# Data Sources
|

The OSM Vector Tiles contain data from the following data sources.

The OSM Vector Tiles contain data from the different data sources

which are described below.

## OSM Planet File
|
||||
The cornerstone of the entire map is OpenStreetMap data from published snapshots from [OSM Planet](http://wiki.openstreetmap.org/wiki/Planet.osm). The vector tiles contain a subset of the OSM Planet file. [Imposm3](http://imposm.org/docs/imposm3/latest/) is used with a [custom mapping file](https://github.com/osm2vectortiles/osm2vectortiles/blob/master/src/import-osm/mapping.yml) to import the OSM data into the PostGIS database.
|
||||
|
||||
More information about the [layer reference](/docs/imposm-schema.html)
|
||||

Imposm3 creates the following tables in the PostGIS database.

If you need an extract which is not included on the [downloads page](http://osm2vectortiles.org/data/download.html), you can simply download the planet file and make your own extract.

### Export
|
||||
|
||||
For generating the vector tiles the tilelive tool [tl](https://github.com/mojodna/tl) is used which wraps around Mapnik. The data style defines all feature sets (layers) and is transformed into a Mapnik XMLstylesheet by the tilelive-tm2source provider. Tilelive-bridge calls Mapnik with the generated stylesheet and hands the generated data over to node-mbtiles, which stores the vector tiles in a MBTiles container.
