Summary

Multispectral remote sensing data acquired by the Landsat 8 Operational Land Imager (OLI) sensor were analyzed using a new, automated technique to generate a map of exposed mineral and vegetation groups in the western San Juan Mountains, Colorado and the Four Corners Region of the United States (Rockwell and others, 2021). Spectral index (e.g. band-ratio) results were combined into displayed mineral and vegetation groups using Boolean algebra. New analysis logic has been implemented to exploit the coastal aerosol band in Landsat 8 OLI data and identify concentrations of iron sulfate minerals. These results may indicate the presence of near-surface pyrite, which can be a potential non-point source of acid rock drainage. Map data, in [...]

Purpose

These data show the spatial distribution of mineral and vegetation groups modeled from Landsat 8 OLI remote sensing data covering the San Juan Mountains and Four Corners Region. Automated analysis methodologies are employed to rapidly and cost-effectively generate maps which support U.S. Geological Survey mineral resource and mineral-environmental assessments.
