Recently, the American Airborne Snow Observatory (ASO) company received the first batch of VQ-1560 II-S airborne laser scanners produced by RIEGL, a leading North American laser company. This new lidar system has higher laser power and high pulse frequency. , Which will enable ASO to measure snow water equivalent in the Dashan Basin more effectively.
It is reported that ASO is the only international supplier that uses airborne lidar, imaging spectrometer remote sensing technology and physical modeling for accurate snow mapping and runoff prediction. It is headquartered in California, USA. It was created by accepting the technology of the Jet Propulsion Laboratory transferred from NASA, and aims to expand ASO's snow mapping and runoff prediction business to various mountainous areas in the world.
By combining RIEGL lidar, imaging spectrometer data, and physical modeling, ASO maps mountain snow depth, snow water equivalent, and snow albedo images and data, which can provide water management agencies, irrigation districts, and municipalities with reliable high precision Traffic forecast. In addition, with climate changes, severe droughts in the western United States, and increased water demand, these measurements and predictions are critical to improving modern resource recovery capabilities.
In the past, the quality of ASO's series of mountain basin mapping has been significantly improved with the blessing of RIEGL LMS-Q1560. And now, the more powerful RIEGLVQ-1560 II-S enables ASO to optimize the collection capacity at a higher flying altitude in rugged terrain and bad weather, and at the same time in the changing terrain and the sky with extremely high forest coverage. Maintain high spot density and stability of surface inspection.
In addition, the new VQ-1560 II-S still implements RIEGL's unique dual-channel waveform processing lidar scanning technology concept, but also increases the laser power used for ultra-wide area surveying and mapping projects, which will be used in the whole state. Play a key role in large-scale collection plans and urban surveying and mapping plans.
James Van Rens, Senior Vice President of RIEGL USA, said: "Water is one of the most important resources on the planet. ASO's snow water equivalent measurement project is very important for water-stressed areas, especially in the western United States, so RIEGL is proud to be able to Become an ASO partner."
RIEGL's technological advancements have allowed ASO to see the possibility of high-density information collection on high mountains. Therefore, Thomas Painter, CEO and founder of ASO, said excitedly: "We must be in severe weather conditions. Accurate mapping of mountainous areas covered by large areas of snow. Through VQ-1560 II-S, we have obtained higher detection efficiency in high-altitude areas, and can penetrate the forest canopy to reach the lower layer of snow. ."
