No the library does not provide any function to calculate distance between two coordinates. This library fails to provide any useful functionality or documentation. You need to be the developer of this library if you want to use this library. But you can use something like the haversine formula to get the distance between two coordinates. Below is a implementation of it that gives distance in kilometers
function haversine(lat1: number, lon1: number, lat2: number, lon2: number) {
// distance between latitudes
// and longitudes
let dLat = ((lat2 - lat1) * Math.PI) / 180.0;
let dLon = ((lon2 - lon1) * Math.PI) / 180.0;
// convert to radiansa
lat1 = (lat1 * Math.PI) / 180.0;
lat2 = (lat2 * Math.PI) / 180.0;
// apply formulae
let a =
Math.pow(Math.sin(dLat / 2), 2) +
Math.pow(Math.sin(dLon / 2), 2) * Math.cos(lat1) * Math.cos(lat2);
let rad = 6371;
let c = 2 * Math.asin(Math.sqrt(a));
return (rad * c).toFixed(1);
}
Ahem, I've successfully used this utility in my open-source projects for years, and I'm certainly not a repo developer.
A react-based wrapper for leafletjs shouldn't be expected to provide a capability such as that requested.
In the spirit of Open Source projects, I welcome your future documentation contribution. Thanks Bijay!
Do the package have the disatnce function between two co-ordinate ? like something below? //get the distance between two points let _length = map.distance(_firstLatLng, _secondLatLng);
