Environmental management with GIS and Augmented Reality

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.

但是，就像在任何绿色区域一样，需要管理和控制害虫。矿渣堆上有巨型猪藻网站正在录制。强烈的割草将阻止巨型猪藻的扩散和生长，被认为是有害的杂草。控制以生态方式进行，而无需使用其他化学品。

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.

使无形资产可见

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.

符合所有标准，Tiemann＆合作伙伴选择了FLX100天线。对于首次任务，现场工作者很容易将天线与Leica Zeno Connect softwareusing an Android smartphone with FX Reality App. The combination of the FLX antenna with the AR app fromfrox将数据覆盖到可见的世界中，并为用户提供实时可视化位置的资产。

“工作流的数字化导致了相当大的成本和速度优势。收购，数据准备和规定至少加速了70％，”says Ingo Tiemann, surveying engineer and CEO at Tiemann & Partner.

结合功能丰富的GIS数据的能力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。

“Analogue plans are no longer required, and greater flexibility is provided by all those involved in the process. In addition, the data is always up to date and there is a central database,”explains Ingo Tiemann, surveying engineer and CEO at Tiemann & Partner. “Searching and calibrating with Augmented Reality is much easier and faster for non-surveyors or cartographers.”

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。

Due to the extensive meadows on the slag heap, the locations of the giant hogweed are no longer visible when mowed. By using the FLX100 smart antenna, a field worker was able to search and control the giant hogweed sites directly on-site amidst countless types of bushes and trees, together with the stone rubble, herbs and lawns on the summit. The location provided by the antenna throughout the approximately four-kilometre-long network of paths was accurate to centimetres. With the combined solution, the user could easily find the giant hogweed sites even when mowed.

“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.

在不到一小时的时间内准备就绪

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.

“The connection of the GNSS antenna works by plug and play and the calibration and searching in the AR interface is extremely intuitive.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,”Tiemann＆Partner的Ingo Tiemann测量工程师兼首席执行官说。

Control and maintenance attributes with GNSS and AR

What applies to mowed weed can also be harnessed for invisible structures such as underground lines, utilities, boundary lines and planned buildings – all important components of a digital twin. Merging technologies, like GNSS and VR, into single workflows, allow everyone to experience and interact with data in more efficient and smart ways. Capturing and displaying information in real environments instantly enables better decision making, saving time and resources.

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.
