  • [This dataset is embargoed until March 31, 2024]. The data set contains multi-temporal aerial imagery for two river segments in the Philippines. Imagery covers: (i) the downstream segment of the Bislak River and (ii) the confluence of the Abuan, Bintacan and Pinacanauan de Ilagan Rivers (referred to as ‘Ilagan’ in this data resource). Repeat aerial surveys were completed in 2019 and 2020. The data coverage includes the river channels, floodplains and surrounding areas. Raw aerial images were processed to produce spatially corrected orthoimagery (see supporting documentation). The resulting orthoimagery has a 0.2 m spatial resolution, containing information on the red, green and blue (RGB) bands. The work was supported by the Natural Environment Research Council (NERC) and Department of Science and Technology - Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD) – Newton Fund grant NE/S003312.

  • Repeat electrical resistivity tomography (ERT) measurements were conducted over four sites to capture the changing resistivity of the soil throughout the agricultural growing season, with measurements taken in Spring, Summer, and Autumn to detect the change between the construction, production, and post-harvest stages of the crop. Initial measurements were undertaken in April/May, Summer measurements in June/July, and final measurements in September 2021. Full details about this dataset can be found at
