For developers, GeoIQ has released the stylesheets and code to create the Acetate tiles. Read more about it on our announcement blog post.Getting Started
Acetate is built upon the Tilestache, Mapnik projects and it uses a combination of PostGIS and Shapefiles to store spatial data. The data used is OpenStreetMap, Natural Earth and some custom data sources. The two custom data sources are created through a process of “simulated annealing.”Data Needed
In order to get started with the data install PostGIS and download the OpenStreetMap Planet File. You’ll need to use OSM2PGSQL to import it. The process of importing for the whole world can take a while, if you only need a specific country you might want to grab a country specific extract from GeoFabrik. To get the coastline information you’ll need to get the data from Natural Earth.
The custom data is for place names and simplified motorways. You can download the place name shapefiles from here. The simplified motorways is a SQL script that should be run after the OSM Planet is imported.
Software Needed
To get yourself going install Tilestache from Github. From the README Mapnik is listed as an optional dependency but for our purposes you need it.
At the moment we give you all the pieces to roll your own, though look for a full tutorial in the coming weeks.
Installing Acetate
This step is about just placing the acetate project into a web accessible place. Drop them the project into a web dir and start making tiles….
Modifying the Styles
The styles don’t suite your needs the Cascadenik files are here in a separate repository.
