为实时更改建模铺平道路

作者：约翰·韦尔特

My job requires frequent travel, and one thing that becomes very obvious during my trips is that we are living in a time of rapid change. Cities are changing due to growth, rural areas are developing as transportation infrastructure evolves, farmlands adapt to feed a growing population, and our urban areas seem to multiply overnight to provide housing.

在六边亚搏苹果app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。同时捕获和处理图像和LIDAR数据的混合传感器和工作流将更频繁地绘制LargesCale项目的驱动程序。

在六边亚搏苹果app形，我们已经投资了实现这一目标，并将继续这样做。与我们的收集合作伙伴网络，HxGN Content Program, 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.

In 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。
