Landsat 9 Will Launch in 2020

The Landsat series of satellites has been imaging the Earth’s surface for nearly 50 years, providing vital imagery for a range of purposes from the natural sciences to civil administration and conflict monitoring. NASA and the USGS recently announced that the next iteration of the program, Landsat 9, is due to launch in 2020.

Structure-from-Motion (SfM). Instead of a single stereo pair, the SfM technique requires multiple, overlapping photographs as input to feature extraction and 3-D reconstruction algorithms.

Making 3D Models with Photogrammetry

With the prevalence of smartphones and drones, photogrammetry is now widely present as an effective and cost-efficient method to easily recreate 3D models of large areas and specific objects or buildings.

Mini Satellite Constellation to Explore the Outer Reaches of Our Atmosphere

An international scientific project is conducting an unprecedented study of the atmosphere’s outermost layer. Fifty tiny satellites will measure the attributes of the thermosphere, a poorly understood but vitally important region.
