Using An Array Of Longitudes And Latitudes To Plot On Mapbox
i am trying to implement Mapbox api into my web application however i have reached a snag. My objective is to grab the longitudes and latitudes from my array and insert them into t
Solution 1:
I've got no mapbox experience, but basing on this documentation page, i came up with following;
You need to create your features collection (array) within for loop, like that:
var featureCollection = []; // Initialize empty collection// Your longLat collectionvar longLat = [
[53.515333, -6.190796],
[53.342686, -6.403656],
[51.678091, -9.624023],
[52.768293, -1.560059]
];
// for every item object within longLatfor(var itemIndex in longLat) {
// push new feature to the collection
featureCollection.push({
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": longLat[itemIndex]
},
"properties": {
"title": "Mapbox DC",
"icon": "monument"
}
});
}
Try if you can skip the properties (icon and title). For now they are hardcoded.
Then, you pass them to the map itself this way:
map.on('load', function () {
map.addLayer({
"id": "points",
"type": "symbol",
"source": {
"type": "geojson",
"data": {
"type": "FeatureCollection",
"features": featureCollection
}
},
"layout": {
"icon-image": "{icon}-15",
"text-field": "{title}",
"text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"],
"text-offset": [0, 0.6],
"text-anchor": "top"
}
});
});
I'm not sure what all of the things mean (like layout
with all icons for example), but that's just taken from the mentioned example, so it should not break anything.
