Extracting fossil fuels and other natural resources from the land and seas can have huge impacts on the natural landscape and human communities. At SkyTruth, we use remote sensing and other digital tools to illuminate, analyze, and monitor the impacts of oil and gas drilling, mining, and other extractive activities. Because satellites have global reach and can repeatedly capture images of any area, they can be used to monitor mines, industrial sites, logging operations, protected areas, and other resource-management areas–anywhere, anytime. With access to a global archive of satellite images now stretching over four decades, we can also use current and historical images to show changes in the landscape over time.
