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.\n\nThe 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.\n","distributionFormats":[{"name":"TIFF","type":"image/tiff","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/S003312","orcid":false,"ror":true},{"funderName":"Department of Science and Technology - Philippine Council for Industry, Energy and Emerging Technology Research and Development","funderIdentifier":"https://ror.org/05tgxx705","awardNumber":"NE/S003312","orcid":false,"ror":true}],"id":"e040ff39-2176-4ed4-9e5d-861bdae8a030","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/e040ff39-2176-4ed4-9e5d-861bdae8a030.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"keywordsOther":[{"value":"river","uri":"http://www.eionet.europa.eu/gemet/concept/7244"},{"value":"geomorphology","uri":"http://www.eionet.europa.eu/gemet/concept/3654"},{"value":"aerial photography","uri":"http://www.eionet.europa.eu/gemet/concept/14165"},{"value":"river management","uri":"http://www.eionet.europa.eu/gemet/concept/12189"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Aerial surveys were completed on the following dates:\nBislak 2019 – 21 March 2019\nBislak 2020 – 22 January 2020\nIlagan 2019 – 5 April 2019\nIlagan 2020 – 14 February 2020\n\nRaw images were acquired as .tif files.
