Hi all,I was just wasting the last two days fiddling around this problem. I ended up using maptools and PBSmapping with SpatialLines2PolySet() and then PolySet2SpatialPolygons() to work around this problem. I don't know why this has to be so complicated. But I was also struggling with different projections, so you might find this solution easy...
Hope this helps. Kami -- Kamran Safi Max Planck Institute for Ornithology Vogelwarte Radolfzell Schlossallee 2 78315 Radolfzell Germany and Institute of Zoology Zoological Society of London Regent's Park NW1 4RY London United Kingdom Henk Sierdsema schrieb:
Hi Hans, Please have a look at paragraph 2.6 (page 41) on spatial polygons in the ASDAR-book. Here you will find an example of converting a shoreline into polygons.

The list represents 8 polygons of a given xlim/ ylim. Now I'd like to convert the list into 8 polygons in order to draw them filled out.I could do it 'manually' and try close these lines heuristically but maybe there's already such a workaround available.Thanks for any hint in advance! --Hans PS The new maptools release is really nice :) Thanks! _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
