使用GIS可持续维护和保护树木

TyssenKrupp Steel Europe AG and its predecessor companies have been active in their core location of Duisburg for more than 120 years. Together with its subsidiaries, the company supplies a wide range of steel processing sectors. The individual locations, therefore, set benchmarks in terms of environmental impact, but not just in Germany. The company is active in the sustainable preservation of the environment. In this context and due to statutory requirements, two years ago the task was formulated to complete the entire tree population of Duisburg in the company's GIS using a field comparison process and other valuable data for preservation and care.

我们的目标是达到和保持均匀and scenically presentable tree landscape in an area of 800 hectares (2,000 acres) at the company campus This project will also make it possible to document replacement plantings. A prescribed tree injury assessment and appropriate tree care is planned to be reviewed yearly. In addition, the devastating storms of 2014 made it evident that the security of the trees at the campus is vitally important. The data will be used as a tender basis for these measures and will include the an updated version of all the green spaces on the premises. Exact figures pertaining to paved areas and green areas will be made available to the appropriate departments for the determination of drainage charges and for awarding contracts for green care measures. All supports for large industrial pipe systems located on the factory premises including pipeline routes and appropriate support numbers are recorded for the company's GIS.

正确的设备节省了时间
To perform this task economically and to complete it in a reasonable period of time, it was decided to work with the graphic field book FX Collector made by Frox IT Factory before the start of the project. The hardware platform consists of a Panasonic Toughpad FZ-G1 attached with a Leica Zeno GG03 GNSS SmartAntenna and a Leica CS25 GNSS plus with helix antenna.

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对FX收集器，Leica CS25 GNSS Plus和Leica Zeno GG03 Smartantenna的组合完全满意，” Thyssenkrupp Steel Europe AG的Dipl.-Eng。KlaudiusDrass说，以及负责IN-IN-IN-IN-IN-IN-IN-IN-IN房屋GIS。“与常规现场比较方法相比，效率提高了约30％。”

High mobility and data storage in the cloud
使用图形野外书籍，尤其是在树木茂密的地区，这是有利的。这是允许对数据完整性进行连续的现场视觉检查的最有效方法。该系统的优点是高度的移动性以及可以在没有繁琐的现场草图，其他地图或其他设备的情况下操作系统的事实。

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.

“防风雨CS25 GNSS Plus对雨，风和污垢具有抵抗力。电脑和天线整天都很容易携带。” Drass说。“电池持续了一整天，由于充电期很短，在早晨被充满电。“固定”解决方案的实现非常“快速” - 几乎没有等待时间。”

将办公室工作减少到最低
由于记录的数据的标准化高质量，因此在现场进行了很大一部分计划准备，将办公室的后处理减少到最低限度。办公室工作人员能够快速，轻松地将数据导入客户的GIS。这进一步强调了整个过程的效率。

“ Leica CS25 GNSS Plus为FX收藏家提供了一个很好的平台。Leica Zeno GG03 Smartantenna通过蓝牙与这两个片剂相连。测量很快就很容易，并且在短时间内返回了固定位置。” Drass说。“使用GNSS和众多设计功能测量的辅助点快速处理阴影区域。”
