- •
We detect changes of Populus euphratica tree crowns by means of two very high spatial resolution imageries.
- •
We examine changes at the tree crown level by means of OBIA approach.
- •
We evaluate accuracies for tree crown diameter measures with reference data of visual tree delineation and field-based tree crown measurements.
