The ESA (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 as well as via geographical catalogue search based on area of interest and metadata. Data download is available via HTTPS, including bulk download functionality.
ERS products can also be discovered through ESA's EO Catalogue (EO CAT), 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 FAQ page.
New users can register an account on EO Sign In. For further information about the EO Sign In Service you can visit TellUs.
For internal ESA users the ESAAD account cannot be used.

Collection Description
This ERS Medium Resolution stripline product is generated from the Image Mode Level 0 Product. Stripline image products contain image data for an entire segment, up to a maximum size of 10 minutes per product for IM mode. The processor concatenates together several sub-images called "slices" that were processed separately on a dataset-by-dataset basis in order to form the entire stripline image. The product is processed to an approximately 150 m x 150 m resolution and has a radiometric resolution that is good enough for ice applications. This product has a lower spatial resolution than the SAR_IMP_1P and SAR_IMS_1P products.
Product Characteristics:
- Pixel size: 5 m (ground range – across track) x 75 m (azimuth – along track)
- Scene area: 100 km (range) x at least 102.5 km
- Scene Size: 1300 pixels (range) x at least 1350 lines (azimuth)
- Pixel depth: 16 bits unsigned integer- Total product volume: at least 3.5 MB
- Projection: Ground-range
- Number of looks: 8 (azimuth) x 7 (range).
