Images were obtained using conventional aerial plane photography with a 0.06m ground resolution, captured at a height of c. 1500 m from a fixed-wing aeroplane with an UltraCamXp sensor. \nThe orthomosaic was generated from the aerial photography (using up to 160 individual images for each orthomosaic) by automated image matching using the SfM program Pix4D (https://pix4d.com/) with the ‘large frame’ supplementary software package. Bundle adjustment was undertaken using Pix4D’s key point matching system optimised for aerial nadir imagery. Camera properties were specified using calibration certificates and were not allowed to vary during the calculation. \nThe orthomosaic image file includes UTM Easting and Northing coordinates that can be viewed by opening the image in a GIS or other image handling software.\n\n","metadataDate":"2026-06-29T16:10:05","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/7473d4f9-c9a7-40ad-9f58-e58e25997fc5.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"},{"url":"https://catalogue.ceh.ac.uk/datastore/eidchub/7473d4f9-c9a7-40ad-9f58-e58e25997fc5","name":"Download the data","description":"Download a copy of this data","function":"fileAccess","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Professor","familyName":"Nicholas","givenName":"Andrew","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"a.p.nicholas@exeter.ac.uk","fullName":"Nicholas, A.","pointOfContact":"University of Exeter"}],"publicationDate":"2019-10-29T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"c96218ff-5b47-4a45-9c47-3e5fe62d540c"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/7473d4f9-c9a7-40ad-9f58-e58e25997fc5"},{"code":"10.5285/7473d4f9-c9a7-40ad-9f58-e58e25997fc5","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Ashworth","givenName":"P.","organisationName":"University of Brighton","organisationIdentifier":"https://ror.org/04kp2b655","role":"author","email":"p.ashworth@brighton.ac.uk","fullName":"Ashworth, P."},{"familyName":"Nicholas","givenName":"A.
