Since those first images in 1972, multiple Landsat satellites have been launched with the ability to take increasingly detailed pictures of our world.
Focused on providing satellite imagery for large-scaled natural disasters, the Open Data program will provide open and accurate high-resolution satellite imagery and crowdsourced GIS layers.
Similar to the semantic web, techniques have been created for GIS, where finding and applying geospatial data requires protocols and standards that allow the large variety of data to be more easily searched.
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.
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.
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.
