I tried using this:
function getRandomInRange(from, to, fixed) {
return parseFloat((Math.random() * (to - from) + from).toFixed(fixed));
}
var latLongPairs = 4;
for(var i =0; i<latLongPairs; i++) {
console.log(`${getRandomInRange(-180, 180, 3)}, ${getRandomInRange(-180, 180, 3)}`);
}
That's ok for random numbers like 39.21988,9.124741 but they might end up not valid coordinates. And I need 100 of them.
Your latitude range is incorrect - it should be ±90.
function getRandomInRange(from, to) {
return Math.random() * (to - from) + from;
}
const latLongPairs = 4;
for (let i = 0; i < latLongPairs; ++i) {
let lat = getRandomInRange(-90, 90);
let lon = getRandomInRange(-180, 180);
console.log(`${lat.toFixed(3)}, ${lon.toFixed(3)}`);
}You might need to provide some initial Latitude and longitude with some radius (in meters)
var getRandomLocation = function(latitude, longitude, radiusInMeters) {
var getRandomCoordinates = function(radius, uniform) {
// Generate two random numbers
var a = Math.random(),
b = Math.random();
// Flip for more uniformity.
if (uniform) {
if (b < a) {
var c = b;
b = a;
a = c;
}
}
// It's all triangles.
return [
b * radius * Math.cos(2 * Math.PI * a / b),
b * radius * Math.sin(2 * Math.PI * a / b)
];
};
var randomCoordinates = getRandomCoordinates(radiusInMeters, true);
// Earths radius in meters via WGS 84 model.
var earth = 6378137;
// Offsets in meters.
var northOffset = randomCoordinates[0],
eastOffset = randomCoordinates[1];
// Offset coordinates in radians.
var offsetLatitude = northOffset / earth,
offsetLongitude = eastOffset / (earth * Math.cos(Math.PI * (latitude / 180)));
return `${latitude + (offsetLatitude * (180 / Math.PI))}, ${longitude + (offsetLongitude * (180 / Math.PI))}`
};
for (i = 0; i < 182; i++) {
console.log(getRandomLocation(41.8819, -87.6278, 50))
}
