Will osm2po or other tools simplify links between nodes? OK, thanks for a great answer. I follow the reasoning which I had not thought of before. osm2po is a great product to use. |

Using the PgRouting driving_distance function can we see the edges? Sorry about the terribly late reply. I left this field for a while. I cannot really remember. I gave up and started using a Dijkstra algorithm directly with the python language. The routine returns the distance (or time cost, if that is how you weight the links/edges) of every visited node back to the source as well as every nodes predecessor node. i.e.code.activestate.com/recipes/… |

Best design for Open Source Python / PostGIS prototype The other thing I've just found out is that returning rows via a stored procedure is very, (very, very) slow. |

Best design for Open Source Python / PostGIS prototype Thanks, David. That sounds like a good policy which I've been drifting towards myself. I'll look into GeoServer for image tiles. I've used python/mapnik in the past for this. |

Best design for Open Source Python / PostGIS prototype More generally I'm looking to settle on an architecture that balances quite intensive geo-processing with a responsive web user interface: not as quick as Google of course, but recognizable in terms of today's user expectations! This is for a few power users. |

Best design for Open Source Python / PostGIS prototype Matthew - I am trying to create drivetime polygons. I know something about concave polygons but wanted to try it this way, primarily for better accuracy. The polygons are 200m buffers of MultiLinestrings (that is: roads). I am currently playing with the idea of pre-buffering all of the roads in the database, but I still need to merge them. \n # |
