The resulting elevation model resolutions are approximately: Ortho-mosaics 0.02 m, DSM 0.04 m, and DTM 0.1 m resolution and cover an area of approximately 0.5 km^2 (Tweedsmuir) and 0.29 km^2 (Hearthstane Burn) at the confluence of the River Tweed and Hearthstane Burn. \n\nThe data were produced as part of the Floods and Droughts Research Infrastructure (FDRI) which is installing monitoring equipment across the Upper Tweed. FDRI is expected to produce repeat surveys of elevation to understand geomorphological change from flood events.\n\nThis work was supported by the Natural Environment Research Council (NERC-UKRI) as part of FDRI. FDRI is a collaborative effort coordinated by the UK Centre for Ecology & Hydrology (UKCEH) in partnership with Imperial College, University of Bristol and the British Geological Survey.","distributionFormats":[{"name":"TIFF","type":"image/tiff","version":"unknown"}],"hasOnlineServiceAgreement":false,"id":"e6ba5b3e-d478-4bff-a665-a09d3e7f8bf0","incomingCitationCount":0,"inspireThemes":[{"theme":"Hydrography","uri":"http://inspire.ec.europa.eu/theme/hy"}],"keywordsInstrument":[{"value":"Remote sensing"}],"keywordsOther":[{"value":"flood","uri":"http://www.eionet.europa.eu/gemet/concept/3298"},{"value":"drought","uri":"http://www.eionet.europa.eu/gemet/concept/2347"}],"keywordsPlace":[{"value":"Upper Tweed"},{"value":"Scotland"},{"value":"Catchment scale"}],"keywordsProject":[{"value":"Floods and Droughts Digital Research Infrastructure (FDRI)","uri":"https://digital.ceh.ac.uk/vocab/ra/5"}],"keywordsTheme":[{"value":"Hydrology","uri":"http://onto.nerc.ac.uk/CEHMD/topic/9"}],"licences":[{"value":"This resource will soon be published and available under the terms of the Open Government Licence","code":"license"}],"lineage":"A number of flights were undertaken across the area using a DJI M350 drone carrying a DJI L2 LiDAR.
