Leica CityMapper-2

The world’s only hybrid oblique imaging and LiDAR airborne sensor for fast and efficient digitisation of cities. High-Performance Hybrid Urban Mapping Sensor

The Leica CityMapper-2 provides high quality oblique imaging and LiDAR from one flight, saving time and costs. It captures two nadir (RGB/NIR) and four oblique 150 MP images. Together with a new generation 2 MHz pulse rate LiDAR it breaks all barriers of urban mapping. The newly developed optical system is equipped with Leica Geosystem’s unique mechanical forward-motion-compensation (FMC), which allows to capture high-quality imagery even in difficult lighting conditions.

Description

The 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.

The Leica CityMapper-2 is specifically designed for airborne urban mapping and offers twice the data collection performance to addresses this 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 0.8 seconds offering highest resolution to visualise every corner of the city. Together with a new generation 2 MHz pulse rate LiDAR, this sensor breaks all conventional barriers of urban mapping.

The Leica HxMap high-performance post-processing workflow moves into a new generation together with CityMapper-2. Edge computing creates fully calibrated high quality image data for rapid QC and emergency response applications.
