Re: [gdal-dev] Gdal_translate, question from an amateur.

I'm not sure I fully understand the question. Are you attempting to convert all pixels with RGB value 72, 255, 25 to white? Or are you trying to scale the image to 8-bit? Sounds like the former. In this case -scale is not the way to go. I'm honestly not sure what is, short of reading each band

Re: [gdal-dev] subdatasets not read in a HDF file

1) Not sure, but give it a try! If not, put it somewhere accessible on the web. You should definitively create a ticket for this. 2) netcdf supports HDF4 if it was configured for hdf4 support. In that case, to force the netcdf driver you would have to use "NETCDF:filename:subdataset", or else th

[gdal-dev] Re: ogr2ogr different behaviour on different OS platforms (Windows 7 vs XP)

Hi, Thanks, yes the warning was my fault, missing -nln option. The creation table error happens intermittently, could potentially caused by wrapping ogr2org execution from a C# thread. Any pointers/advices on how to make this call more reliable are much appreciated. Thanks - H On Fri, Oct 21,
