Characterising Termite Mounds in a Tropical Savanna with UAV Laser Scanning
2021
Remote Sensing
We detected 81% and 72% of the termite mounds in the high resolution (1800 points m−2) and low resolution (680 points m−2) UAV-LS data, respectively, resulting in an average detection of eight mounds per ...
Flight 1 eventually covered an area of 98,000 m 2 with an average point density of 1800 pts/m 2 , while Flight 2 covered 340,000 m 2 and resulted in a point density of 680 pts/m 2 . ...
Macrotermes mounds are large features (up to 10 m wide and 3 m) and therefore more readily detectable. ...
