A benchmark dataset for canopy crown detection and delineation in co-registered airborne RGB, LiDAR and hyperspectral imagery from the National Ecological Observation Network

Composite hyperspectral image (left) and corresponding RGB image (right) for the MLBS site.
The composite image contains near infrared (940nm), red (650nm), and blue (430nm) channels. Trees that are difficult to segment in RGB imagery may be more separable in hyperspectral imagery due to the differing foliar chemical and structural properties of co-occurring trees.
