This example shows a map centered on a region in France, displaying a WMS layer of urban areas from 1980 over a basemap. The map uses the maplibre-gl library to render the WebGL map. A raster data source is added via a proxied WMS URL, with the GetMap request specifying the layer, coordinate system, and bounding box. The WMS tiles are integrated using the `map.addSource` and `map.addLayer` APIs.

Add a WMS source untiled

This example shows a MapLibre GL map displaying a French urban-area layer from a WMS service, overlaid on OpenStreetMap raster tiles. The map fetches a WMS GetMap request for the current viewport, using the SphericalMercator library to convert map bounds into EPSG:3857 coordinates for the request. When the user pans or zooms, the `moveend` event triggers removal and re-addition of the image source and raster layer, refreshing the WMS overlay. The code uses `map.addSource` and `map.addLayer` to manage the dynamic image layer.

Leaflet WMS

This example shows a map centered on a region in France, displaying both urban areas from a French government WMS layer alongside a French statistical data layer, with a scale bar. Built with the Leaflet JavaScript library, it combines OpenStreetMap tiles with two Web Map Service (WMS) layers. The first WMS source, accessed via a proxy from `data.europa.eu`, uses `L.WMS.source` and `source.getLayer("Tache_urbaine_1980_R43")`, while the second uses `L.tileLayer.wms` to load INSEE income data from an IGN endpoint.

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`.

Display a map

This example displays an interactive map of France using the Maplibre GL JS library. Two map styles are showcased: a standard topographic map from the IGN PLAN.IGN vector tiles, and an isohypse (contour line) style with an orange monochrome rendering, centered on the Alps. The code fetches style definitions as JSON and applies them to the map, adjusting the tile scheme for compatibility. Attribution is provided to the IGN data source.

Display cadastre on Maplibre

This interactive map displays the French land registry, or cadastre, within the Maplibre GL rendering engine. It shows administrative boundaries—from regions down to individual communes—along with detailed cadastral sections, parcels, and buildings. Using the WebGL-driven Maplibre GL API, it loads vector tile sources from `openmaptiles.geo.data.gouv.fr`, with parcel lines appearing at zoom level 16 and property numbers labeled for identification. The styling, defined in a JSON style sheet, uses fill and line layers with conditional opacity to highlight parcels.

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.

Gist 9496726

This example displays a MapBox base map using a GDAL WMS configuration that defines a TMS service, projecting the entire world in EPSG:3857 with tile levels up to 18. The XML file specifies the server URL, data window boundaries, and 256x256 pixel blocks with three color bands, effectively rendering satellite or street imagery as a raster layer. The visualization relies on GDAL’s WMS driver to fetch tiles from MapBox’s servers, with a cache enabled for performance. It does not use JavaScript libraries like d3 or Three.js, focusing instead on a server-side tile definition for seamless map display.

A Leaflet map centered on France displays a circular buffer polygon around a point at coordinates (2.18, 46). The example uses proj4js and the reproject library to convert the point from WGS84 to EPSG:3857, then applies jsts.io.GeoJSONReader to read the geometry and create a 40,000-meter buffer via the jsts buffer method. After writing the buffered geometry back to GeoJSON, it reprojects to WGS84 and renders the result as a Leaflet GeoJSON layer on OpenStreetMap tiles, with a scale control and a marker at (0,0).
