Melbourne map

Provides a configuration to launch your own retina ready map renderer.

Run it

$ ./download.sh
$ docker-compose build
$ docker-compose up

It will take a while for a first start (up to 10 mins) because of DB import. You will know that renderer is ready to use when see logs like this:

postgis_1   | LOG:  autovacuum launcher started
renderer_1  | Starting renderer

renderer_1  | 2016/12/27 23:34:35 main.go:103: [INFO] Starting on %s... :8090

Then you can open example in your favourite web browser:

http://localhost:8888

The initial rendering may take 10-30 seconds, after which you will see a fabulous map of Melbourne city.

Renders other areas

You will need to update postgis image to render other city/area:

• Update postgis/Dockerfile by adding different pbf file to container

  wget https://s3.amazonaws.com/metro-extracts.mapzen.com/melbourne_australia.osm.pbf

• Update postgis/initdb-postgis.sh to use a new file

  osm2pgsql --style /openstreetmap-carto/openstreetmap-carto.style -d gis -U postgres -k --slim /melbourne_australia.osm.pbf

Using custom style

This project is using forked version of openstreetmap-carto style that optimised for hi-res displays.

There are two places that you have to tweak to use different style:

• postgis/initdb-postgis.sh is using style during DB import (--style option):

  osm2pgsql --style /openstreetmap-carto/openstreetmap-carto.style -d gis -U postgres -k --slim /melbourne_australia.osm.pbf

• renderer/map_data/config.json defines style on line 72:

  "Cmd": ["/gopnik/bin/gopnikslave", 
  "-stylesheet", "/openstreetmap-carto/stylesheet.xml", 
  "-pluginsPath", "/usr/lib/mapnik/2.2/input", 
  "-fontsPath", "/usr/share/fonts", "-scaleFactor", "2"],

Update database

You can update database by removing data volume and restart containers:

$ ./clean.sh
$ docker-compose up
