DigitalGlobe’s satellite imagery of the Fort McMurray wildfire, which uses “short wave infrared imagery (SWIR) to ‘cut’ through the smoke and identify the active footprint and burning hotspots” and reveals where buildings have been damaged or destroyed by the fire, can be viewed at Gizmodo and on DigitalGlobe’s own blog.
The European Space Agency has released this false-colour composite image of Ireland based on 16 radar scans by the Sentinel-1A satellite in May 2015. The colours show change over the 12 days of coverage: “The blues across the entire image represent strong changes in bodies of water or agricultural activities such as ploughing. […] Vegetated fields and forests appear in green. The reds and oranges represent unchanging features such as bare soil or possibly rocks that border the forests, as is clear on the left side of the image, along the tips of the island.” [ESA]
