The spotty part is a bug which mostly occurred with the early lowzoom generation.. The low zoom stitcher was not always retrieving valid data and the tile stitcher then inserted an "unknown" tile. I mostly solved this with a quick fix by retrying on error, which gets rid of the blue spots. I will need to investigate the root cause, but this should not be a problem anymore. As for pale, how do you mean that? Are streets not pronouned enough? I recursively stitch together tilesets based on the captionless layer from z6, up to z12, zoom level by zoom level. Might it be that too much data is lost after 6 "stitches"? Hoes does the current lowzoom does it? I will have to look into the darken qualifier thing. It's on my TODO list now. > Perhaps the pale rendering is an intentional change (the old lowzoom > compositing used the "darken" qualifier at each level to increase contrast), > but the blue spots are definitely not a sign of good health. summary: ad 1) on todo list ad 2) mostly fixed. needs more investigation. _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/tilesathome
