Shortest distance between point and path

it helps some times Are you wanting to calculate this in order to say something like "if the pointtopath distance is zero, then remove the point"? If so, then there is probably an easier way to remove redundant nodes. Take the points three at a time (call them A, B, and C). Calculate the angle between A and B, as well as the angle between B and C. If the two angles are the same, then point B lies in the path between A and C and is redundant. You can use the 'atan2' function (or your language's equivalent) to do the angle calculations.

d3.js: distance point to svg:path

I hope this helps . In the general case, I don´t think so. An SVG path is a complex element. For instance, if the path is a Bezier curve, the control points may be off the represented line, and the represented shape may be off the bounding box of the control points. I think that if you have a set of points that you use to generate the path, you may use this points to compute the distance from this points to a given point and get the minimum distance. In the MDN SVG Path Tutorial you can find some examples of complex shapes and how they are made.

validate route distance beetween two point (lat/lng or address) server side with google maps v3

wish help you to fix your issue Yes, But note that the serverside Geocoding service may only be used in conjunction with displaying results on a Google map; Geocoding results without displaying them on a Google map is prohibited by the Google Maps API Terms of Service License Restrictions. If you are looking for geographical distance and not driving distance you can use: code :
function distance($lat1, $lng1, $lat2, $lng2, $miles = true) {
$pi80 = M_PI / 180;
$lat1 *= $pi80;
$lng1 *= $pi80;
$lat2 *= $pi80;
$lng2 *= $pi80;
$r = 6372.797; // mean radius of Earth in km
$dlat = $lat2  $lat1;
$dlng = $lng2  $lng1;
$a = sin($dlat / 2) * sin($dlat / 2) + cos($lat1) * cos($lat2) * sin($dlng / 2) * sin($dlng / 2);
$c = 2 * atan2(sqrt($a), sqrt(1  $a));
$km = $r * $c;
return ($miles ? ($km * 0.621371192) : $km);
}

Meteor calculate distance between users. Server side vs Client Side
By : Mnumnu

This might help you I'd do the filtering on the fetching of the candidates to display. Either as you publish/subscribe on your template or as you fetch in your helper: code :
Meteor.users.find({
"profile.address" : {
$near: {
$geometry: {
type: "Point" ,
coordinates: [ <Employerlongitude> , <Employerlatitude> ]
},
$maxDistance: <distance in meters>,
$minDistance: <distance in meters>
}}}).fetch();

GMap.NET C#, distance between 2 points without Google Distance Matrix Api

fixed the issue. Will look into that further The function I was looking for is named "Distance". This is how to obtain route's distance: code :
inicial = new PointLatLng(googleGeoCoding(txtorigin.Text).Item2,googleGeoCoding(txtorigin.Text).Item3);
final = new PointLatLng(googleGeoCoding(txtdest.Text).Item2, googleGeoCoding(txtdest.Text).Item3);
GDirections routedir;
var routefromtable = GMapProviders.GoogleMap.GetDirections(out routedir, inicial, final, chbxhighways.Checked, chbxtolls.Checked, rbtnwalking.Checked, false, false);
GMapRoute tablemaproute = new GMapRoute(routedir.Route, "Ruta ubication");
GMapOverlay tablerouteoverlay = new GMapOverlay("Capa de la ruta");
tablerouteoverlay.Routes.Add(tablemaproute);
gMapControl1.Overlays.Add(tablerouteoverlay);
gMapControl1.Zoom = gMapControl1.Zoom + 1;
gMapControl1.Zoom = gMapControl1.Zoom  1;
double distance = tablemaproute.Distance;
MessageBox.Show(distance.ToString());
