Currently, active leakages in water distribution networks (WDN) are identified and found by ground sensing and monitoring techniques based on the measurement of pressure differences, acoustic sounding and ground penetrating radar. Detecting the leak is troublesome for difficult area to access.
This study demonstrated the use of UAV multispectral and thermal images to determine the location of water leak.
It suggests that the relationship of vegetation index by visible and infrared data should be improved to the thermal emissivity surrounding.
