The main mission of the recently launched Sentinel-3B is to provide quality ocean and land monitoring. As part of the Copernicus program, GIS data and imagery will be made freely available.

High Altitude Pseudo-Satellites

February 22, 2018By Mark AltaweelGIS Industry

High altitude pseudo-satellites (HAPS) are systems or platforms that usually float or operate for long periods, sometimes for months, at about 20 km above the Earth’s surface and can be potentially used to complement earth observation satellites.
