从激光扫描仪到实时的办公室

为了安全可靠地将天然气移至最终消费者，荷兰拥有高质量的天然气运输网络。对于不受干扰的气体输送，网络始终处于良好状态非常重要。因此，欧洲传输系统运营商Gasunie在荷兰和德国北部提供天然和绿色天然气的运输，他向主要天然气运输网络和区域天然气运输网络进行日常管理和维护工作。

The network in the Netherlands includes:

• 12,500 kilometres of pipeline
• 3,000个阀门时间表
• 80测量和控制站
• 1,000 gas receiving stations
• 13 compressor stations.

During the execution of maintenance and replacements, the delivery of gas to end customers continues. It is, therefore, a challenge to cause as little inconvenience as possible. For this reason, Gasunie first makes a detailed design of the pipes. Based on the design, the new components are prefabricated, so that the installation work in the field takes as little time as possible.

Combining multiple Leica Geosystems solutions that make laser scanning data available directly from the field to the customer and subcontractors, Gasunie can now save time and money with their re-designed Leica HDS workflows. Before integrating Leica Geosystems solutions, the time to deliver the as-built situation took quite long – now, a precise as-built model is ready within 24 hours.

混合和匹配解决方案

为了加速和改善整体流程，使用3D激光扫描与Advin咨询和工程公司结合进行了飞行员。已经审查了工作过程，并通过使用Leica Jetstream软件来简化点云访问和超高速度渲染，在数据处理中采取了创新的步骤。

在设计，零件的预制和运输之后，将在现场组装新的安装。使用Leica Viva GS16 GNSS智能天线和带有Leica Captivate Software的CS35平板电脑链接的Leica Nova MS60多稳态检查此安装。在迷人的软件中，检查表面应用程序会探讨模型和构建情况之间是否存在偏差，并将确定新情况是否符合Gasunie的要求。

The entire installation is mapped either with the MultiStation or with a Leica ScanStation P40. This measurement is processed and checked in the field and uploaded directly to JetStream server via a mobile 4G connection on the CS35.

“The system Leica Geosystems has developed fits optimally to optimise our workflows. From the design to the final stage of a construction, this method of working reduces time and, therefore, saves money. In particular, the saved point cloud as asset information during the construction phase may become useful many years later. We are furthermore capable to scan brownfield assets and transform this to real 3D-asset information with new (future) functionality,” said Sijbrand Stratingh, senior pipeline engineer at Gasunie.

受益于行业 - 领先的Point Cloud Project Server

Jetstream Server的使用具有许多重要的优势。数据在云中集中可用，因此所涉及的工程师可以直接访问数据。由于点云可在线获得，因此Gasunie还可以通过Truview Global和/或Jetstream Viewer直接访问此数据。然后，该公司可以使用点云进行讨论，并在需要时做出更好的明智决定。

Jetstream中的Smart Point Cloud技术允许通过在线连接毫不延迟查看和使用数据，而不会缺少任何细节。点云只有一个版本，因此只能进行一个备份。不必要的副本属于过去。

The selected choice when it has to be right

Thanks to Leica Geosystems combined solutions, the 3D design generated with the point cloud can seamlessly be adapted to the as-built situation. Gasunie no longer has any need to create a completely new as-built drawing from scratch. An update of the 3D-model is sufficient.

“我们始终努力使用最先进的硬件和软件，这些软件和软件可以为我们的客户提供最佳解决方案。可靠的高端设备供应商Leica Geosystems的选择是明显的。当我们真正遇到问题时，Leica Geosystems立即提供解决方案。” Advin测量师Jeffrey Den Ridder说。“测量项目后，挖掘的坑立即用土壤补充。因此，必须尽可能高效地进行测量，并且当然没有时间因设备有缺陷或技术故障而引起的延误。”

在完成了这些首次测试之后，Gasunie通过3D激光扫描和通过Autodesk®AutoCAD®Plant3D在云中的Jetstream通过Jetstream即时在线共享数据的工作流程非常积极。
