Updating SkyTruth’s mountaintop removal mining dataset

In Appalachia, it is not uncommon to see the effects that mountaintop removal mining have on the surrounding ecosystems.  As someone living in the great Mountain State of West Virginia, one of the projects that caught my interest when I started my internship at SkyTruth was their work mapping the extent of surface mines in […]

Visualizing Elevation Change: Mountaintop Removal Mining

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 […]

Coal Mining: SkyTruth Work Helps Link Mountaintop Removal and Water Pollution

It’s official: strip-mining for coal using the massively disruptive process known as “mountaintop removal” definitively pollutes streams and rivers. Duke University researchers just announced the results of a new study (published July 2012 in the Environmental Science and Technology Journal) that quantitatively links the amount of mining activity within West Virginia watersheds to levels of […]

Mountaintop Removal Mining, Part 2: Mountains at Risk

SkyTruth, in partnership with Appalachian Voices, documented the impact of mountaintop removal coal mining (MTR) over a 59-county area in Kentucky, West Virginia, Tennessee and Virginia by mapping the extent of mountaintop removal mining over a 30 year period using satellite imagery. The historical record shows a 250% increase in MTR occurring over the last […]
