[Gdal-dev] Possible enhanced NetCDF support in GDAL

[A.Th.C. Hulst]

Hi Paavo,

I've looked at your code. Since version 1.2.6 the netCDF driver had quite some 
changes. For instance, it takes care of the geometric dimensions for you now. 
That code can be skipped. As I said before, I've also modified it so that it 
support scale and offset. Unfortunately, I've used a similar trick as you did 
to recast the pImage, so that would complicate things a bit. My 
netcdfdataset.cpp can be found in the trac system of gdal 
(http://trac.osgeo.org/gdal/ticket/1660). 

What do you think would be the best way to reimplement your code in the 1.4.x 
driver? It seems logical to me that only color information is configured in 
the XML file. All other information is included in the netCDF file itself and 
should be obtained from there (geometrics, noDataValues etc.).

It might be an idea to put as much code as possible in a seperate file so we 
only have to update the bindings when a new version arrives.
