保护我们存在的基石

瑞士有悠久传统的培养和提出rving the country’s biodiversity and understand it is the cornerstone of our existence on Earth. The Swiss agriculture policy supports biotopes, or biological communities, and has proactively set agreements to protect and manage biotopes such as raised bogs, fenlands and dry grasslands, and land owners who carry out these set agreements receive compensation. New agricultural policy, taking effect from 2014 to 2017, has made direct payments to land owners managing biotopes possible. In order to assess the possible landscape quality effects of these supported biotopes, the Canton of Glarus’s Department Construction and Environment commissioned ARNAL, Büro für Natur und Landschaft AG, to conduct a study covering all areas in need of protection in Canton Glarus.

Robert Meier, CEO at ARNAL and project manager of this study, spent two weeks in the summer of 2014 with his intern Elias in the Glarus Alps. During this time, they measured land areas and collected other relevant information concerning the biotopes, and also finalised agreements with the local land managers. A Leica CS25 GNSS tablet PC was brought along to digitally collect data from the surface areas that needed to submit assessments.

作为一家具有广泛环境经验的公司，与客户紧密合作，ARNAL始终支持Envirnoment，首先考虑了景观需求。2014年夏天，ARNAL被委托制定新的土地管理协议并更新现有的协议，以保护Glarus Alps中发现的脆弱生物型。为此，需要评估土地面积规模，并与当地的土地管理者协商协议。

检查和扩展生物台
During this project, intern Elias gained first-hand experience of what it meant to be an ecologist. While on their field hikes, Robert Meier explained to Elias the riches and diversity to be found in each of the biotopes and demonstrated to Elias how to use the Leica Zeno GIS tablet. In just a short period of time, Elias was familiar with the device and ready to start collecting data.

在罗伯特·梅尔（Robert Meier）的监督下，埃里亚斯（Elias）能够使用平板电脑的集成GPS和Leica Zeno Field应用程序来验证现有的生物管尺寸。需要更改的任何区域尺寸均使用精确的位置数据直接在现场进行。正如罗伯特·梅尔（Robert Meier）所解释的那样：“使用Leica Zeno领域，我们不仅能够记录和纠正几何表面，而且还可以输入有关管理相应区域的有价值的信息，以直接在现场进行评估。”

Back at the office, the data was imported directly into the QGIS GIS system, a free and open source program for creating, analysing and publishing geospatial information. Thanks to the work carried out with the Leica Zeno Field, it was no longer necessary to manually draw the areas in a field map and digitise them later in the office.

Ideal orientation in the field – even with poor weather conditions
众所周知，天气在山区可能会很快变化，2014年夏天也不例外。这使得在雾化不佳的情况下更有帮助。“我们曾经为此使用纸质地图，必须保护它免受雨水的保护。多亏了防水Leica CS25平板电脑，我们可以将雨伞留在后面，并通过定位来查明我们在该地区的确切位置。梅尔说：“也可以将导航功能“试播”到所需的位置。”

Making invisible boundary lines visible
The Leica CS25 tablet offered the team other advantages as well, such as the ability to display boundary lines, which often can't be seen or found. “Property boundary lines, for example, play a crucial role when it comes to direct payments. Using the Leica CS25, we were able to show land managers the boundary lines in the field. Land usage boundaries, such as the boundaries of forests, also play a role regarding payments. We could show these boundaries to them on the tablet as well, and made use of them as a basis for discussion,” explained Meier.

“Our experiences with the Leica CS25 GNSS in this project were very positive, as some work steps could be consolidated and others, such as sketching, weren't needed at all. The data was recorded quickly and precisely with the GPS, meaning that we could reduce the amount of time spent on location by a considerable degree,” concluded Robert Meier.

Believe it or not, this can have its downsides, too. Intern Elias would have gladly spent more time in the Glarus Alps: “I had a lot of fun out there. We were outside every day, and when the day was done, we knew that we had done something positive for the environment.”
