PMTiles for OpenLayers
See the openlayers/ directory in the PMTiles repository for using PMTiles with OpenLayers.
Quick Example
Example of vector tiles (New Zealand buildings): Live demo
Example of raster tiles (RGB Terrain): Live demo
Using with a Bundler
It's recommended to use OpenLayers with a build system to reduce the final size of the JavaScript code. To get started with PMTiles, follow the OpenLayers Quick Start.
Add ol-pmtiles
to your project:
npm install ol-pmtiles
Then create a source depending on whether your data source is vector or raster tiles:
js
import "./style.css";
import { Map, View } from "ol";
import WebGLTile from "ol/layer/WebGLTile";
import { PMTilesRasterSource } from "ol-pmtiles";
import { useGeographic } from 'ol/proj';
const rasterLayer = new WebGLTile({
source: new PMTilesRasterSource({
url:"https://r2-public.protomaps.com/protomaps-sample-datasets/terrarium_z9.pmtiles",
attributions:["https://github.com/tilezen/joerd/blob/master/docs/attribution.md"],
tileSize: [512,512]
})
});
useGeographic();
const map = new Map({
target: "map",
layers: [rasterLayer],
view: new View({
center: [0,0],
zoom: 1,
}),
});
js
import "./style.css";
import { Map, View } from "ol";
import VectorTile from "ol/layer/VectorTile";
import { PMTilesVectorSource } from "ol-pmtiles";
import { Style, Stroke, Fill } from 'ol/style';
import { useGeographic } from 'ol/proj';
const vectorLayer = new VectorTile({
declutter: true,
source: new PMTilesVectorSource({
url: "https://r2-public.protomaps.com/protomaps-sample-datasets/nz-buildings-v3.pmtiles",
attributions: ["© Land Information New Zealand"],
}),
style: new Style({
stroke: new Stroke({
color: "gray",
width: 1,
}),
fill: new Fill({
color: "rgba(20,20,20,0.9)",
}),
}),
});
useGeographic();
const map = new Map({
target: "map",
layers: [vectorLayer],
view: new View({
center: [172.606201,-43.556510],
zoom: 7,
}),
});
