I just had a look at the tiles near me, and there's quite a bit of noise and obvious artefacts - unless there really is a 2000m tower about 180m across that I've not noticed in the middle of the countryside! I've not compared with SRTM yet... Barry _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
