## OpenMapTiles [](https://github.com/openmaptiles/openmaptiles/actions)
|
|
|
|
OpenMapTiles is an extensible and open tile schema based on the OpenStreetMap. This project is used to generate vector tiles for online zoomable maps. OpenMapTiles is about creating a beautiful basemaps with general layers containing topographic information. More information [openmaptiles.org](https://openmaptiles.org/) and [maptiler.com/data/](https://www.maptiler.com/data/).
|
|
|
|
We encourage you to collaborate, reuse and adapt existing layers, or add your own layers. You may 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 display general topographic content. If creating a new layer or expanding an existing layer with a specific theme, please create a fork and invite other community members to cooperate on your topic. 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.

## 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+.
|
|
|
|
### Microsoft Windows Subsystem for Linux (WSL)
|
|
|
|
Please use Linux `/home/user/` directory, not Windows e.g. `/mnt/c` directory.
|
|
|
|
### Build
|
|
|
|
Build the tileset.
|
|
|
|
```bash
|
|
git clone https://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 to automatically download and import given area. If area is not given, Albania will be imported. List of available areas `make list-geofabrik`.
|
|
|
|
```
|
|
./quickstart.sh <area>
|
|
```
|
|
|
|
### Prepare the Database
|
|
|
|
Now start up the database container.
|
|
|
|
```bash
|
|
make start-db
|
|
```
|
|
|
|
Import external data from [OpenStreetMapData](http://osmdata.openstreetmap.de/), [Natural Earth](http://www.naturalearthdata.com/) and [OpenStreetMap Lake Labels](https://github.com/openmaptiles/osm-lakelines). Natural Earth country boundaries are used in the few lowest zoom levels.
|
|
|
|
```bash
|
|
make import-data
|
|
```
|
|
|
|
Download OpenStreetMap data extracts from any source like [Geofabrik](http://download.geofabrik.de/), and store the PBF file in the `./data` directory. To use a specific download source, use `download-geofabrik`, `download-bbbike`, or `download-osmfr`, or use `download` to make it auto-pick the area. You can use `area=planet` for the entire OSM dataset (very large). Note that if you have more than one `data/*.osm.pbf` file, every `make` command will always require `area=...` parameter (or you can just `export area=...` first).
|
|
|
|
```bash
|
|
make download area=albania
|
|
```
|
|
|
|
[Import OpenStreetMap data](https://github.com/openmaptiles/openmaptiles-tools/blob/master/bin/import-osm) with the mapping rules from
|
|
`build/mapping.yaml` (which has been created by `make`). Run after any change in layers definition (any change in `mapping.yaml`).
|
|
|
|
```bash
|
|
make import-osm
|
|
```
|
|
|
|
Import labels from Wikidata. If an OSM feature has [Key:wikidata](https://wiki.openstreetmap.org/wiki/Key:wikidata), OpenMapTiles check corresponding item in Wikidata and use its [labels](https://www.wikidata.org/wiki/Help:Label) for languages listed in [openmaptiles.yaml](openmaptiles.yaml). So the generated vector tiles includes multi-languages in name field.
|
|
|
|
This step uses [Wikidata Query Service](https://query.wikidata.org) to download just the Wikidata IDs that already exist in the database.
|
|
|
|
```bash
|
|
make import-wikidata
|
|
```
|
|
|
|
### Work on Layers
|
|
Each time you modify a layer's `mapping.yaml` file or add new OSM tags, run `make` and `make import-osm` to recreate tables (potentially with additional data) in PostgreSQL. With the new data, there can be new Wikidata records also.
|
|
```
|
|
make clean
|
|
make
|
|
make import-osm
|
|
make import-wikidata
|
|
```
|
|
|
|
Each time you modify layer SQL code run `make` and `make import-sql`.
|
|
|
|
```
|
|
make clean
|
|
make
|
|
make import-sql
|
|
```
|
|
|
|
Each time you make a modification that adds a new feature to vector tiles e.g. adding new OSM tags, modify the layer
|
|
style snippet by adding new style layer so the changes are propagated visually into the style.
|
|
All new style layers must have the `order` value which determines the order or rendering in the map style.
|
|
After the layer style snippet is modified run:
|
|
```bash
|
|
make build-style
|
|
```
|
|
|
|
|
|
|
|
Now you are ready to **generate the vector tiles**. By default, `./.env` specifies the entire planet BBOX for zooms 0-7, but running `generate-bbox-file` will analyze the data file and set the `BBOX` param to limit tile generation.
|
|
|
|
```
|
|
make generate-bbox-file # compute data bbox -- not needed for the whole planet or for downloaded area by `make download`
|
|
make generate-tiles-pg # generate tiles
|
|
```
|
|
|
|
### Workflow to generate tiles
|
|
If you go from top to bottom you can be sure that it will generate a .mbtiles file out of a .osm.pbf file
|
|
```
|
|
make clean # clean / remove existing build files
|
|
make # generate build files
|
|
make start-db # start up the database container.
|
|
make import-data # Import external data from OpenStreetMapData, Natural Earth and OpenStreetMap Lake Labels.
|
|
make download area=albania # download albania .osm.pbf file -- can be skipped if a .osm.pbf file already existing
|
|
make import-osm # import data into postgres
|
|
make import-wikidata # import Wikidata
|
|
make import-sql # create / import sql functions
|
|
make generate-bbox-file # compute data bbox -- not needed for the whole planet or for downloaded area by `make download`
|
|
make generate-tiles-pg # generate tiles
|
|
```
|
|
Instead of calling `make download area=albania` you can add a .osm.pbf file in the `data` folder `openmaptiles/data/your_area_file.osm.pbf`
|
|
|
|
To change the name of the output filename, you can modify the variable `MBTILES_FILE` in the `.env` file or set up the environment variable `MBTILES_FILE` before running `./quickstart.sh` or `make generate-tiles-pg` (e.g., `MBTILES_FILENAME=monaco.mbtiles ./quickstart.sh monaco`).

Products or services using maps derived from OpenMapTiles schema need to **visibly credit "OpenMapTiles.org"** or **reference "OpenMapTiles"** with a link to https://openmaptiles.org/. Exceptions to attribution requirement can be granted on request.
|
|
|
|
For a browsable electronic map based on OpenMapTiles and OpenStreetMap data, the
|
|
credit should appear in the corner of the map. For example:
|
|
|
|

|
|
|

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.
