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
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 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.
The newly developed Leica MFC150 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 with no reduction in efficiency, unlike traditional camera systems that have to increase the shutter speed and decrease the aircraft speed to control image blur.

The CityMapper-2 is the best equipped airborne solution in the market for highly-productive creation of 3D digital twins of cities. The sensor transforms how we digitise the world we live in and allows you to create the most detailed geospatial base layer including orthophotos, point clouds, 3D building models and meshes, all from one single flight.
Performance Booster
Allowing users to collect at higher flying heights and speeds while still delivering the same GSD and positional accuracy, this system provides unmatched efficiency for urban mapping applications. CityMapper-2 is designed to create digital twins of cities in the shortest time, with the lowest operating expense.Outstanding Accuracy
The 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
The system is available in three configurations 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.Highest Data Throughput
The Leica HxMap high-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.
