Drones and aerial mapping

From Professional aerial mapping

Collects aerial photography of 1-10sqkm in a single flight at down to 5cm precision.
The eBee has a flight time of up to 45 minutes allowing to cover areas of up to 10sqkm in a single flight. With its 16MP camera it can shoot aerial imagery at down to 3cm/pixel resolution. The images can then be used to create maps and elevation models with a precision of 5cm.

Russian satellite’s 121-megapixel image of Earth is most detailed yet

There’s been a long history of NASA-provided “Blue Marble” images of Earth, but now we’re getting a different perspective thanks to photos taken by the Elektro-L No.1 Russian weather satellite. Unlike NASA’s pictures, this satellite produces 121-megapixel images that capture the Earth in one shot instead of a collection of pictures from multiple flybys stitched together. The result is the highest-resolution single picture of Earth yet. The image certainly looks different than what we’re used to seeing, and that’s because the sensor aboard the weather satellite combines data from three visible and one infrared wavelengths of light, a method that turns vegetation into the rust color that dominates the shot.
