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

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
