    ICEYE ESA archive collection now available to users

    ICEYE ESA archive collection is now available worldwide through ESA’s Third Party Missions programme. The ESA archive collections consist of products requested by ESA-supported projects worldwide, and, therefore, the products are scattered and dispersed over the territory in different time windows. The datasets regularly grow as ESA collects new products over the years.

    ICEYE ESA archive

    The ICEYE ESA archive collection consists of ICEYE Level 1 products requested by ESA supported projects over their areas of interest around the world. The dataset regularly grows as ESA collects new products over the years. Three different modes are available: Spot: with a slant resolution of 50 cm in range by 25 cm in azimuth that translated into the ground generates a ground resolution of 1 m over an area of 5 km x 5 km. Due to multi-looking, speckle noise is significantly reduced Strip: the ground swath is 30 x 50 km2 and the ground range resolution is 3 m Scan: a large area (100km x 100kmis acquired with ground resolution of  15m Two different processing levels: Single Look Complex (SLC): Level 1A geo-referenced product and stored in the satellite's native image acquisition geometry (the slant imaging plane) Ground Range Detected (GRD): Level 1B product; detected, multi-looked and projected to ground range using an Earth ellipsoid model; the image coordinates are oriented along the flight direction and along the ground range; no image rotation to a map coordinate system is performed, interpolation artefacts not introduced. The following table defines the offered product types: EO-SIP Product Type Mode Processing level XN_SM__SLC Strip Single Look Complex (SLC) - Level 1A XN_SM__GRD Strip Ground Range Detected (GRD) - Level 1B XN_SL__SLC Spot Single Look Complex (SLC) - Level 1A XN_SL__GRD Spot Ground Range Detected (GRD) - Level 1B XN_SR__GRD Scan Ground Range Detected (GRD) - Level 1B
