This dataset was collected in a collaboration with Texo ( `https://www.texo.co.uk/`_) and Headwall ( `https://www.headwallphotonics.com/`_) using a visible-near infrared (VNIR) sensor (400 - 1000 nm). The purpose of the data collection was to better understand the attenuation of plastic spectral signature in the freshwater environment and the effect of water. .. _`https://www.texo.co.uk/`: https://www.texo.co.uk/ .. _`https://www.headwallphotonics.com/`: https://www.headwallphotonics.com/ Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk originator Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk custodian Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk distributor Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) data.manager@cefas.co.uk owner notPlanned Analysis Freshwater Human impacts GEMET, version 1.0 2008-06-01 publication Anthropogenic contamination SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Habitats and biotopes GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Unknown SeaVoX Vertical Co-ordinate Coverages 2010-05-18 revision Marine Environmental Data and Information Network MEDIN metadata record availability 2012-01-11 publication data.gov.uk MEDIN metadata record availability 2012-01-11 publication otherRestrictions noLimitations otherRestrictions Public data - no limitations to reuse English environment 1.00 1.50 52.50 52.75 2021-08-19 2025-04-11 Unknown https://data.cefas.co.uk/view/21746 Cefas Data Portal information The Cefas Data Portal contains metadata records and data sets available to download and connect to in support of our commitment to open science. dataset INSPIRE Data Specification on Habitats and Biotopes – Technical Guidelines 2013-12-10 publication false See the referenced specification Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 publication true See the referenced specification The raw images were converted to radiance, using a factory-built radiometric calibration in Spectral View version 3.2 software. Consequently a “scene White Reference” was generated using a 56% white calibration panel. Consequently, radiance was converted into reflectance at a spectral resolution of 2.2 nm, resulting in 273 bands, with spectral range between 400 - 1000 nm. The images were orthorectified using a `Digital Elevation Model (DEM)`_and the latitude and longitude associated with every image. This process generated Input GeoMetry, which was used for mosaicking and was exported as an ENVI (.hdr) file. The final orthorectified datacube has a ground sampling distance of ~1.9 cm. The processing of the datacube was conducted by Headwall. .. _`digital elevation model (dem)`: https://srtm.kurviger.de/SRTM30/srtm30_documentation.pdf MEDIN 3.1.1
