I have some MODIS data processed with MRT tools. They are now in tiff format. Now, I have to complete Density slicing to identify water pixels from the image. The DN higher than 1985 is usually non-innundated area where lower than that value is the inundated area. I completed the task with ILWIS but want to do that with QGIS. Is it possible to do that? Water pixel will be red color and non-inundated area will be green color.
