- OpenMapTiles provides open-source tools for creating vector map tiles from various data sources like OpenStreetMap, Wikidata, and Natural Earth. - It defines a vector tile schema and style specifications that are used by organizations like the Luxembourg national geoportal. - Pre-generated global and regional map tilesets are freely available for non-commercial use and updated weekly, while the full toolchain is open-source on GitHub for generating custom tiles.
OpenMapTiles FOSS4G 2019
- 1. OpenMapTiles News, thematic layers, coordinate systems Petr Sloup <petr.sloup@maptiler.com>
- 2. About OpenMapTiles - Set of open-source tools for vector maps - 200 million people see OpenMapTiles every month - https://openmaptiles.org/ - https://github.com/openmaptiles
- 3. 1. Vector tile schema - Defines map layers and attributes - e.g. buildings, road, ... https://openmaptiles.org/schema/ - Independent of the source data - Usually OpenStreetMap - Can also be used for your own data - Adopted by Luxembourg's national geoportal - Institut Cartogràfic i Geològic de Catalunya - Inspiration for Ordnance Survey OpenZoomStack
- 4. 2. Creating vector tiles - Combination of several sources - OpenStreetMap - Wikidata (for 63 languages) - Natural Earth (for nice overviews) - The tools can be modified to work with your own data instead
- 5. 3. Ready-to-use map styles - Several styles ready to be used - Many visually different maps from the same vector tiles - Compatible with any data following the schema - With prepared sprites and fonts
- 6. Latest releases - docks and piers - multilingual street names - park names - POI improvements 3.9 - Nov 2018 - transportation layer - multi level roads, bridges - water layer improvements - bridges, aqueducts, labels 3.8 - May 2018 - water layers updates - missing islands, intermittent rivers - boundary fixes - volcanoes - POIs - dormitories, parking - Indonesian, Basque/Euskara, Occitan and Corsican 3.10 - June 2019
- 7. 3.11 - planned features - planned to release in Q4 2019 - make contributions easier - review and update external repositories - rendering of administrative boundaries - revision of used Natural Earth data - try to reduce number of repositories
- 8. Generate the map yourself - all sources available on GitHub with tutorials https://github.com/openmaptiles/openmaptiles - for simple start use ./quickstart.sh - https://openmaptiles.org/docs/
- 9. … or download pre-generated tiles - The map tiles for selected areas - Planet, continents, countries, cities, … - Free to download (for non-commercial use) - Regular weekly updates available - Additional global data: - Contour lines vector tiles for planet - Global hillshading raster tiles - Global cleaned DEM data
- 10. Project vision - universal map schema for many applications - create a beautiful basemaps with general layers that contain topographic information - keep the low size of the tiles and planet (60-70 GB)
- 11. Custom additional layers - Any “custom” layer can be created as a separate tileset - Process only the data you need, use the core OpenMapTiles data for the rest - Utilize the whole OpenMapTiles toolchain - Sample for creating custom skiing layer from OpenStreetMap https://github.com/openmaptiles/openmaptiles-skiing - Step-by-step guide on State of the map 2018 https://youtu.be/bdOjVghEx3E (or search for “SOTM 2018 OpenMapTiles”)
- 12. Real-world examples - Outdoor - Hiking, Cycling, Skiing - Open Infrastructure Map
- 13. Thematic layers - additional thematic map data components - in MapTiler Cloud free for non-commercial - layers: - Hiking - soon available - Winter sports - in progress - Infrastructure - Sea map
- 14. - OpenMapTiles pipeline can be modified to create tiles in custom coordinate systems and grids - Great for local (national) coordinate systems Coordinate systems – Beyond Mercator
- 15. - PBF-encoded MVT - Stored in GeoPackage - Full possibility of Tile Matrix Set definition - Utilizing work-in-progress Vector Tiles extension spec - Displayed with OpenLayers + proj4js - Actually correct TileGrid definition - Easy to combine with your own data (raster or vector) - Using ol-mapbox-style to apply GL JSON styles Coordinate systems – How it’s done
- 16. Coordinate systems – Try now - WGS84 (EPSG:4326) available now in MapTiler Cloud! - more coordinate systems coming soon - including ready-to-use OpenLayers example - Vector tiles with correctly defined TileGrid - rasterized tiles also available - XYZ, WMTS and Static Maps API https://cloud.maptiler.com/maps/basic-4326/
