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

OpenMapTiles is an extensible and open tile schema based on the OpenStreetMap. It is used to generate vector tiles for online zoomable maps. The project is about creating a beautiful basemaps with general layers that contain topographic information. More information [openmaptiles.org](https://openmaptiles.org/) and [openmaptiles.com](https://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. Feel free to fork the repo and experiment. The repository is built on top of the [openmaptiles/openmaptiles-tools](https://github.com/openmaptiles/openmaptiles-tools) to simplify vector tile creation.

Please keep in mind that OpenMapTiles schema should stay displaying general topographic content. In case of creating a new layer or expanding an existing one with a specific theme, please create a fork and invite other community members to cooperate on your topic in this separate fork. OpenMapTiles schema is used in many projects all over the world and the size of the final vector tiles needs to be considered in any update.

## Styles

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

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.

- 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+.

### 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 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://osmdata.openstreetmap.de/), [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 data](https://github.com/openmaptiles/import-osm) 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 `make import-sql`.

```
make clean && make && make 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
```
