Data recorded in the field were processed in Post-Processed Kinematic mode, which means that the accurate positions of the points on the perimeter were not calculated in real time, but raw Global Navigation Satellite System logs were processed afterwards.\nStandard deviations give calculated accuracy of post-processed points. Sudden increases in standard deviation to ~0.01 m horizontal and ~0.04 m vertical show points that were recorded during failures of the base station power. Differential accuracy was achieved for these points by tying them to the British Isles continuous GNSS Facility (BIGF) station at Braemar, 19 km away, instead.\n","metadataDate":"2026-06-29T16:51:28","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/81d05a77-4c95-4f17-bdbf-4c0a0095db6d","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/81d05a77-4c95-4f17-bdbf-4c0a0095db6d.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Essery","givenName":"R.","organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"pointOfContact","email":"richard.essery@ed.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-1756-9095","fullName":"Essery, R.","pointOfContact":"University of Edinburgh"}],"publicationDate":"2024-07-10T00:00:00.000Z","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/81d05a77-4c95-4f17-bdbf-4c0a0095db6d"},{"code":"10.5285/81d05a77-4c95-4f17-bdbf-4c0a0095db6d","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Essery","givenName":"R.","organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"pointOfContact","email":"richard.essery@ed.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-1756-9095","fullName":"Essery, R.","pointOfContact":"University of Edinburgh"},{"familyName":"Essery","givenName":"R.","organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"author","email":"richard.essery@ed.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-1756-9095","fullName":"Essery, R."},{"familyName":"Howe","givenName":"L.","organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"author","email":"leam.howe@ed.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-2888-8761","fullName":"Howe, L."},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"rightsHolder","email":"richard.essery@ed.ac.uk"}],"rightsHolders":[{"organisationName":"University of Edinburgh","organisationIdentifier":"https://ror.org/01nrxwf90","role":"rightsHolder","email":"richard.essery@ed.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"},{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"0.0001"}],"temporalExtents":[{"begin":"2023-06-19","end":"2023-07-28"}],"title":"Global Navigation Satellite System (GNSS) survey of Ciste Mhearad snow patch perimeter, Cairngorm, Scotland, 2023","topicCategories":[{"value":"environment","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment"}],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/81d05a77-4c95-4f17-bdbf-4c0a0095db6d","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
