I have a tiff file containing raster data of land use land cover (LULC) classes.

Each pixel has a pixel value in the form of RGB values of the corresponding LULC class, need to change the pixel values of certain regions on the map and make a new map with revised LULC classification.

How can I do that in ArcGIS Desktop?

  • Are you trying to reclassify single pixels, or entire categories (like combining "wheat" and "soy" into "crop")? Commented Sep 16, 2018 at 0:58

The Reclassify or Conditional tools will help you is you are trying to reclassify an entire category of pixels.

If you want to reclassify individual pixels there isn't a clean way to do it in ArcGIS, but you could look at this thread for some work arounds.

  • Thanks for the answer. But I did it in a different way without using ArcGIS. Commented Sep 17, 2018 at 10:23
