1 Mar 2019Envisat and ERS Missions Data Access Guide
The purpose of this document is to help users identify the various types of data that are available from the ENVISAT, ERS-1 and ERS-2 Earth observing satellites, the kind of applications that the data may be used for and, importantly, the practical procedures required for access - including user registration and then search, selection and retrieval or ordering of the data of interest.
