[GRASSLIST:6361] nviz and resolution of GRASS region

GRASS GRASS user
1

Dear users,

I visualize a DEM with nviz and wonder if the grid resolution and
polygon resolution refer to the resolution I defined with g.region in
GRASS 6.0?
For example: the resolution in GRASS 6.0 is 90m.
If I define the grid resolution with 1, does this mean 1unit=90m or 1m?

Thanks in advance
Larissa

It means AFAIK
1: original (current) resolution, here 90m
2: 2 times oversampling, here 2 * 90 = 180m (so lower visual resolution)
3: 3 times oversampling, here 3 * 90 = 270m
etc.

NVIZ always depends on the current region settings for
raster data as (almost) all of the raster related modules.

Hope this helps
