Dear Researchers,
with a low-pass guassian filter with a kernal mask of 3x3 pixel, I need to
test several "sigma" value (i.e. 1, 2, and 4 or eventually different
values) using "raster" library to understand the better smoothing for a
further segmentation algorithm

Hmm, the subject "multidimensional" got me thinking of "rasterized"
vector layers, but I think that was off-track.
You can use gSimplify in the rgeos package to easily simplify a
Spatial[Lines/Polygons]DataFrame as read in by readShapeSpatial
(maptools) or readOGR (rgdal) (or coerced from some oth

This is a pretty open question, and there are certainly things you
could do in R but I wonder if you'd be better looking elsewhere.
Using GDAL gives you a lot of support for pre-rendered scales and
tiled data sets, and the GDAL library has tools for rasterizing from
vector layers. Also, mapserver

Hello,
I have some shapefiles which I would like to render on a map with
different scales with my own software. Is there
a way to precreate vector layers (somewhat aggregated) for each map
scale for the given shapefile in order to reduce the volume of data
