Satellite images are powerful tools for discovery and analysis, plus provide vivid illustrations. There is real potential for investigative journalists to make greater use of these space images, although they have used them to report on conflicts, climate change, refugees, forest fires, illegal mining, oil spills, deforestation, slavery and many other topics. Imagery, as one expert put it, “is independent of the official line of thinking.”

Among other benefits, images are great for showing change over time, such as retreating shorelines, growing islands or lost vegetation. Examining images can complement other research, possibly providing corroborating evidence.
