LandsatFor over forty years, Landsat has quietly however persistently been taking pictures of the surface of the Earth, amassing a formidable collection of information about our planet. This month, NASA and the U.S. Geological Survey (USGS) introduced that the trouble would proceed to span the generations, by transferring forward with the event and deliberate launch of LandSat 9 in 2023.

Images: 1) NASA’s Operation IceBridge found this large crack across the Pine Island Glacier. It is deep and vast enough to nearly engulf the Statue of Liberty, being 820 toes (~250 meters) across at its widest point and about 200 toes (~61 meters) at its deepest (NASA’s Operation IceBridge). 2) NASA’s Michael Studinger aboard the IceBridge DC-8 plane that surveyed the glacier. The realm cracking off may become an iceberg the scale of all of New York City, about 310 sq. miles (800 sq. km) (NASA’s Operation IceBridge).

A lot of the geologic processes that shape our planet, such because the creeping movement of tectonic plates, are sometimes too sluggish to see on human timescales, however on occasion, geology produces a moment with in-your-face depth. Simple haze removing can be achieved with i.landsat.dehaze This addons applies a bandwise haze correction utilizing tasscap4 (haze) and linear regression.
