Utilization Of Lidar Intensity Data And Passive Visible Imagery For Geological Mapping Of Planetary Surfaces, Taylor M. Haid

Electronic Thesis and Dissertation Repository

While lidar has been historically used for generating digital terrain maps and as a navigation tool, recent research demonstrates that lidar has many potential scientific applications, including high resolution analysis of geological outcrops. Case studies were completed at the Tunnunik impact structure, Victoria Island, Arctic Canada, and the Nickel Rim South mine, Sudbury, Canada, to assess the fidelity of characterizing and differentiating mineralogical and lithological units remotely by integrating passive visible imagery with lidar intensity data. Unsupervised classification via k-means clustering was performed on the fused datasets, with results indicating that lithologies can indeed be successfully differentiated with minor a …
