Add points from geojson

1. Create your empty map on pro.getwemap.com and get your emmid & token​

2. Add snippet to your website​

Include CSS rules and JavaScript library on top of your HTML file.

<style>
    body, html{ height: 100%; }
</style>
<script type='application/javascript' src='https://livemap.getwemap.com/js/sdk.min.js'></script>

Include the following code in the <body> of your HTML file.

<div id='map-container' style='width: 100%; height: 100%;'></div>

3. Create points and map​

Nexts steps are:

  • Create map
  • Create your Pinpoints from data
  • Fit map to your Pinpoints bounds
<script>
    // Create your map
    var container = document.getElementById('map-container');
    var options = {
        emmid: 7439,
        token: 'Y6TBX2RX7HUP21XCCMFNHM6AV'
    };
    var livemap = wemap.v1.createLivemap(container, options);

    // Create Pinpoints from geojson

    var geojsonToPinpoints = (featuresCollection) => {
        var features = featuresCollection.features.filter(feat => {
            return feat.geometry.type === 'Point';
    });
    var id = 0;
    var pinpoints = features.map(feat => {
      return {
        id: id++,
        name: feat.properties.name,
        latitude: feat.geometry.coordinates[1],
        longitude: feat.geometry.coordinates[0],
        description: feat.properties.description,
        type: feat.properties.media_url ? 2 : 1,
        media_url: feat.properties.media_url,
        media_type: feat.properties.media_url ? 'image' : undefined
      };
    });
    return pinpoints;
  };

  // Don't forget to use the waitForReady function
  // If you don't you could have some issue with the map handling functions like fitBounds
  livemap.waitForReady().then(function() {
    fetch('https://gist.githubusercontent.com/bertrandmd/99656cbee2c6b81607cce3243137cf35/raw/74aae01eb4ee84a5d96db7139a7c6275371dd150/example.geojson')
    .then(resp => resp.json())
    .then(data => {
        var pinpoints = geojsonToPinpoints(data);
  
        // Add your Pinpoint to the map
        return livemap.setPinpoints(pinpoints);         
    })
    .then(response => {
       var bounds = response.bounds;
       var options = {
           padding: {bottom: 0, top: 65, left: 0, right:0}
       }
       livemap.fitBounds(bounds.toArray(), options);
    });
  });
</script>

4. Et voilà !​
