Am using here map.
I have a list of objects which has all the latitude and longitude of a particular region from a map as below
//Texas points
let list = [
{ lat: 36.5098, lng: -103.0559 },
{ lat: 32.0456, lng: -103.0559 },
{ lat: 32.0456, lng: -106.6103 },
{ lat: 30.827, lng: -105.385 },
{ lat: 29.631, lng: -104.4622 },
{ lat: 29.018, lng: -103.1878 },
{ lat: 29.898, lng: -102.3528 },
{ lat: 27.3525, lng: -99.5403 },
{ lat: 25.9106, lng: -97.2943 },
{ lat: 28.3933, lng: -96.5692 },
{ lat: 29.6994, lng: -93.8665 },
{ lat: 33.5523, lng: -94.0423 },
{ lat: 34.5897, lng: -99.9969 },
{ lat: 36.4848, lng: -99.9969 },
{ lat: 36.5098, lng: -103.0559 },
{ lat: 33.3507, lng: -98.283 },
{ lat: 32.4281, lng: -94.8553 },
{ lat: 26.8358, lng: -98.0853 },
{ lat: 30.9512, lng: -98.5247 },
{ lat: 31.4773, lng: -105.2484 }
];
Is there a way to find out the boundary points from the above list. Any ideas how to approach this. Thanks in advance.
Answer
function addPolygonToMap(map) {
let str = [];
for (let i = 0; i < list.length; i++) {
str.push(parseFloat(list[i].lat));
str.push(parseFloat(list[i].lng));
str.push(0);
}
var geoStrip = new H.geo.Strip([...str], "values lat lng alt");
map.addObject(
new H.map.Polygon(geoStrip, {
style: {
fillColor: "red",
strokeColor: "#829",
lineWidth: 4
}
})
);
}
