[gdal-dev] Help with color map for raster grid

[Chaitanya kumar CH]

Daniel,

You can make changes in two places. In the data or the display engine. In
the data, you can modify the colour table. This will be permanent. In the
display, you just load a different color table based on the table of pixel
values. If you don't like either, you can build a gdal vrt file and modify
its colour table.
