Thanks francissimo
You are right, The labels are a little bit big because the real size of the map is atound 12 cm. So the labels need to have a size of 7 pt to be readable since it was a map for GEO magazine. Limits of size �� When publishing. Thats why in the web page it lacks a little bit of resolution, even at 600 ppp.

The GIS I use are QGIS, or gvsig or arcgis, depending on the job. Mainly QGIs. For the 3d a very old software.. WCS
