Leica CityMapper-2 High-Performance Urban Mapping Sensor

For fast and efficient digitisation of cities, this hybrid oblique imaging and LiDAR solution provides the highest productivity and unmatched data accuracy

这need for accurate aerial data in metropolitan areas goes beyond traditional data products because the fast-changing urban environments require more frequent and hence more efficient updates of geospatial base layers.

这Leica CityMapper-2 is specifically designed for airborne urban mapping and offers twice the data collection performance to addresses the urgent need for 3D data. The world’s only hybrid oblique imaging and LiDAR airborne sensors, captures two nadir (RGB/NIR) and four oblique 150 MP images every 0.9 seconds providing the highest resolution to visualise every corner of the city. With a new generation 2 MHz pulse rate LiDAR, this sensor breaks all conventional barriers of urban mapping.

这newly developed Leica MFC150 optical system is equipped with Leica Geosystem’s独特的机械前进动力补偿（FMC），即使在艰难的照明条件下，也可以捕获高质量的图像，而效率没有降低与传统的相机系统不同，这些系统必须提高快门速度并降低飞机速度以控制图像模糊。

CityMapper-2是市场上最好的机载解决方案，用于高度生产的3D数字双胞胎城市。传感器改变了我们如何数字化我们生活的世界，并允许您创建最详细的地理空间基层层，包括正射击，点云，3D建筑模型和网格，全部从一次飞行中。

性能助推器

该系统允许用户以更高的飞行高度和速度收集，同时仍提供相同的GSD和位置准确性，因此该系统为城市地图应用提供了无与伦比的效率。作为...的一部分莉卡实体, CityMapper-2 is designed to create digital twins of cities in the shortest time, with the lowest operating expense.

Outstanding Accuracy

这newly developed Leica MFC150 cameras with customised low-distortion lenses can deliver pixel sizes as small as 2 cm at high flying speeds thanks to mechanical forward-motion-compensation (FMC). The 2 MHz linear-mode LiDAR sensor delivers 3 cm range accuracy and is optimised for data collection in urban environments.

Operational Flexibility

系统有三种配置for low, standard and high-altitude flights to meet customers’ needs and to adapt to local weather and flight regulations. The CityMapper-2 is a compact package with embedded system controller and storage, which makes it easy to install in any survey aircraft.

最高数据吞吐量

这Leica HxMaphigh-performance workflow was upgraded to meet the demands of CityMapper-2 data processing. Edge computing creates fully calibrated high quality image data for rapid QC and emergency response applications. On the LiDAR side, discrete returns are extracted from the full waveform for the fastest processing speeds.
