铺平实时更改建模的道路

Author:John Welter

我的工作需要频繁的旅行，而在旅途中，一件很明显的事情是我们生活在快速变化的时期。城市由于增长而发生变化，随着运输基础设施的发展，农田的发展，农村地区正在发展，农田适应不断增长的人口，我们的城市地区似乎在一夜之间繁殖以提供住房。

在六边bob体育报道形，我们喜欢这样的说法：“您无法管理，您无法衡量的是。”在这些变化的背景下，“度量”表示“地图”。

The challenge with such rapid change is that it breaks the way we map – we recognise that changes have occurred, start a lengthy process to secure a budget, tender, and acquire new data to capture the changes. The new maps are often too late to be useful to manage the change and simply confirm what we already know.

To keep up with our changing world, mapping also needs to change. To achieve this, the old model needs to evolve to programs that continuously capture and make updated map data easily available. These Content as a Service (CaaS) programmes collect data according to consistent specifications and continual refresh schedules, creating a standardised product, suitable for many applications. The users of these applications are collectively underwriting the collection cost and can, therefore, pay a significantly reduced price. Using the principle of a sharing economy giving everyone equal access to the same data, and as such, democratising high-quality aerial data, a previously highly exclusive commodity.

第二需要是更有效的机载传感技术，它可以在一次飞行中收集更多数据，以减少制作地图的时间和成本。但是，单独的传感器无法完成工作。随着收集到的原始数据量增加，需要并行提高处理速度，从而使处理后的数据迅速传递给最终客户。捕获和处理图像和LIDAR数据的混合传感器和工作流程将更频繁地绘制LargesCale项目的驱动程序。

At Hexagon, we have invested in making this a reality and will continue to do so. With our network of collection partners, theHXGN内容程序, our CaaS initiative, is now entering its seventh year of continuous collection. The program has captured 25 million kilometres squared of data in North America and Europe, which is easily available online via purchase or subscription models.

在2016, we launched the world’s first airborne sensor that simultaneously captures nadir and oblique images and LiDAR elevation data, the Leica CityMapper and HxMap workflow. In 2019, we announced a 40% productivity enhancement with theCityMapper-2，允许空降地图公司在每次飞行中收集更多数据。
