# Planetiler Planetiler (_**pla**·nuh·tai·lr_, formerly named "Flatmap") is a tool that generates [Vector Tiles](https://github.com/mapbox/vector-tile-spec/tree/master/2.1) from geographic data sources like [OpenStreetMap](https://www.openstreetmap.org/). Planetiler aims to be fast and memory-efficient so that you can build a map of the world in a few hours on a single machine without any external tools or database. Vector tiles contain raw point, line, and polygon geometries that clients like [MapLibre](https://github.com/maplibre) can use to render custom maps in the browser, native apps, or on a server. Planetiler packages tiles into an [MBTiles](https://github.com/mapbox/mbtiles-spec/blob/master/1.3/spec.md) (sqlite) or [PMTiles](https://github.com/protomaps/PMTiles) file that can be served using tools like [TileServer GL](https://github.com/maptiler/tileserver-gl) or [Martin](https://github.com/maplibre/martin) or even [queried directly from the browser](https://github.com/protomaps/PMTiles/tree/main/js). See [awesome-vector-tiles](https://github.com/mapbox/awesome-vector-tiles) for more projects that work with data in this format. Planetiler works by mapping input elements to vector tile features, flattening them into a big list, then sorting by tile ID to group into tiles. See [ARCHITECTURE.md](ARCHITECTURE.md) for more details or this [blog post](https://medium.com/@onthegomap/dc419f3af75d?source=friends_link&sk=fb71eaa0e2b26775a9d98c81750ec10b) for more of the backstory. ## Demo See the [live demo](https://onthegomap.github.io/planetiler-demo/) of vector tiles created by Planetiler and hosted by the [OpenStreetMap Americana Project](https://github.com/ZeLonewolf/openstreetmap-americana/). [![Planetiler Demo Screenshot](./diagrams/demo.png)](https://onthegomap.github.io/planetiler-demo/) [© OpenMapTiles](https://www.openmaptiles.org/) [© OpenStreetMap contributors](https://www.openstreetmap.org/copyright) ## Usage To generate a map of an area using the [OpenMapTiles profile](https://github.com/openmaptiles/planetiler-openmaptiles), you will need: - Java 21+ (see [CONTRIBUTING.md](CONTRIBUTING.md)) or [Docker](https://docs.docker.com/get-docker/) - at least 1GB of free disk space plus 5-10x the size of the `.osm.pbf` file - at least 0.5x as much free RAM as the input `.osm.pbf` file size #### To build the map: Using Java, download `planetiler.jar` from the [latest release](https://github.com/onthegomap/planetiler/releases/latest) and run it: ```bash wget https://github.com/onthegomap/planetiler/releases/latest/download/planetiler.jar java -Xmx1g -jar planetiler.jar --download --area=monaco ``` Or using Docker: ```bash docker run -e JAVA_TOOL_OPTIONS="-Xmx1g" -v "$(pwd)/data":/data ghcr.io/onthegomap/planetiler:latest --download --area=monaco ``` :warning: This starts off by downloading about 1GB of [data sources](NOTICE.md#data) required by the OpenMapTiles profile including ~750MB for [ocean polygons](https://osmdata.openstreetmap.de/data/water-polygons.html) and ~240MB for [Natural Earth Data](https://www.naturalearthdata.com/).
To download smaller extracts just for Monaco: Java: ```bash java -Xmx1g -jar planetiler.jar --download --area=monaco \ --water-polygons-url=https://github.com/onthegomap/planetiler/raw/main/planetiler-core/src/test/resources/water-polygons-split-3857.zip \ --natural-earth-url=https://github.com/onthegomap/planetiler/raw/main/planetiler-core/src/test/resources/natural_earth_vector.sqlite.zip ``` Docker: ```bash docker run -e JAVA_TOOL_OPTIONS="-Xmx1g" -v "$(pwd)/data":/data ghcr.io/onthegomap/planetiler:latest --download --area=monaco \ --water-polygons-url=https://github.com/onthegomap/planetiler/raw/main/planetiler-core/src/test/resources/water-polygons-split-3857.zip \ --natural-earth-url=https://github.com/onthegomap/planetiler/raw/main/planetiler-core/src/test/resources/natural_earth_vector.sqlite.zip ``` You will need the full data sources to run anywhere besides Monaco.
#### To view tiles locally: Using [Node.js](https://nodejs.org/en/download/): ```bash npm install -g tileserver-gl-light tileserver-gl-light data/output.mbtiles ``` Or using [Docker](https://docs.docker.com/get-docker/): ```bash docker run --rm -it -v "$(pwd)/data":/data -p 8080:8080 maptiler/tileserver-gl -p 8080 ``` Then open http://localhost:8080 to view tiles. Some common arguments: - `--output` tells planetiler where to write output to, and what format to write it in. For example `--output=australia.pmtiles` creates a pmtiles archive named `australia.pmtiles`. - `--download` downloads input sources automatically and `--only-download` exits after downloading - `--area=monaco` downloads a `.osm.pbf` extract from [Geofabrik](https://download.geofabrik.de/) - `--osm-path=path/to/file.osm.pbf` points Planetiler at an existing OSM extract on disk - `-Xmx1g` controls how much RAM to give the JVM (recommended: 0.5x the input .osm.pbf file size to leave room for memory-mapped files) - `--force` overwrites the output file - `--help` shows all of the options and exits ### Git submodules Planetiler has a submodule dependency on [planetiler-openmaptiles](https://github.com/openmaptiles/planetiler-openmaptiles). Add `--recurse-submodules` to `git clone`, `git pull`, or `git checkout` commands to also update submodule dependencies. To clone the repo with submodules: ```bash git clone --recurse-submodules https://github.com/onthegomap/planetiler.git ``` If you already pulled the repo, you can initialize submodules with: ```bash git submodule update --init ``` To force git to always update submodules (recommended), run this command in your local repo: ```bash git config --local submodule.recurse true ``` Learn more about working with submodules [here](https://git-scm.com/book/en/v2/Git-Tools-Submodules). ## Generating a Map of the World See [PLANET.md](PLANET.md). ## Generating Custom Vector Tiles If you want to customize the OpenMapTiles schema or generate an mbtiles file with OpenMapTiles + extra layers, then fork https://github.com/openmaptiles/planetiler-openmaptiles make changes there, and run directly from that repo. It is a standalone Java project with a dependency on Planetiler. If you want to generate a separate mbtiles file with overlay layers or a full custom basemap, then: - For simple schemas, run a recent planetiler jar or docker image with a custom schema defined in a yaml configuration file. See [planetiler-custommap](planetiler-custommap) for details. - For complex schemas (or if you prefer working in Java), create a new Java project that [depends on Planetiler](#use-as-a-library). See the [planetiler-examples](planetiler-examples) project for a working example. If you want to customize how planetiler works internally, then fork this project, build from source, and consider [contributing](#contributing) your change back for others to use! ## Benchmarks Some example runtimes for the OpenMapTiles profile (excluding downloading resources): | Input | Version | Machine | Time | output size | Logs | |------------------------------------------------|---------|---------------------------------|---------------------------|--------------|----------------------------------------------------------------------------------------------------------------| | s3://osm-pds/2024/planet-240115.osm.pbf (69GB) | 0.7.0 | c3d-standard-180 (180cpu/720GB) | 22m cpu:44h34m avg:120 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-c3d-standard-180.txt) | | s3://osm-pds/2024/planet-240108.osm.pbf (73GB) | 0.7.0 | c7gd.16xlarge (64cpu/128GB) | 42m cpu:42m28s avg:52 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-c7gd-128gb.txt) | | s3://osm-pds/2022/planet-220530.osm.pbf (69GB) | 0.5.0 | c6gd.16xlarge (64cpu/128GB) | 53m cpu:41h58m avg:47.1 | 79GB mbtiles | [logs](planet-logs/v0.5.0-planet-c6gd-128gb.txt), [VisualVM Profile](planet-logs/v0.5.0-planet-c6gd-128gb.nps) | | s3://osm-pds/2022/planet-220530.osm.pbf (69GB) | 0.5.0 | c6gd.8xlarge (32cpu/64GB) | 1h27m cpu:37h55m avg:26.1 | 79GB mbtiles | [logs](planet-logs/v0.5.0-planet-c6gd-64gb.txt) | | s3://osm-pds/2022/planet-220530.osm.pbf (69GB) | 0.5.0 | c6gd.4xlarge (16cpu/32GB) | 2h38m cpu:34h3m avg:12.9 | 79GB mbtiles | [logs](planet-logs/v0.5.0-planet-c6gd-32gb.txt) | Merging nearby buildings at z13 is very expensive, when run with `--building-merge-z13=false`: | Input | Version | Machine | Time | output size | Logs | |------------------------------------------------|---------|---------------------------------|--------------------------|--------------|------------------------------------------------------------------------------------------------------------------------------------------------------------| | s3://osm-pds/2024/planet-240115.osm.pbf (69GB) | 0.7.0 | c3d-standard-180 (180cpu/720GB) | 16m cpu:27h45m avg:104 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-c3d-standard-180-no-z13-building-merge.txt) | | s3://osm-pds/2024/planet-240108.osm.pbf (73GB) | 0.7.0 | c7gd.16xlarge (64cpu/128GB) | 29m cpu:23h57 avg:50 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-c7gd-128gb-no-z13-building-merge.txt) | | s3://osm-pds/2024/planet-240108.osm.pbf (73GB) | 0.7.0 | c7gd.2xlarge (8cpu/16GB) | 3h35m cpu:19h45 avg:5.5 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-c7gd-16gb-no-z13-building-merge.txt) | | s3://osm-pds/2024/planet-240108.osm.pbf (73GB) | 0.7.0 | im4gn.large (2cpu/8GB) | 18h18m cpu:28h6m avg:1.5 | 69GB pmtiles | [logs](planet-logs/v0.7.0-planet-im4gn-8gb-no-z13-building-merge.txt) | | s3://osm-pds/2022/planet-220530.osm.pbf (69GB) | 0.5.0 | c6gd.16xlarge (64cpu/128GB) | 39m cpu:27h4m avg:42.1 | 79GB mbtiles | [logs](planet-logs/v0.5.0-planet-c6gd-128gb-no-z13-building-merge.txt), [VisualVM Profile](planet-logs/v0.5.0-planet-c6gd-128gb-no-z13-building-merge.nps) | ## Alternatives Some other tools that generate vector tiles from OpenStreetMap data: - [OpenMapTiles](https://github.com/openmaptiles/openmaptiles) is the reference implementation of the [OpenMapTiles schema](https://openmaptiles.org/schema/) that the [OpenMapTiles profile](https://github.com/openmaptiles/planetiler-openmaptiles) is based on. It uses an intermediate postgres database and operates in two modes: 1. Import data into database (~1 day) then serve vector tiles directly from the database. Tile serving is slower and requires bigger machines, but lets you easily incorporate realtime updates 2. Import data into database (~1 day) then pregenerate every tile for the planet into an mbtiles file which takes [over 100 days](https://github.com/openmaptiles/openmaptiles/issues/654#issuecomment-724606293) or a cluster of machines, but then tiles can be served faster on smaller machines - [Tilemaker](https://github.com/systemed/tilemaker) uses a similar approach to Planetiler (no intermediate database), is more mature, and has a convenient lua API for building custom profiles without recompiling the tool, but takes [about a day](https://github.com/systemed/tilemaker/issues/315#issue-994322040) to generate a map of the world Some companies that generate and host tiles for you: - [Mapbox](https://www.mapbox.com/) - data from the pioneer of vector tile technologies - [Maptiler](https://www.maptiler.com/) - data from the creator of OpenMapTiles schema - [Stadia Maps](https://stadiamaps.com/) - what [onthegomap.com](https://onthegomap.com/) uses in production If you want to host tiles yourself but have someone else generate them for you, those companies also offer plans to download regularly-updated tilesets. ## Features - Supports [Natural Earth](https://www.naturalearthdata.com/), OpenStreetMap [.osm.pbf](https://wiki.openstreetmap.org/wiki/PBF_Format), [`geopackage`](https://www.geopackage.org/), and [Esri Shapefiles](https://en.wikipedia.org/wiki/Shapefile) data sources - Writes to [MBTiles](https://github.com/mapbox/mbtiles-spec/blob/master/1.3/spec.md) or or [PMTiles](https://github.com/protomaps/PMTiles) output. - Java-based [Profile API](planetiler-core/src/main/java/com/onthegomap/planetiler/Profile.java) to customize how source elements map to vector tile features, and post-process generated tiles using [JTS geometry utilities](https://github.com/locationtech/jts) - [YAML config file format](planetiler-custommap) that lets you create custom schemas without writing Java code - Merge nearby lines or polygons with the same tags before emitting vector tiles - Automatically fixes self-intersecting polygons - Built-in OpenMapTiles profile based on [OpenMapTiles](https://openmaptiles.org/) v3.13.1 - Optionally download additional name translations for elements from Wikidata - Export real-time stats to a [prometheus push gateway](https://github.com/prometheus/pushgateway) using `--pushgateway=http://user:password@ip` argument (and a [grafana dashboard](grafana.json) for viewing) - Automatically downloads region extracts from [Geofabrik](https://download.geofabrik.de/) using `geofabrik:australia` shortcut as a source URL - Unit-test profiles to verify mapping logic, or integration-test to verify the actual contents of a generated mbtiles file ([example](planetiler-examples/src/test/java/com/onthegomap/planetiler/examples/BikeRouteOverlayTest.java)) ## Limitations - It is harder to join and group data than when using database. Planetiler automatically groups features into tiles, so you can easily post-process nearby features in the same tile before emitting, but if you want to group or join across features in different tiles, then you must explicitly store data when processing a feature to use with later features or store features and defer processing until an input source is finished ([boundary layer example](https://github.com/onthegomap/planetiler/blob/9e9cf7c413027ffb3ab5c7436d11418935ae3f6a/planetiler-basemap/src/main/java/com/onthegomap/planetiler/basemap/layers/Boundary.java#L294)) - Planetiler only does full imports from `.osm.pbf` snapshots, there is no way to incorporate real-time updates. ## Use as a library Planetiler can be used as a maven-style dependency in a Java project using the settings below: ### Maven Add this repository block to your `pom.xml`: ```xml osgeo OSGeo Release Repository https://repo.osgeo.org/repository/release/ false true ``` Then add the following dependency: ```xml com.onthegomap.planetiler planetiler-core ${planetiler.version} ``` ### Gradle Set up your repositories block:: ```groovy mavenCentral() maven { url "https://repo.osgeo.org/repository/release/" } ``` Set up your dependencies block: ```groovy implementation 'com.onthegomap.planetiler:planetiler-core:' ``` ## Contributing Pull requests are welcome!
