Description: Mountain Top Removal (MTR) is an ongoing coal mining operation. The study area for this map is located in the Appalachian Coal Region of West Virginia region of the Appalachian Mountains. Data provided by SkyTruth was analyzed to determine the difference in acreage of the MTR regions in 2010 vs 2005. "SkyTruth is a non-profit organization that promotes environmental awareness and protection with remote sensing and digital mapping technology." This final layer was created using the individually analyzed layers by each of the four members of Group 2. Each member of the group analyzed a different image in our study area. Using ERDAS Imagine, the Landsat bands were combined to produce a single multi-band image which was classified into MTR and Non-MTR regions based on their spectral reflectance values. The image was then manually reclassified and recoded in ArcMap. Only MTR polygons of more than 40 acres are displayed. Other criteria for the polygons included only those that intersected with ridges to ensure they are on a mountain top, a distance of 50 meters from rivers and streets, and 400 meters from major rivers and highways. 30 random points were placed in the area and they were compared to a similar dataset from 2005 to verify accuracy.
My role in this project was Group Leader. I analyzed each group member’s layer and confirmed acreage, accuracy, and general layout of their polygons. Natalie also performed these steps and together we decided to include in our final product the layers from myself, Donna, and Kelly. Natalie’s layer contained very few, small polygons with very low accuracy and all of her polygons were covered by Kelly’s. My layer also had very few, small polygons but with high accuracy and less coverage by other layers. Our final MTR layer included 219,589.76 acres, which is an overall decrease of 128,888.44 acres when compared to the 2005 dataset. The final accuracy is 93%. Overall, Group 2 accomplished the required tasks and responsibilities by analyzing their individual images, verifying accuracy, meeting specified criteria and communicating information effectively.
