(The ArcticDEM is an NGA-NSF public-private initiative to automatically produce a high-resolution, high quality, digital surface model (DSM) of the Arctic using optical stereo imagery, high-performance computing, and open source photogrammetry software.)\r\n\r\nAll data were compiled and filtered in a semi-automated approach, using a modified version of the MEaSUREs GIMP ice mask (https://nsidc.org/data/NSIDC-0714/versions/1) to clip the dataset to within 1 km of the ice margin. Each detected lake was then verified manually.","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}],"acquisitionComponent":[{"ob_id":32166,"independentInstrument":[],"instrumentplatformpair_set":[{"ob_id":12444,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/12319/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/12313/?format=json","relatedTo":{"ob_id":32166,"uuid":"ffb464db0cd64ad0984d750d68563bcb","short_code":"acq"}},{"ob_id":12446,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/13187/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/13182/?format=json","relatedTo":{"ob_id":32166,"uuid":"ffb464db0cd64ad0984d750d68563bcb","short_code":"acq"}},{"ob_id":12447,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/25277/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/13182/?format=json","relatedTo":{"ob_id":32166,"uuid":"ffb464db0cd64ad0984d750d68563bcb","short_code":"acq"}},{"ob_id":12445,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/20017/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/12313/?format=json","relatedTo":{"ob_id":32166,"uuid":"ffb464db0cd64ad0984d750d68563bcb","short_code":"acq"}}]}],"identifier_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/143013/?format=json"]}
