As a further update to the SRTM, I got the German ordering program installed and working although it was not quite intuitive. You have to input the exact dates of the shuttle mission or the search won't find any data. Also, I reported earlier that they had data available in 1m resolution, but that is not entirely true. The vertical resolution is 1m. The horizontal resolution appears to be only about 25m. At 400 Euro per 1/4 degree tile, I'm not sure this is a great deal. I guess it would take a large amount of pressure to get NIMA to release the rest of the world in 30m. Oh, well.
