Figure 13

Abundance maps estimated by SUnSAL, CLSUnSAL, SUnSAL-TV, SOMP, SMP, RSFoBa, and BSOMP and the distribution maps produced by Tricorder 3.3 software for the AVIRIS Cuprite scene. From top row to bottom row are the maps produced or estimated by Tricorder software, SUnSAL, CLSUnSAL, SUnSAL-TV, SOMP, SMP, RSFoBa, and BSOMP, respectively. From left column to right column are the maps corresponding to Alunite, Buddingtonite, and Chalcedony, respectively.
