Joe Morrison discusses how new businesses are developing tools that use satellite imagery and SAR to quantify climate-related disasters.

Super-resolution Imaging

by Mark Altaweel

Super-resolution is a technique derived from computer vision approaches that tries to increase the quality of an image by employing algorithms and upsampling to improve image sampling.

The image of India on the right is an example of misappropriation of satellite imagery. The image was created from the satellite imagery on the left which shows night lights in India taken in 2003. NOAA manipulated the image to be an RGB Composite of Nighttime Lights Change with red representing 2003 and green representing 1992. The image has since made the rounds periodically on social media purporting to be an image of India on Diwali night.

Deepfake Satellite Imagery

by Mark Altaweel

Deepfake satellite imagery is imagery that has been synthetically to alter or change the appearance of an image, often replacing one scene for another.

The world settlement footprint, created in a online application called Urban Thematic Exploration Platform (TEP) sponsored by the European Space Agency (ESA), is the first map that combines optical and radar satellites to create a human urban footprint map of the world.
