Re: [gdal-dev] add string field to img

Derek,

You can add this info as meta-data tags. You will have to define your own
names for the keys. Something like pix_1_class, pix_2_class, etc.

To add these you can use the -mo option with gdal_translate[1] or use a vrt
file[2]. You can create such a vrt file using gdal_translate too by setting
the output format (-of) to VRT.

[gdal-dev] add string field to img

[jdmorgan]

Hello,
I was hoping someone could help me out.  I have a raster .img file. with 
existing pixel values.  Those values are integer, but are classed to 
string values not currently in the same .img file.  For example pixel 
value 2 means ClassTwo. Is it possible to add the string values (a new 
field) onto the raster .img file?


Thanks,
Derek
