Paving the Road to Real-time Change Modelling

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。

At Hexagon, we are fond of the saying: “You can’t manage, what you don’t measure.” In the context of these changes “measure” means “map.”

如此快速的变化面临的挑战是，它破坏了我们的映射方式 - 我们认识到发生了变化，开始一个冗长的过程，以确保预算，招标和获取新数据以捕获更改。新地图通常太晚了，无法管理更改并简单地确认我们已经知道的内容。

跟上变化的世界,也映射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.

The second necessity is more efficient airborne sensing technology which enables the collection of more data in a single flight to reduce the time and cost of making maps. However, the sensor alone does not get the job done. With growing amounts of collected raw data, processing speeds need to be increased in parallel, allowing for the swift delivery of the processed data to the end customer. Hybrid sensors and workflows that capture and process imagery and LiDAR data simultaneously will be the driver to map largescale projects, more frequently.

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，我们的CAAS倡议现在正在进入其连续收藏的第七年。该计划在北美和欧洲捕获了2500万公里的数据，可以通过购买或订阅模型在线获取。

2016年，我们启动了世界上第一个空降传感器，该传感器同时捕获了Nadir和Oblique Images以及LiDar Heivation Data，Leica CityMapper和HXMAP工作流程。2019年，我们宣布了40％的生产率提高CityMapper-2, allowing airborne mapping companies to collecting more data during every flight.
