Hi Carsten, noo, that isn't the night design :). I used http://ati.land.cz/gps/typdecomp/editor.cgi to verify. But as I got your attention, now, I would like to tell you a few hints on how to optimize the OSM maps as they are a real PITA for drawing and to look at. * The basemap is really bad. Isn't there a possibility to draw at least country borders and major highways? * Tile size. Why so many small tiles? That is one part of the mess in the basemap. And it's a real performance hit to render. I really recommend to have a look at City Navigator on how to tile the world in a sane way. There is no problem to handle files with 10 - 20 MB. But I have to do overhead for each file. Thus many small files are worse than big ones. * Spend more zoom levels in the basemap. Only one is sparse and for the outer zoom levels the basemap is enough. Right now I have to parse a huge amount of files for outer zoom levels. Look, these are the zoom levels for City Navigator Europe V8: Bits Level useBaseMap Basemap 13 4 true 15 3 true 17 2 true Tiles 19 2 false 21 1 false 23 0 false And these are the ones for OSM Europe: Basemap 13 6 true Tiles 16 4 false 18 3 false 20 2 false 22 1 false 24 0 false * Another huge performance hit are staircase lines in the outer zoom levels. I have to re-project every polyline point. That is expensive. If the highway does not change the average direction it can be interpolated by a line. No one expects GPS accuracy on that level. It's just for overview. * Also highways seem to have all their ramps up to the outer zoom levels. That does not add any information. But eats up resources. * Every minor water body seems to be drawn in the outer zoom levels. That does not add information either. Big lakes and major streams are enough. * Tiles must not overlap. Tile selection is really bad if they do. * Use POIS for city names instead of points and add more on every zoom level. Users will be grateful. Ok list is long enough for now. :) Oliver ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ QLandkarte-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/qlandkarte-users
