[GIS] Reading palsar k&c 50 data in GDAL or other open source application

gdalradar

I posted this inquiry in the grass-user list.

JAXA is providing free access to PALSAR 50m Orthorectified K & C Mosaic. According to the website, data are provided in:

Data files (Raw format) and image files (PNG format)

However, I can't get GDAL to access the data (Raw format). I've tested other sample PALSAR data and GDAL can easily access them using the PALSAR driver

I'm looking for open source apps that can read and export this data to the more common raster formats like geotiff, etc.

The header file is described in this pdf: http://www.eorc.jaxa.jp/ALOS/en/kc_mosaic/map/PALSAR_MSC_dsc.pdf

UPDATE: I found a non-foss application that can directly read the kc_mosaic format. It is called MapReady developed by the Alaska Satellite Facility. It can convert to various image format including geotiff.

Another tool is the Next ESA SAR Toolbox (NEST). However testing with NEST4C-1.1, the data format is not recognized.

Not sure if the below is suitable. It's free (but not opensource as far as I can tell):

http://earth.eo.esa.int/polsarpro/about.html

It supports

ALOS PALSAR: dual pol and quad pol (level 1.1 and 1.5 - JAXA CEOS and ERSDAC-Vexcel)

It includes a tool to:

Create BMP files from binary data (modulus, phase, real part, imaginary part) with different colourmaps (grey, jet, hsv);

From bitmap you can then convert to anything.
