SkyTruth - Prepare Week

This week's assignment involved a few tasks to help analyze an area to determine where Mountain Top Removal Mining might be taking place.   This data would be used by SkyTruth.org to empower environmental activism.

Some of the skills needed for this project included:
  • Combining Landsat bands to get a multi-band image
  • performing unsupervised classification using ERDAS Imagine
  • Classifying images of different spectral values
  • Manually reclassifying and recoding imagery in ArcMap
It is important to note that this is a multi-week project, so a lot of the "noise" that you see around rivers and roads in this first pass of the analysis will be eliminated in future steps by buffering them out.
