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 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 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 with no reduction in efficiency, unlike traditional camera systems that have to decrease shutter and aircraft speeds to control image blur.

Optical System
  • Two 150 MP nadir cameras (RGB & NIR)
  • Four oblique 45° RGB cameras
  • Backside illumination (BSI) CMOS chip
  • Mechanical forward-motion-compensation (FMC)
  • Customised low-distortion lenses
  • A choice of two focal lengths for standard and high-altitude operation
LiDAR Sensor
  • 2 MHz pulse repetition frequency
  • Gateless Multiple-Pulses-in-the-Air (MPiA)
  • 3 cm range accuracy
  • Oblique scan pattern
  • Even point distribution across data set
  • USGS LiDAR quality Level 0 data from up to 2 km altitude

CityMapper-2 is the best equipped airborne sensor in the market for highly-productive creation of 3D digital twins of cities, transforming the way the industry enables the digitisation of the world we live in and allowing you to create the most detailed geospatial base layers such as 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. As part of Leica RealCity, CityMapper-2 is designed to create digital twins of cities in the shortest time, with the lowest operating expense.

Outstanding Accuracy


The newly developed 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 two configurations for standard and high-altitude flights to meet customers’ needs and local 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 Throughput


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. The LiDAR data undergoes discrete return extraction from the full waveform data for fast processing results, both of which are stored to allow the end user the ultimate flexibility.
