I have DEM (*.tif) from which I need to create shaded relief in GRASS/QGIS. Problem is that it appears to have some parallel stripes all across the raster, as on picture below.

I used resampling method (Warp(Reproject)) to visually increase resolution, and I filtered the raster with GRASS function r.neighbors.

Then I created shaded relief using r.relief and the stripes become more visible.

How can I remove those stripes?

  • There is a QGIS processing tool Destriping in SAGA | Raster Tools. Unfortunately I have no experience with this tool, but an article by SAGA module author SRTM DEM destriping with SAGA GIS may guide you. – Kazuhito Jan 14 '18 at 12:17
