How are OpenStreetMap PBF files related to MapBox vector tiles?
Vector tiles are encoded as Google Protobufs (PBF), which allow for serializing structured data. For clarity, Mapbox Vector Tiles use the.mvt file suffix. The specification details are largely structured around the rules implemented in the base.proto file. How are OpenStreetMap PBF files related to Mapbox Vector Tiles?
Can a PBF file be used as a vector tile?
Mapbox Vector Tiles and OpenStreetMap PBFs are protobuf files, but conform to completely different specifications and are used in different ways. To encode geographic information into a vector tile a tool must convert geographic coordinates, such as latitude and longitude, into vector tile grid coordinates.
How to create vector tiles in Mapbox Studio?
The repo contains two MapBox Studio Classic projects: data source (.tm2source) and style (.tm2) necessary to create custom vector tiles (protobuf encoded MVT – MapBox Vector Tiles) packed in MBTiles and shows what can be done with such tiles.
How to render a tile from a.pbf or.osm file?
There are some advantages: Like Mapsui features, SKPicture is a vector image. So it draws always with very good quality. But it could be transfered to a PNG or JPG very easy. Coordinates from the vector data (here integers between 0 and 4095) could be used directly.
How to convert OSM data to MapBox format?
Be aware that OSM files include many data layers and the structure is quite specific, so you need to find well-working configurations for all conversion steps. The mapbox/awesome-vector-tiles repository at GitHub has a long list of Mapbox Vector Tile implementations.
Mapbox Studio – Desktop design studio for both creating vector tiles from raw geodata and for rendering them on-the-fly into image tiles. Internally uses tilelive.js modules to handle vector tiles (see tilelive-bridge and tilelive-vector)
