Treating Raster data like vector data where we can edit or modify the data in pixel level has been a dream. This kind workflow actually can be done in older GIS or Remote Sensing software like ILWIS, but in QGIS this functionality has just been released. You can edit or modify the pixel values using few options, pixel by pixel, based on region selection, based on rectangle selection or few more selection options. Commonly alteration of raster pixel values only can be done thru map algebra or raster calculator.  It is all with a single goals, to make the raster data are easier to manage and update. But this functionality has a weakness, it gives people chance to manipulate pixels value that previously hard to do without raster calculator/algebra. Everything always come with pros and cons, that is just natural. \ So for you who looking for a way to edit raster directly on a pixel by pixel basis or using more batch selection method, tutorial below is designed to helps you with that kind o
