Creating a featurelayer from an array of locations

BushraSyed1 — Thu, 13 Jan 2022 20:26:55 GMT

Hello!

I was wondering if it would be possible to turn a 2d array of latitude and longitude into a featurelayer? Would this be difficult to accomplish? This is what the data looks like:

var data = [ { "latitude": 59.441193, "longitude": 24.729494 }, { "latitude": 59.432365, "longitude": 24.742992 }, { "latitude": 59.431602, "longitude": 24.757563 }, { "latitude": 59.437843, "longitude": 24.765759 }, { "latitude": 59.439644, "longitude": 24.779041 }, { "latitude": 59.434776, "longitude": 24.756681 } ];

You can iterate over the array and add them to the source of the FeatureLayer.

const data = [ { latitude: 59.441193, longitude: 24.729494 }, { latitude: 59.432365, longitude: 24.742992 }, { latitude: 59.431602, longitude: 24.757563 }, { latitude: 59.437843, longitude: 24.765759 }, { latitude: 59.439644, longitude: 24.779041 }, { latitude: 59.434776, longitude: 24.756681 }, ]; const featureLayer = new FeatureLayer({ geometryType: "point", objectIdField: "OBJECTID", source: data.map((a) => ({ geometry: { type: "point", ...a, }, })), });
