A control and integration to display OpenMapSamples vector data in MapLibre-based maps.

OpenMapSamples-MapLibre

OpenMapSamples is a library to generate and provide sample data for testing vector-based map renderings. Sample data is returned as GeoJSON and can be rendered by mapping systems and styles to validate their coverage of combinations of data at different zooms without hand-mapping all possible combinations.

The OpenMapSamples-MapLibre package provides a MapLibre control that allows OpenMapSamples to be swapped for real data in MapLibre-based maps.

You can view a demonstration of this control at https://adamfranco.github.io/OpenMapSamples-examples/. Look for the control in the bottom left of the map and choose a sample to replace the normal map data with sample data and jump to the sample-data locations.

Usage

The SampleControl for MapLibre provides a button and dialog that temporarily replaces the source data in the map's style with sample data.

import SampleControl from 'openmapsamples-maplibre/OpenMapSamplesControl';
import { default as OpenMapTilesSamples } from "openmapsamples/samples/OpenMapTiles";

// Add our sample data.
let sampleControl = new SampleControl({'permalinks': true});

OpenMapTilesSamples.forEach((sample, i) => {
  sampleControl.addSample(sample);
});

// Map is a previously configure maplibre-gl map.
map.addControl(sampleControl, 'bottom-left');
