Here at SkyTruth, we are always looking for new ways to visualize the environmental impact of human activity, so we’ve been playing with LiDAR (Light Detection and Ranging) data and digital elevation models (DEMs). We thought it would be interesting, and potentially useful, to create a profile of the terrain of a mine before and […]
If you haven’t met the Frack Family yet, check out this video! SkyTruth Reports: Meet The Frack Family from SkyTruth on Vimeo. Yolandita presents the imaginary Frack Family and their dog Rocky of Beaver County, PA who help us to visualize the staggering quantity of chemicals that were used in a typical frack job (hydraulic […]
