comment Export spatial overlay from R package PBSmapping
I'm rather looking for an union, but with non-overlapping/touching parts left behind. This is your suggested intersection: Intersection ... and this is what i'm looking for: Union The red parts should be maintaned. I have benchmarks myself from both of the libraries, GEOS and GPC, and in my case the Union with GEOS was significant slower (GPC: 5 minutes, GEOS: around 2 days).

"+proj=tmerc +lat_0=0 +lon_0=12 +k=1 +x_0=4500000 +y_0=0 +datum=potsdam +units=m +no_defs +ellps=bessel" ... this is the CRS with which i projected the shapefiles and it's also the output of proj4string.
