  • Drones Map the Environment with 1000 Times the Detail of Satellites

    By Alton Parrish (Reporter)

    Drones are the future for nature mapping and monitoring. – Compared to satellite pictures, drone images provide 1,000 times better image resolution and one million times more data points, says Kasper Hancke, a marine biologist at Norwegian Institute for Water Research (NIVA).

    It is a surprisingly nice and calm summer day at Søre Sunnmøre, by the outermost islands of Western Norway. While off-piste hippies are still skiing on the very last summer snow further in the fjords, the kayak season has already started out here, in a silent bay close to Fosnavåg. But it is not all peaceful. A buzzing noise is heard from above; a massive drone is flying systematically along the shoreline. By the shore, a man is standing with seaweeds to his knees, holding in his arms a rack taller than himself.

    With a drone for the first time

    The man is marine biologist Kasper Hancke from the Norwegian Institute for Water Research (NIVA). He is here to photograph a section of nature that most of us usually don’t see – the zone between the low and high tide.

    – Usually, when we are mapping the tidal zone, we do the registration manually: Spiral wrack, bladder wrack, knotted wrack, toothed wrack, and so on. But now we try, for the first time, to take pictures from above instead, says Hancke.

    – When the drone flies 100 meters above the ground, it takes pictures with a 3 x 3 cm resolution. This offers 1,000 times better image resolution, or one million times more data
    points, than satellite images, which often have a 30 x 30 m resolution.

    Hancke is convinced that drones are the future for mapping and monitoring of nature and natural resources.

    When the drone flies 100 meters above the ground, it takes pictures with a 3 x 3 cm resolution. This is 1,000 times better than a satellite, which takes pictures with a 30 x 30 m resolution.
