[GRASS-user] To change DEM resolution

GRASS GRASS user
1

I’ve a DEM with 90m m res. (from CGIAR SRTM) and I need drape over it a map tif (resolution 1m).

Seeing the resultant map in NViz the quality is very low. I suppose it depends from the different resolutions.
There is a way to change the DEM resolution?

Thanks

Regards

if you are using GRASS64, check out r.resamp.interp, otherwise r.bilinear
should do the trick.

Cheers,
