I've started to play around with map-generalization (I think, the right English term is simplification with smoothing). This means: Whenever you zoom out of a map, there's lot of details, you don't need at all. The SQL-query grabs all this data of course. Currently, the functions of PostGIS are very limited: Simplications with Douglas-Peuker-algorithm only. So I will start to use GRASS with better algorithms soon. The result will be: Smoothed lines (or curves) with less nodes. These will be faster to grab from DB and the data will be faster to render. The detail gets lost in rendering anyway ;-) _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
