This main objective encloses different sub-objectives to\r\n1/ assess the performance of hyperspectral stress related indices (e.g. PRI) for estimating the water stress levels in the citrus orchards under investigation \r\n2/estimate the fluorescence signal at the field level to assess if the fluorescence signal is useful for water stress detection in orchards \r\n3/test and validate a spatial unmixing algorithm on real hyperspatial (cm), multispectral UAV images and hyperspectral airborne data\r\n\r\nStart date of project: 05-09-2011\r\nEnd date of project: 16-03-2012","keywords":"HYPERSTRESS, DLR, EUFAR, hyperspectral ","status":"completed","publicationState":"published","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/9185/?format=json"],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/24355/?format=json"],"parentProject":"https://catalogue.ceda.ac.uk/api/v2/projects/6385/?format=json","subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/74363/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/74364/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/74365/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/74366/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105782/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105835/?format=json"]}
