\(O_{tree}^{health}\) calculated as \(f_{health}(\Delta _{GCVI}) \otimes O^{tree}\). It is a three-value mask where each pixel is either 0: no-tree (not visualized), or 1: healthy tree (green), 2: unhealthy tree (yellow). The image shows additionally the buildings (brown), critical buildings locations (blue cylinders) and considered roads (black lines). The satellite images is acquired from PlanetScope16. The image has been created with QGIS 3.2017.
