Leak Detection in Water Transmission Systems by Multispectral Remote Sensing With Airplane and UAV

Water leak detection in water transportation mains outside urban areas by airborne remote sensing has been assessed with a series of measurement campaigns in 2017 over SCP (Société du Canal de Provence - France) network in Provence (Fr). The most appropriate wavelengths and combination for revealing high moisture areas and artificial leaks coming from this image database (VNIR, SWIR, TIR spectral range) allowed us to select the best onboard instrumentation for both types of platforms (manned & unmanned). This work aims at validating the choice of this instrumentation associated with the multispectral approach (Triangle method) in the framework of a new airborne campaign in October 2018 with a plane and an UAV in operational environment.
