I don't see why we need to store elevation data for the whole world in the database anyway. I wouldn't think elevation data would be a typical subject for user-submitted modifications related to wide areas. If more detailed structures are desired than provided by the DEM data, corrective contour data for small areas could be stored in the database and be combined with the official DEM data, which could be stored outside the database.
I converted a chunk of SRTM data to 10m interval contours, and overlaid this on an ordnance survey map (using mapserver) - the results are actually incredibly close - the 0 point of the two datasets is obviously slightly different, but the two datasets fit together remarkably well - Obviously I have no idea how good the data is for the rest of the world, but the UK data seems surprisingly accurate, which leads me to my question - is there really such a huge problem with our source data, or do we just need to be generating scenery with more polygons?
