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.

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.

以前，测量师将使用GNSS控制器记录巨型霍格韦德的位置，将记录的坐标添加到现场计划中，并将PDF文件发送到工程公司。然后，工程师和景观保护主义者必须使用传统的基于地图的导航系统来打印这些计划，并导航到矿渣堆上的巨型霍格远地。

Making invisible assets visible on-site

为此，Tiemann＆合作伙伴需要一个轻巧且负担得起的GIS数据收集器，该收集器可以耦合到智能手机，同时提供可靠的位置坐标并与AR应用程序兼容。

Fitting all criteria, Tiemann & Partner selected the FLX100 Antenna. For its first task, a field worker easily paired the antenna withLeica Zeno Connect software使用带有FX Reality应用程序的Android智能手机。FLX天线与来自AR应用程序的组合froxoverlays 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%,”Tiemann兼合作伙伴的测量工程师兼首席执行官Ingo Tiemann说。

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.

What previously existed on paper can be seen at their fingertips as they walk, including underground objects like pipes and ducts. Besides experiencing data visually, Tiemann & Partner surveyors can maintain or measure with centimetre accuracy any points, lines or areas. With the antenna and app solution, crew members can control, add attributes or record in 3D AR or in a 2D map.

“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,”Tiemann＆Partner的测量工程师兼首席执行官Ingo Tiemann解释说。“Searching and calibrating with Augmented Reality is much easier and faster for non-surveyors or cartographers.”

Searching and maintaining giant hogweed sites with AR

为了记录和维护有毒的杂草，Tiemann＆Partner在存储GIS元数据的同时，在每个位置使用了该解决方案，并记录了点和线对象，例如DOP值和准确性。所有收集的数据均通过ArcGI提供给利益相关者。

“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,”declares surveying engineer and CEO at Tiemann & Partner.

由于广泛的草地在渣堆上,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测量创建了每个位置的高度准确坐标，该坐标比映射到20m以内的坐标具有明显的优势。尤其是在定期检查中，可以直接看到割草工作是否成功地抵抗了增长，”Tiemann＆Partner的Ingo Tiemann测量工程师兼首席执行官解释说。

Getting ready in less than one hour

Tiemann＆合作伙伴依靠Leica Geosystems作为其技术提供商。在获取FLX100天线之前，他们依靠Zeno系列GG04 Plus进行GIS数据收集。一个小时的简报是所有Tiemann＆合作伙伴开始使用FLX100智能天线和FX Reality应用程序收集高精确数据。

“The connection of the GNSS antenna works by plug and play and the calibration and searching in the AR interface is extremely intuitive.在物体上或地面上的手持式手持式掌握时，将FLX100在杆子上，胸口袋中，是理想的。因此，灵活性在其应用中非常高，”says Ingo Tiemann surveying engineer and CEO at Tiemann & Partner.

Control and maintenance attributes with GNSS and AR

What applies to mowed weed can also be harnessed fo

r 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.

尽管有人会称呼测量师的原因有很多，但FRX 100与FROX非专业人士结合使用FX Reality的原因也很容易收集GIS数据。
