Satellites flying overhead in Earth’s orbit largely present a two-dimensional view of our planet, however a Florida-based firm is hoping to alter that through the use of satellites to routinely construct 3D maps of Earth’s complete floor.
Throughout the Geospatial World Discussion board, held from Might 2 to 5 in Rotterdam, the Netherlands, NUVIEW introduced its plans to launch a constellation of satellites, which is able to use LiDAR to map Earth in three dimensions.
“Our LiDAR satellite tv for pc constellation will supply a wealth of data that has by no means earlier than been accessible at scale, driving innovation and progress all through quite a few industries and revolutionizing the way in which we perceive and work together with our planet,” Clint Graumann, CEO and co-founder of NUVIEW, mentioned in an emailed assertion.
It’s not clear when NUVIEW plans on launching its LiDAR constellation, however the firm claims it already has $1.2 billion in contracts with potential prospects for its knowledge.
LiDAR, which stands for Mild Detection and Ranging, makes use of pulsed lasers to measure distance by detecting the time it takes for mirrored mild to return to the receiver. The know-how is ready to map Earth’s typography in nice element, and it does so by sending down a gradual stream of laser pulses that make their manner by way of bushes and different forms of vegetation. To date, most different makes an attempt to make use of LiDAR when mapping the Earth’s floor use drones or planes. NASA’s ICESat-2, which launched in 2018 to measure ice-sheet elevation within the Arctic, is considered one of a small variety of satellites that use LiDAR from orbit.
In consequence, solely about 5 % of Earth’s landmass has been mapped with LiDAR, in line with NUVIEW. However because of latest technological improvements, in addition to the evolving area business that enables for higher, cheaper entry to orbit, NUVIEW was in a position to design a constellation of 20 LiDAR satellites. Fashionable satellites are additionally extra able to dealing with the excessive energy calls for of the LiDAR sensors.
NUVIEW claims that its LiDAR constellation “will accumulate knowledge greater than 100 occasions sooner than present industrial aerial options.” The corporate predicts there might be a big marketplace for its knowledge, which can be utilized by farmers to optimize crop yields and water utilization, in addition to city planners to create extra environment friendly and sustainable environments for cities, in line with NUVIEW.
