Hi, Justin
From a display point of view, GRASS, like most GIS packages, doesn't care
about the scale of data, as long as it is in the same projection and
datum. You can set your resolution to the raster map that you are
interested in, and zoom in to any degree you want. Vectors are always
displayed as one pixel wide in the X monitor.
As a user, it is up to you to realize the difference in accuracy implied
by the scale of different data layers. Hope that helps.

Hello all,
We have a raster map and a vector map of the same area (i.e. we want to overlay
the vector onto the raster). However, they are at different scales. The raster
map is at a scale of 1:1000 while the vector map is at a scale of 1:2400. Since
the raster map is an image, we do not want to lose any details of the image.
Therefore, I was wondering if there was any way to scale the vector map to a
1:1000 scale.Any information would be great since there doesn't seem to be a vector command
to do this.--
