摘要

The Copernicus Coordinated data Quality Control (CQC) service, as part of the Copernicus Space Component Data Access system (CSCDA), has visibility of the whole range of data products provided by the contributing satellite missions to Copernicus users. Through this unique perspective, it has been recognised that there is variability across image providers of orthorectified data. This generates inconsistencies and may cause confusion among EO data users. Currently there is no international agreement as to the terminology to be used to identify a product on the basis of the geometric corrections applied. This may explain the plethora of names and level codes used by Copernicus Contributing Mission Entities (CCMEs) to identify their products. Orthorectification terms, methods and metrics used are not uniform among the various missions, therefore users may have difficulties in identify the right product for their needs. This paper presents the key topics of non-uniformity and the CQC proposal for harmonisation of product terminology.
