[gdal-dev] JAXAPalsar 1.0 & 1.1 extended metadata reading support

[Rodolfo Bonnin]

Hello Antonio,

I'll read the specs regarding JaxaPalser type, out software is reading those
and they look well, but I didn't analyze the format in detail. I've also
added georeferencing (Calculating the affine transform based on the 4
corners and assigning a coordinate system (WGS84 instead of ITRF97 at the
moment as we are based on 1.8.0) to the JaxaPalsar driver.

For the time being, I'm writing new drivers for the PRISM and AVNIR2
sensors, based on the current JaxaPalsar driver, as we are constrained in
time, but I think that once I send the code, the diffing could be useful
when writing the new unified driver. I'm ready to collaborate if you think
another approach could more useful. The idea is to have PRISM and AVNIR2
support ASAP.

Regards,
Rodolfo Bonnin.
