Characterising Termite Mounds in a Tropical Savanna with UAV Laser Scanning

Barbara D'hont, Kim Calders, Harm Bartholomeus, Tim Whiteside, Renee Bartolo, Shaun Levick, Sruthi M. Krishna Moorthy, Louise Terryn, Hans Verbeeck
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.  ...
