    PAZ ESA archive

    The PAZ ESA archive collection consists of PAZ Level 1 data previously requested by ESA supported projects over their areas of interest around the world and, as a consequence, the products are scattered and dispersed worldwide and in different time windows. The dataset regularly grows as ESA collects new products over the years. Available modes are: StripMap mode (SM): SSD less than 3 m for a scene 30 km x 50 km in single polarization or 15 km x 50 km in dual polarisation ScanSAR mode (SC): the scene is 100 x 150 km2, SSD less than 18 m in signle pol only Wide ScanSAR mode (WS): single polarisation only, with SS less than 40 m and scene size of 270 x 200 km2 Spotlight modes (SL): SSD less than 2 m for a scene 10 km x 10 km, both single and dual polarization are available High Resolution Spotlight mode (HS): in both single and dual polarisation, the scene is 10x5 km2, SSD less than 1 m Staring Spotlight mode (ST): SSD is 25 cm, the scene size is 4 x 4 km2, in single polarisation only.   The available geometric projections are: Single Look Slant Range Complex (SSC): single look product, no geocoding, no radiometric artifact included, the pixel spacing is equidistant in azimuth and in ground range  Multi Look Ground Range Detected (MGD): detected multi look product, simple polynomial slant-to-ground projection is performed in range, no image rotation to a map coordinate system is performed Geocoded Ellipsoid Corrected (GEC): multi look detected product, projected and re-sampled to the WGS84 reference ellipsoid with no terrain corrections Enhanced Ellipsoid Corrected (EEC): multi look detected product, projected and re-sampled to the WGS84 reference ellipsoid, the image distortions caused by varying terrain height are corrected using a DEM.   The following table summarises the offered product types.
