Hi Edmondo,
If I get your question correctly: Resampling data with a spatial resolution of 90m might increase the resolution of the DEM itself , but it will not increase the detail of the data, only the number of pixels in your DEM. For instance, when you downscale an image of 1 x 1 pixel by a factor 2 (both in x and y direction), the new image will consist of four pixels (2x2). Which all have the same value as the original 1 pixel. So although the number of pixels has been increased, the detail remains the same. So in the end there is not much to do about it.

In draping the tif on my dem the resultant map in nviz has a very low quality. I tried changing the resolution of the DEM (r.resamp) in order to have the same than tif, but I didn't obtain improvements. Any advice?
