## OpenMapTiles [![Build Status](https://travis-ci.org/openmaptiles/openmaptiles.svg?branch=master)](https://travis-ci.org/openmaptiles/openmaptiles)

OpenMapTiles is an extensible and open vector tile schema for a OpenStreetMap basemap. It is used to generate vector tiles for [openmaptiles.org](http://openmaptiles.org/) and [openmaptiles.com](http://openmaptiles.com/).

We encourage you to collaborate, reuse and adapt existing layers and add your own layers or use our approach for your own vector tile project. The repository is built on top of the [openmaptiles/tools](https://github.com/openmaptiles/openmaptiles-tools) to simplify vector tile creation.

## Styles

You can start from several GL styles supporting the OpenMapTiles vector schema.

- [Positron](https://github.com/openmaptiles/positron-gl-style)
- [Dark Matter](https://github.com/openmaptiles/dark-matter-gl-style)
- [Klokantech Basic](https://github.com/openmaptiles/klokantech-basic-gl-style)
- [Klokantech 3D](https://github.com/openmaptiles/klokantech-3d-gl-style)
- [Fiord Color](https://github.com/openmaptiles/fiord-color-gl-style)
- [Toner](https://github.com/openmaptiles/toner-gl-style)

We also ported over our favorite old raster styles (TM2).

## Schema

OpenMapTiles consists out of a collection of documented and self contained layers you can modify and adapt.
Together the layers make up the OpenMapTiles tileset.

## Develop

To work on OpenMapTiles you need Docker and Python.

- Install [Docker](https://docs.docker.com/engine/installation/). Minimum version is 1.12.3+.
- Install [Docker Compose](https://docs.docker.com/compose/install/). Minimum version is 1.7.1+.
- Install [OpenMapTiles tools](https://github.com/openmaptiles/openmaptiles-tools) with `pip install openmaptiles-tools`

### Build

Build the tileset.

```bash
git clone git@github.com:openmaptiles/openmaptiles.git
cd openmaptiles
# Build the imposm mapping, the tm2source project and collect all SQL scripts
make
# You can also run the build process inside a Docker container
docker run -v $(pwd):/tileset openmaptiles/openmaptiles-tools make
```

You can execute the following manual steps (for better understanding)
or use the provided `quickstart.sh` script.

```
./quickstart.sh
```

### Prepare the Database

Now start up the database container.

```bash
docker-compose up -d postgres
```

Import external data from [OpenStreetMapData](http://openstreetmapdata.com/), [Natural Earth](http://www.naturalearthdata.com/) and  [OpenStreetMap Lake Labels](https://github.com/lukasmartinelli/osm-lakelines).

```bash
docker-compose run import-water
docker-compose run import-natural-earth
docker-compose run import-lakelines
docker-compose run import-osmborder
```

[Download OpenStreetMap data extracts](http://download.geofabrik.de/) and store the PBF file in the `./data` directory.

```bash
cd data
wget http://download.geofabrik.de/europe/albania-latest.osm.pbf
```

Import [OpenStreetMap](http://wiki.openstreetmap.org/wiki/Osm2pgsql) data with the mapping rules from
`build/mapping.yaml` (which has been created by `make`).

```bash
docker-compose run import-osm
```

### Work on Layers

Each time you modify layer SQL code run `make` and `docker-compose run import-sql`.

```
make clean && make && docker-compose run import-sql
```

Now you are ready to **generate the vector tiles**. Using environment variables
you can limit the bounding box and zoom levels of what you want to generate (`docker-compose.yml`).

```
docker-compose run generate-vectortiles
```

Products or services using maps derived from OpenMapTiles schema need to visibly credit "OpenMapTiles.org" or reference "OpenMapTiles" with a link to http://openmaptiles.org/. Exceptions to attribution requirement can be granted on request.

For a browsable electronic map based on OpenMapTiles and OpenStreetMap data, the

For printed and static maps a similar attribution should be made in a textual
description near the image, in the same fashion as if you cite a photograph.
