LuT_geo

Product Description

This product allows for transformation from SAR to GROUND coordinates and vice versa. The tables are here given in ground geometry. The ground spacing corresponds to the input DEM spacing and is given in metadata. The SAR pixel coordinates is given for a certain number of looks provided in metadata (parameter Rlooks_unw or Rlooks_int of the processing file nsbas.proc).

The geotiff file has 2 bands:

  • band 1 is the range pixel location of SAR image for each GROUND pixel

  • band 2 is the azimuth pixel location of SAR image for each GROUND pixel

The png file has 1 band:

  • band 1 is range pixel location of SAR image for each GROUND pixel, normalized by a color palette.

(Note: result orduced by task mk_LuT_geo_ in nsb_populate_product.sh; product, preview and metadata are made by nsb_make_data.py)
