 8-band WorldView2 satellite data can accurately identify 10 tree species in a temperate forest with an overall accuracy of around 82% and the object-based approach outperforms the pixel-based approach. The new WorldView2 bands have limited impact on classification accuracy if only four main tree species are separated, but using full spectral resolution significantly increases accuracy when more tree species are included. RF output can be used to evaluate the importance of spectral bands and reference dead equality, and a literature review on tree species classification is presented.
