Tree crown mapping in managed woodlands (parklands) of semi-arid West Africa using WorldView-2 imagery and geographic object based image analysis.

The correlation coefficients ( r s ) presented in Table 8 and Figure 6 are all highly significant (<0.05) and show that the delineation accuracy is a function of tree crown size with lowest r s for small trees (0.419) and highest r s for large trees (0.905).
