The outputs are in the form of a numerical value indicating the depth that each cell has had for both deposition and erosion (in metres). The two maps have then been added together by a GIS software, through a “raster calculator” function, whereby a new raster has been produced with the total topographic change (in metres). Values between -0.01 and 0.01 have been filtered out to remove noise in the final map. The final output has been compared to the observed post-event topography for controlling consistency with observed values. Overall raster statistics have also been analysed to identify whether any spurious or outlier values of individual cells were observed.","metadataDate":"2026-06-29T17:26:22","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/5d17ff4b-fc98-47e5-9d61-956b17254681","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/5d17ff4b-fc98-47e5-9d61-956b17254681.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Panici","givenName":"D.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"d.panici@exeter.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-7394-7981","address":{"city":"Exeter","country":"UK"},"fullName":"Panici, D.","pointOfContact":"University of Exeter"}],"publicationDate":"2023-09-22T00:00:00.000Z","publishers":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/5d17ff4b-fc98-47e5-9d61-956b17254681"},{"code":"10.5285/5d17ff4b-fc98-47e5-9d61-956b17254681","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Panici","givenName":"D.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"author","email":"d.panici@exeter.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-7394-7981","address":{"city":"Exeter","country":"UK"},"fullName":"Panici, D."},{"familyName":"Panici","givenName":"D.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"d.panici@exeter.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-7394-7981","address":{"city":"Exeter","country":"UK"},"fullName":"Panici, D.","pointOfContact":"University of Exeter"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"rightsHolder","email":"d.panici@exeter.ac.uk"}],"rightsHolders":[{"organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"rightsHolder","email":"d.panici@exeter.ac.uk"}],"spatialReferenceSystems":[{"code":"EPSG:3124","title":"PRS92 / Philippines zone 4"}],"spatialRepresentationTypes":["grid"],"spatialResolutions":[{"distance":"2","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2018-09-07","end":"2018-09-17"}],"title":"Modelled topographic change of the River Liang catchment, Philippines following Typhoon Mangkhut, 2018","topicCategories":[{"value":"elevation","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/elevation"},{"value":"geoscientificInformation","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/geoscientificInformation"},{"value":"inlandWaters","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/inlandWaters"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/9","http://onto.nerc.ac.uk/CEHMD/topic/13"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/5d17ff4b-fc98-47e5-9d61-956b17254681","useConstraints":[{"value":"This resource is available under the terms of the Creative Commons license","code":"license","uri":"https://creativecommons.org/licenses/by/4.0/"}]}
