Hi friends, Hope you find this mail in good health.
I have created a map rendering application using Mapnik & Python. I have implemented basic operation on map rendering too. The major problem is large time taken by Mapnik to render a map. I am rendering a map by firing queries on postgreSql database & assigning this data to various layers of map & finally rendering map by calling function render_to_file(). I have defined various styles & rules function similar to osm.xml style sheet with filter, maxscale & minscale parameters to filter our data at various zoom level. When I am rendering map using Europe data & it is taking time about 5 to 6 minutes for rendering map image. Again whenever I perform some operation like zoom in, zoom out, pan etc ; it takes same amount of time. Most people recommended tile server as solution to this problem but I can’t use tile server. Because I have to provide “route planning & management” as one of the feature of my project, and I guess this will not be possible using tile server. I guessed using estimate_extent parameter in PostGIS function could help me out of this. But when I tried it skipped most of the data from query result and rendered map with very low details. Could you please help me out of this problem? Please do provide me some concrete solution for this issue. Expecting your helping hands toward me.
