No geometry editing needed! I was able to get around this by applying the same styling of the polygons to the polygon outlines as well. #test{ line-width:1; line-opacity:0.4; [fcst<=68]{polygon-fill:#DFF22C; line-color:#DFF22C;} [fcst<=66]{polygon-fill:#BFE526; line-color:#BFE526;} [fcst<=64]{polygon-fill:#9FD81F; line-color:#9FD81F;} ...

I had exact same need and ended up building two tools: tilestrata – Pluggable tile server written in Node.js. There's a mapnik plugin and disk cache. tilemantle – A command-line tool for warming the tile cache. It works by sending HEAD requests to the tileserver. Via a special header it can tell tilestrata to skip the cache and render a new tile. You can ...
