About

This is a fork of the original MapOSMatic service. The source for this fork can be found on GitHub:

If you want to try to run your own instance you may want to check out my Vagrant test setup as a starting point

Below you'll find the "About" text of the original MapOSMatic project.

History

MapOSMatic has been started thanks to an idea of Gilles Lamiral, an OpenStreetMap and free software contributor of Rennes area, France. From his idea, a group of crazy hackers met together during a one-week Hackfest in August 2009 and brought the idea of Gilles Lamiral to life by writing the code and named the project MapOSMatic. The group of crazy hackers would like to thank Gilles for sharing his bright idea!

Of course, MapOSMatic is fully free software, licensed under the AGPLv3.

How does it work?

On our server, we run a PostgreSQL server, with the PostGIS extension. In this PostgreSQL server, we have loaded the OpenStreetMap data for the whole world using the osm2pgsql tool. The same tool is also used to apply daily differences of the database, which allows to keep it up to date with the new contributions of OpenStreetMap users.

For the map rendering, we use the famous Mapnik with the OpenStreetMap stylesheet available in OpenStreetMap Subversion repository. Using Mapnik and Cairo, we built OCitySMap, a Python module that:

This Python module can be used through a command-line tool provided with OCitySMap, so everyone can run its own city-map rendering suite. However, as the installation of the different components is quite complicated, a small web service has been created on top of it so that end-users can easily generate and use OpenStreetMap city maps.

This web service has been called MapOSMatic, like map-o-matic but with a reference to OpenStreetMap (OSM). The web service is written in Python using Django. It is responsible for storing the rendering requests and displaying the result of these requests. The rendering itself takes place asynchronously through the maposmaticd daemon. This daemon does only one rendering at a time, which is very important because of the CPU and I/O intensive nature of the map rendering process.

For the city search engine, we use the wonderful Nominatim service. This service made it really simple to provide a nice search engine that allows to select between multiple cities of the same name, by providing informations on the city location.

Contributing

As stated above, both OCitySMap and MapOSMatic are fully free software, so you're invited to contribute. Here are the few starting points to help us:
