A little. P2 has to reproject each point on first load. But we're using an ActionScript port of proj4 and that's pretty efficient. Certainly, for the VMD shapefiles I've been testing, I don't notice any particular overhead on loading; and obviously once it's in, it's in for the rest of your session. > If it is, it may be worthwhile reprojecting all the files.

Frederik, are you there? cheers Richard _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
