Here is a link to the world map with country boundaries which was discussed on the list in September last year, updated for R >= 2.4. http://spatial.nhh.no/R/etc/world_countries_24.rda load("world_countries_24.rda") You'll need to subset the object to choose the countries of Europe that you require, then use the spTransform() method in rgdal to go to the standard EU Lambert AEA: CRS("+init=epsg:3035") Hope this helps, Roger > Just a few quick questions: > > About the best or appropriate projection for Europe, I am thinking to > use lambert conformal conic or lambert azimuthal equal area.
