveying engineer and CEO at Tiemann & Partner.

With the ability to combine feature-rich GIS data with AR into a smartphone or tablet, surveyors and non-surveying staff at Tiemann & Partner can now visualise any asset or measurement, such as property boundaries, canals, underground lines, drilling points, soil estimates, street inventories and much more.

在行走时，可以在他们的指尖看到以前存在的东西，包括管道和管道等地下物体。除了在视觉上体验数据外，Tiemann＆合作伙伴测量师还可以以厘米精度维护或测量任何点，线或区域。使用天线和APP解决方案，机组人员可以控制，添加属性或在3D AR或2D地图中记录。

“不再需要模拟计划，并且所有参与过程的人都提供了更大的灵活性。此外，数据始终是最新的，并且有一个中央数据库，”explains Ingo Tiemann, surveying engineer and CEO at Tiemann & Partner. “对于非服务员或制图师来说，使用增强现实进行搜索和校准更容易，更快。”

Searching and maintaining giant hogweed sites with AR

To record and maintain the poisonous weed, Tiemann & Partner used this solution and recorded point and line objects in every location while storing GIS metadata, such as DOP values and accuracy. All collected data was made available to stakeholders via ArcGIS.

“With the Augmented Reality approach, analogue plans and workflows become unnecessary. The data is collected by the surveying office or EDG staff directly on site using the FX Reality App and the FLX100 GNSS antenna. The captured data is written directly with attributes and photos into the Feature Service on the ArcGIS platform,”宣布Tiemann＆Partner的测量工程师兼首席执行官。

由于矿渣堆上的大部分草地，割草时不再可见巨型猪藻的位置。通过使用FLX100智能天线，现场工作人员能够在无数类型的灌木丛和树木中直接在现场搜索和控制巨型霍格韦德站点，以及山顶上的石质碎石，草药和草坪。天线在大约四公里长的路径网络中提供的位置是准确的。使用组合的解决方案，即使在割草的情况下，用户也可以轻松找到巨型霍格韦德站点。

“GNSS surveying creates a highly accurate coordinate of each location, which has clear advantages over a coordinate mapped to within 20m. Especially in regular checks, it can be seen directly whether the mowing work is successful against growth,”explains Ingo Tiemann surveying engineer and CEO at Tiemann & Partner.

Getting ready in less than one hour

Tiemann & Partner relies on Leica Geosystems as its technology provider. Before getting the FLX100 antenna, they relied on the Zeno Series GG04 plus for GIS data collection. A one-hour briefing is all Tiemann & Partner required to start collecting high-accurate data with the FLX100 smart antenna and FX Reality App.

“ GNSS天线的连接是通过插头和播放来工作的，在AR界面中的校准和搜索非常直观。Using the FLX100 on a pole, in a breast pocket, as a handheld standing on the object or on the ground is ideal. The flexibility is therefore enormously high in its application,”says Ingo Tiemann surveying engineer and CEO at Tiemann & Partner.

使用GNSS和AR的控制和维护属性

适用于割草的杂草的东西也可以用于无形的结构，例如地下线，公用事业，边界线和计划的建筑物 - 数字双胞胎的所有重要组成部分。将技术（如GNSS和VR）合并为单个工作流程，使每个人都可以以更高效，更聪明的方式体验和与数据进行交互。在实际环境中捕获和显示信息可以立即实现更好的决策，节省时间和资源。

Although there are many reasons someone would call a surveyor, with the FLX 100 in combination with FX Reality from frox non-professionals can easily collect GIS data too.
