[GRASS-user] Changing/Applying appropriate raster colors

Hi all!

I use ‘i.maxlik’ for image classification. The output obtained shows water in green, built-up area in blue, vegetation in red and so on. It would be appropriate if water appears blue and I had the ability to customize other colors. Where and how do I specify these details in my sequence of operations which is as follows:

  1. Vector layer containing training sites imported from QGIS

  2. Conversion of vector to raster

  3. Generation of signature sites using i.gensig

  4. Classification using i.maxlik
    I tried adding a column(inputs ‘varchar’) “color” with RRR:GGG:BBB values to my vector generated in first step but the colors didn’t come according to that in the final output.

Thanks and regards,

Chethan S.

Use r.colors at the end of your sequence to assign the desired color table.
