[GRASS-user] Vectors in WMS

[Maris Nartiss]

I'm sorry to disappoint You, but WMS deals with raster and not with
vectors. Vectors You can get with WFS or similar service. If You by
word "vectors" mean roads, rivers etc. displayed as raster in WMS
service, then You should:
1) Download data as rasters (r.in.wms);
2) Extract objects of interest (r.mapcalc);
3) Run r.thin to get thin lines;
4) Convert result to vectors with r.to.vect.

Still You can create buffers and other analysis on raster data.

Maris.
