Mapping invasive species and spectral mixture relationships with neotropical woody formations in southeastern Brazil
Two invasive species were spectrally detected in a neotropical environment via multiple endmember spectral mixture analysis. Spectral subsets, continuum removal and methods for selecting endmembers were assessed. Near-infrared and shortwave infrared hyperspectral datasets were critical for identifying the invasive species. These species tend to be overestimated in the woodland savanna. The 1-m pixel-based endmember fractions were preserved at the crown scale.
