This example demonstrates how to generate global vector tile sets using OpenMapTiles and Planetiler, processing the entire OpenStreetMap planet file. The code runs Planetiler through Docker with 40GB of Java heap memory, using sparse array node mapping and memory-mapped storage to handle the large dataset efficiently. After generating the output MBTiles file, the script updates its metadata with SQLite commands to set proper attribution, center coordinates, and description for the tiles. The workflow relies on Docker, Planetiler, and sqlite3, with optional pre-downloading of the planet PBF file from OpenStreetMap.

Generate vector tiles for Planet with tilemaker

This example demonstrates a command-line workflow for generating vector tiles from the entire OpenStreetMap planet dataset using tilemaker. It shows how to automate the process of downloading planet-latest.osm.pbf, compiling tilemaker from source, and producing a planet.mbtiles output using the OpenMapTiles configuration and Lua processing scripts. The script also periodically checks the dataset’s last-modified header via curl to trigger regeneration only when new updates exist. External resources like Natural Earth landcover and coastline polygons are fetched and merged into the tile pipeline.

Tuiles vecteur OpenLayers

A web map displays IGN’s PLAN.IGN vector tiles using OpenLayers and the ol-mapbox-style library. The OpenLayers map starts at a zoom level of 5 over France, then fetches the plan’s JSON style from data.geopf.fr and applies it to a hybrid-rendered VectorTile layer. The layer loads Mapbox Vector Tiles from a URL in the style’s source, with attribution added. A brief loading animation occurs while the style is fetched and applied before the map renders.

MBTiles server

This example demonstrates serving map tiles from MBTiles files through multiple server-side implementations. It shows how raster and vector tile data can be exposed via HTTP endpoints using PHP libraries like Tileserver-PHP and MBTiles-PHP, Node.js tools such as Tileserver GL and TileStream, the Go-based mbtileserver, and Python’s python-mbtiles. The code highlights different rendering and delivery approaches, from static raster tiles to server-side vector tile processing, without relying on client-side visualization APIs like d3.geoPath or WebGL. The data source is the MBTiles format, a SQLite-based container for tiled map data.

Gist 89bf9a577b15f0a68bb59055eeb415a1

A map of the Paris region displays IGN-F/Geoportail basemap tiles using Leaflet 1.9.2. The code constructs a `L.tileLayer` that requests WMTS tiles from the `wxs.ign.fr` service, specifying the `GEOGRAPHICALGRIDSYSTEMS.PLANIGNV2` layer with a 256-pixel tile size and zoom levels 0–18. Tile coordinates are inserted into the URL via `{z}`, `{y}`, and `{x}` placeholders. The map is centered on coordinates [48.845, 2.424] at zoom 10 using `L.map().setView`.

Gist 7d99b7d79138bda9a2dfb092728da54c

This example documents a debugging session for serving OpenStreetMap vector tiles with the VersaTiles toolkit. It shows how a version mismatch between the VersaTiles server (0.2.14) and its frontend client causes 404 errors for tile requests, as the server expects flipped Y-axis coordinates (2873/4058) instead of the standard OSM ordering (4058/2873). The fix involves downgrading to versatiles 0.2.13, which resolves the coordinate issue but introduces a client-side gzip decompression error (`Unimplemented type: 3`). The code uses `cargo install`, `versatiles convert`, `versatiles probe`, and `versatiles serve` commands, alongside `curl` for testing tile endpoints, referencing a Geofabrik extract of Pays de la Loire.

Generation GeoJSON des mairies avec code INSEE

This example generates a GeoJSON file of French town halls (mairies) with their INSEE commune codes, distinguishing principal towns from associated communes. It uses `ogr2ogr` with an SQLite dialect to join commune boundaries with their chief-town points from the IGN ADMIN-EXPRESS dataset, applying `PointOnSurface` as a fallback when no official point exists. The resulting output is written with RFC 7946 compliance for modern web mapping. The script downloads a 7z archive and extracts the necessary shapefiles before performing the spatial join.

make a large png from map tiles

This example stitches map tiles into a single large PNG image. It constructs a grid of tiles by fetching them from a specified tile server URL using `wget`, then assembles them with ImageMagick’s `montage` command, first creating vertical bands per column and then concatenating those bands horizontally. The code handles tile caching in a temporary directory, detects image formats with `identify`, and substitutes missing tiles with a placeholder. The process is driven by command-line arguments specifying zoom level and tile coordinates.

R-script voor het downloaden en georefereren van een OpenStreetMap tile

This R script downloads a single OpenStreetMap tile centered on the Martinitoren in Groningen and georeferences it by generating a World file. It first converts latitude and longitude coordinates to tile coordinates using the slippy map tilenames algorithm, then fetches the PNG from the `tile.openstreetmap.org` server. The script calculates the tile’s bounding box from the zoom level and writes a six-line `.pgw` file with pixel-to-world transformation parameters, enabling the image to be overlaid with geographic data in GIS software. The code uses base R functions like `download.file`, `paste0`, and `writeLines` without external libraries.
