Sustainably maintain and protect trees using GIS

Tyssenkrupp Steel Europe AG及其前身公司在杜伊斯堡的核心位置处于活跃于120多年。公司与其子公司一起提供了广泛的钢铁加工领域。因此，各个地方在环境影响方面设定基准，但不仅仅在德国。该公司积极在可持续保存环境中。在这方面，由于法定要求，两年前，任务被制定为使用现场比较流程和其他有价值的保存和关怀的有价值数据来完成公司GIS的整个树群。

目标是在公司校园内的800公顷（2,000英亩）面积上实现和维护一个同质和漂亮的展示树景观，该项目也可以将替代种植造成替代品。计划每年审查规定的树伤害评估和适当的树护理。此外，2014年的毁灭性风暴使其显而易见的是，校园里的树木的安全性很重要。数据将被用作这些措施的招标基础，并将包括房屋内所有绿色空间的更新版本。将提供与铺设区域和绿色地区有关的确切数据，以确定排水费，以确定排水费用，并授予绿色护理措施合同。所有位于工厂房屋的大型工业管道系统的支持都记录了公司的GIS。

The right equipment saves time
为了经济上经济地进行这项任务并在合理的时间内完成它，决定使用FROX IT工厂在项目开始前的图形现场书籍FX收集器。硬件平台由一个与Leica Zeno GG03 GNSS Smartantenna和Leica CS25 GNSS加上的Panasonic Guldpad FZ-G1组成，带有Helix天线。

The objects to be recorded were identified with the highly accurate Leica Zeno GNSS SmartAntenna and composed using the numerous FX Collector available drawing functions. In addition, mixed methods were used; the rapid interaction of the FX Collector was used in combination with the Leica Zeno GNSS SmartAntenna. This method quickly provides position data auxiliary points, which are then used to construct hard-to-reach objects on the tablet.

All background data (aerial photographs, Web Map Service, CAD data) were stored in geo-referenced format in the FX collector. Examining surfaces and existing trees, measurement of the pipe supports as well as the orientation of the location were thus greatly simplified. It was thus possible to create the extensive dataset quickly and in high quality.

“ThyssenKrupp Steel Europe AG is totally satisfied with the combination of the FX Collector, Leica CS25 GNSS plus and Leica Zeno GG03 SmartAntenna,” said Klaudius Drass, Dipl.-Ing Geography at ThyssenKrupp Steel Europe AG, and the person responsible for the in-house GIS. “Efficiency was increased by about 30 percent compared to conventional field comparison method.”

云中的高移动性和数据存储
It was advantageous to work with the graphic field book, especially in the densely wooded areas. It’s the most efficient method for allowing continuous on-the-spot visual checks to be made regarding the completeness of the data. The advantage of the system is the high degree of mobility and the fact that the system can be operated without cumbersome field sketches, additional maps or additional equipment.

In particular, the Leica CS25 GNSS plus in combination with the helix antenna offers reliability, ease of use, mobility, and delivers sub-decimetre accuracy. The Panasonic Toughpad FZ-G1 with the Leica Zeno GG03 SmartAntenna on the pole was used in all other areas where higher accuracy was required.

The project was backed up on site to the cloud daily so preliminary results could be available immediately to office staff. FX Collector's Session feature was used in this context to allow the data to be exported on a daily basis without having to create a new project each day.

结果以数字形式提供。树一个nd pipe supports were exported using FX Collector's table-driven interfaces so that they could be read directly into ThyssenKrupp's GIS system. The changed green spaces as well as the new green spaces were replaced or supplemented in GIS.

“The weatherproof CS25 GNSS plus is resistant to rain, wind and dirt. The computer and the antenna were easy to carry throughout the day,” said Drass. “The batteries lasted all day and were fully charged by morning due to the short charging period. The ‘fixed’ solution was achieved extremely ‘quick’ – there was hardly any waiting time.”

Reduction of office work to a minimum
A large portion of the planning preparation was conducted in the field, reducing post-processing in the office to a minimum due to the standardised high quality of recorded data. The office staff was able to import the data quickly and easily into the client's GIS. This further emphasises the efficiency of the entire process.

“The Leica CS25 GNSS plus offers a good platform for the FX Collector. The Leica Zeno GG03 SmartAntenna was connected with the two tablets via Bluetooth. Measuring was done quickly and easily, and a fixed position was returned within a short period,” said Drass. “Shaded areas were processed quickly using measured auxiliary points via GNSS and the numerous design features.”
