Cutting-Edge Airborne Geospatial Sensors for Reliable Data Collection

A versatile hybrid sensor optimized for large-area data collection, combining a large-format photogrammetric camera (31,520 x 13,440 pixels RGBN) with high-performance LiDAR. Features 58.0° image FOV and programmable 10-60° LiDAR FOV. Enables acquisition of highly consistent foundational geospatial data with fewer flying lines, reducing carbon footprint. This specialized equipment is ideal for various field applications, including large-area orthophoto creation, forest monitoring, and comprehensive assessment of ground infrastructure.

The Leica CityMapper-2, our second sensor of this type, has been modified this time to allow in-flight data access. This allows our proprietary software, using artificial neural networks, to automatically detect images with registered clouds or their shadows, out of focus or acquired with incorrect coverage. The ability to change the RGB lens to a model with a shorter focal length allows both hybrid projects for urban and regional areas, where only point clouds and vertical images are acquired, to be implemented efficiently. Our new technology opens up a wide range of possibilities in the field of surveying and spatial analysis.

Leica CityMapper-2 is designed for airborne urban mapping and offers unprecedented data capture performance to meet the growing demand for 3D data. This hybrid airborne sensor is equipped with LiDAR scanner, nadir camera and oblique camera. During a flight, the scanner captures 2 million 3D points every second, and cameras take six photos 150 MP each (RGB and NIR nadir images, as well as four oblique images). All data is captured simultaneously, using one coordinate system, making the data highly coherent and qualitative.

We are the world’s first company to have purchased Riegl VQ 1560i-DW scanner. The all-purpose device records two independent point clouds, emitting laser beams of two various wavelengths: a near infrared beam and green beam. Not only is the scanner capable of capturing topographic data, but shallow bathymetric data as well. Such a solution appears to be particularly useful while performing measurements of wetlands and watercourses, obtaining vegetation and flora-related parameters, registering high-voltage power lines, as well as evaluating losses and damage resulting from the occurrence of natural disasters.

It is our primary large-format airborne camera for acquisition of aerial images. The CMOS technology, applied in the camera, allows for obtaining 25% higher efficiency in comparison with the previous generation of the same cameras. The dynamic range of the device is at the level of 78 dB, whereas its pixel across track is at the level of 25,728 x 14,592 pixels. The camera records images in four spectral ranges: red, green, blue and near infrared.

The two medium-format airborne cameras, characterised by the resolution of 100 MPix in RGB and CIR dynamic ranges, are utilised as a set in combination with VQ 1560i-DW scanner for synchronous capturing of aerial images and aerial laser scanning data. The use of the solution in question results in increasing the efficiency of our aerial platform.

Although Riegl LMS-Q680i is currently being gradually replaced by more recent sensors, it is still possible to utilise the device in an effective manner, e.g. for smaller urban areas or while carrying out low-altitude flights under clouds. The pulse repetition frequency of the laser pulse is at the level of 400 kHz, whereas its maximum scanning angle reaches the level of 60°. The embedded rotating polygon mirror ensures regular distribution of points while performing specific measurements.

The high-quality thermal camera which can be used for simultaneous operation with a scanner and medium-sized camera. Recording and analysis of infrared radiation allows for measuring the temperature of structures on the land surface. The thermal measuring range is between -40°C and 120°C, whereas thermal sensitivity is lower than 0.005°C. The camera captures images with geometric resolution of 640 x 480 pixels at the speed of 6 images per second.
