NERC EDS Environmental Information Data Centre 10.5285/e040ff39-2176-4ed4-9e5d-861bdae8a030 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.

Capture One, Adobe Lightroom and TerraPhoto software were used to process the raw images into orthoimagery. The main processing steps were: (1) colour corrections, (2) tie-point definition, (3) colour points and selection shapes, and (4) rectification. Orthoimagery is provided as .tif files. The positional accuracy of the orthoimagery was checked and verified by the third-party responsible for completing the aerial surveys.
