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.

The VQ-1560-II system is a complete integrated measurement platform enabling simultaneous acquisition of laser scanning point clouds and RGB photos. The scanner can measure from up to 5.6 km, which allows for effective mapping of vast areas. With a scanning speed of 2 x 1.33 million points per second, it is the most effective device of that type available on the market. All sensors with the GPS / IMU positioning system are mounted on SOMAG GSM 4000 stabilised bed.

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.

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.
