Abstract: In this paper, we mapped wetland vegetation with 3 m spatial resolution,126-band HyMap image data in California’s Sacramento-San Joaquin delta. Specific vegetation indices were constructed and a decision tree model was used to identify wetland vegetation based on spectral analysis and field investigation. The result showed that we could construct suitable specific vegetation indices, according to the spectral difference obvious at near infrared bands(0.75-1.3 μm), which could be effective in distinguishing wetland vegetation and allowing for species-level detection necessary to map invasive species.
