ESA’s (A)SAR On-the-fly (OTF) data processing and dissemination service allows end-users to gain direct access to the (A)SAR archive from the ERS-1, ERS-2 and Envisat Missions.

The data is collection based and allows data browse and download through the treeview, filename, as well as via geographical catalogue search based on area of interest and metadata. Interferometric search option is available for relevant collections. Data download is available via HTTPS, including bulk download functionality.

ERS products can also be discovered through ESA's Exploring Earth service, which allows users to browse and download products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal).

For information on the (A)SAR On-The-Fly service please refer to the OTF User Manual.

For further information about the EO Sign In Service you can visit TellUs.

Should you need support to access the data, please contact EOHelp.
