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