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.
- 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
- 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.
Major efficiency improvement to airborne urban mapping
(19 September 2019) The next generation hybrid oblique imaging and LiDAR sensor provides fast and efficient digitisation of cities. As part of the Leica RealCity solution, which combines the CityMapper-2 with the Leica HxMap high-performance processing workflow, the new sensor is designed to provide faster updates while preserving image quality over a wide range of flying conditions.
Bluesky uses Leica CityMapper to capture major UK cities in 3D
(21 November 2018) Using the CityMapper, Bluesky was able to capture parts of London, Manchester and Birmingham as well as Brighton, Bristol, Cambridge, Norwich, Nottingham and Oxford. Bluesky intends to increase its coverage by capturing additional towns and cities across the UK and Ireland in 2019. It is the first time this technology has been used commercially in the UK to this level.
A new era of airborne city mapping
(15 December 2017) Using a professional workflow solution as part of airborne mapping applications is as important as high-end sensor technology. Urban environments are subject to rapid changes and thus have a higher need for up-to-date data. Airborne mapping companies APEI, France, and Fugro, USA, were amongst the first to adapt the CityMapper.
